What type of recording did Brandenburg use?

Karlheinz Brandenburg used a CD recording of Suzanne Vega's song "Tom's Diner" to assess and refine the MP3 compression algorithm. This song was chosen because of its nearly monophonic nature and wide spectral content, making it easier to hear imperfections in the compression format during playbacks. Some refer to Suzanne Vega as "The mother of MP3". This particular track has an interesting property in that the two channels are almost, but not completely, the same, leading to a case where Binaural Masking Level Depression causes spatial unmasking of noise artifacts unless the encoder properly recognizes the situation and applies corrections similar to those detailed in the MPEG-2 AAC psychoacoustic model. Some more critical audio excerpts (glockenspiel, triangle, accordion, etc.) were taken from the EBU V3/SQAM reference compact disc and have been used by professional sound engineers to assess the subjective quality of the MPEG Audio formats.

Who developed the reference simulation software?

A reference simulation software implementation, written in the C language and later known as ISO 11172-5, was developed (in 1991–1996) by the members of the ISO MPEG Audio committee in order to produce bit compliant MPEG Audio files (Layer 1, Layer 2, Layer 3). It was approved as a committee draft of ISO/IEC technical report in March 1994 and printed as document CD 11172-5 in April 1994. It was approved as a draft technical report (DTR/DIS) in November 1994, finalized in 1996 and published as international standard ISO/IEC TR 11172-5:1998 in 1998. The reference software in C language was later published as a freely available ISO standard. Working in non-real time on a number of operating systems, it was able to demonstrate the first real time hardware decoding (DSP based) of compressed audio. Some other real time implementation of MPEG Audio encoders were available for the purpose of digital broadcasting (radio DAB, television DVB) towards consumer receivers and set top boxes.

When was the first software MP3 encoder released?

On 7 July 1994, the Fraunhofer Society released the first software MP3 encoder called l3enc. The filename extension .mp3 was chosen by the Fraunhofer team on 14 July 1995 (previously, the files had been named .bit). With the first real-time software MP3 player WinPlay3 (released 9 September 1995) many people were able to encode and play back MP3 files on their PCs. Because of the relatively small hard drives back in that time (~ 500–1000 MB) lossy compression was essential to store non-instrument based (see tracker and MIDI) music for playback on computer.


What was the name of the first software MP3 encoder?


What was the name of the first real-time software MP3 player?


What was the average high end hard drive size?


As sound scholar Jonathan Sterne notes, "An Australian hacker acquired l3enc using a stolen credit card. The hacker then reverse-engineered the software, wrote a new user interface, and redistributed it for free, naming it "thank you Fraunhofer"".


Which nationality was the hacker who acquired I3enc?


What did the hacker use to acquire the software?


The hacker re-wrote which element of the program?


How much did the new released program by the hacker cost?


In the second half of '90s, MP3 files began to spread on the Internet. The popularity of MP3s began to rise rapidly with the advent of Nullsoft's audio player Winamp, released in 1997. In 1998, the first portable solid state digital audio player MPMan, developed by SaeHan Information Systems which is headquartered in Seoul, South Korea, was released and the Rio PMP300 was sold afterwards in 1998, despite legal suppression efforts by the RIAA.


Which audio player was released in 1997?


What was the name of the first portable solid state digital audio player?


In which country was the first portable audio player developed?


In November 1997, the website mp3.com was offering thousands of MP3s created by independent artists for free. The small size of MP3 files enabled widespread peer-to-peer file sharing of music ripped from CDs, which would have previously been nearly impossible. The first large peer-to-peer filesharing network, Napster, was launched in 1999.


How many MP3s were offered for free by the website?


What kind of file sharing became popular due to the file sizes of MP3s?


How did people come into possession of MP3s?


Which network was the first large peer to peer file sharing network?


What kind of infringement resulted from sharing MP3s?

The ease of creating and sharing MP3s resulted in widespread copyright infringement. Major record companies argued that this free sharing of music reduced sales, and called it "music piracy". They reacted by pursuing lawsuits against Napster (which was eventually shut down and later sold) and against individual users who engaged in file sharing.


What name did the record companies associate with MP3 file sharing?


Who was the target of the record companies?


What kind of MP3 file sharing continues on?

Unauthorized MP3 file sharing continues on next-generation peer-to-peer networks. Some authorized services, such as Beatport, Bleep, Juno Records, eMusic, Zune Marketplace, Walmart.com, Rhapsody, the recording industry approved re-incarnation of Napster, and Amazon.com sell unrestricted music in the MP3 format.


Beatport, Bleep and Juno records are examples of what kind of service?


What kind of music is sold by these companies?


Which format is used by the companies that sell the music legally?


A header and data block together make up what?

An MP3 file is made up of MP3 frames, which consist of a header and a data block. This sequence of frames is called an elementary stream. Due to the "byte reservoir", frames are not independent items and cannot usually be extracted on arbitrary frame boundaries. The MP3 Data blocks contain the (compressed) audio information in terms of frequencies and amplitudes. The diagram shows that the MP3 Header consists of a sync word, which is used to identify the beginning of a valid frame. This is followed by a bit indicating that this is the MPEG standard and two bits that indicate that layer 3 is used; hence MPEG-1 Audio Layer 3 or MP3. After this, the values will differ, depending on the MP3 file. ISO/IEC 11172-3 defines the range of values for each section of the header along with the specification of the header. Most MP3 files today contain ID3 metadata, which precedes or follows the MP3 frames, as noted in the diagram.

What is used to identify the begining of a valid frame of an MP3 header?


How many bits are needed to indicate that layer 3 is used?


MP3 files today contain what kind of metadeta?


Which standard does not include a specification for an MP3 encoder?

The MPEG-1 standard does not include a precise specification for an MP3 encoder, but does provide example psychoacoustic models, rate loop, and the like in the non-normative part of the original standard. At present, these suggested implementations are quite dated. Implementers of the standard were supposed to devise their own algorithms suitable for removing parts of the information from the audio input. As a result, there are many different MP3 encoders available, each producing files of differing quality. Comparisons are widely available, so it is easy for a prospective user of an encoder to research the best choice. An encoder that is proficient at encoding at higher bit rates (such as LAME) is not necessarily as good at lower bit rates.


Example psychoacoustic models and rate loops can be foundin which part of the original standard?


What were implementers of the standard supposed to devise?


It is easy for a prospective user of an encoder to research the best choice because of what factor?


An encoder that is proficient at encoding at higher bit rates might be worse at what?


How many domain samples are taken during encoding?

During encoding, 576 time-domain samples are taken and are transformed to 576 frequency-domain samples.[clarification needed] If there is a transient, 192 samples are taken instead of 576. This is done to limit the temporal spread of quantization noise accompanying the transient. (See psychoacoustics.)


Domain samples are transformed into what?


When are 192 samples taken instead of 576?


When 192 samples are taken instead of 576, it is done in an effort to limit what?


What kind of structure does a filter bank have?

Due to the tree structure of the filter bank, pre-echo problems are made worse, as the combined impulse response of the two filter banks does not, and cannot, provide an optimum solution in time/frequency resolution. Additionally, the combining of the two filter banks' outputs creates aliasing problems that must be handled partially by the "aliasing compensation" stage; however, that creates excess energy to be coded in the frequency domain, thereby decreasing coding efficiency.[citation needed]


Due to a specific kind of structure, what kind of problems are made worse?


What kind of resolution are the filter banks unable to provide an optimal solution for?


Combining two filter banks' outputs creates what kind of problem?


The need to code excess energy in the frequency domain decreases what kind of efficiency?


What is carefully defined in the standard?

Decoding, on the other hand, is carefully defined in the standard. Most decoders are "bitstream compliant", which means that the decompressed output that they produce from a given MP3 file will be the same, within a specified degree of rounding tolerance, as the output specified mathematically in the ISO/IEC high standard document (ISO/IEC 11172-3). Therefore, comparison of decoders is usually based on how computationally efficient they are (i.e., how much memory or CPU time they use in the decoding process).


The ISO/IEC high standard document states that the decompressed output produced from a given MP3 file will be the same within what standards?


Decoders are usually compared by examining which factor?


The efficiency of decoders is examined by seeing how much memory and what other process they use in the decoding process?


What is there no official provision for?

Encoder / decoder overall delay is not defined, which means there is no official provision for gapless playback. However, some encoders such as LAME can attach additional metadata that will allow players that can handle it to deliver seamless playback.


What is an example of an encoder that can attach additional metadeta?


Adding additional metadata allows players to handle gapless playback and deliver what?


For encoders and decoders, what is not defined?


A typical trade off when creating an MP3 file is between the amount of space used and what other factor?

When performing lossy audio encoding, such as creating an MP3 file, there is a trade-off between the amount of space used and the sound quality of the result. Typically, the creator is allowed to set a bit rate, which specifies how many kilobits the file may use per second of audio. The higher the bit rate, the larger the compressed file will be, and, generally, the closer it will sound to the original file.


What would an example of lossy audio encoding be?


Who gets to set the bit rate for an MP3 file?


What does the bit rate of the file actually mean?


If the bit rate is higher, the size of the compressed file will be what?


If the bit rate is too low, what might be audible in the reproduction?

With too low a bit rate, compression artifacts (i.e., sounds that were not present in the original recording) may be audible in the reproduction. Some audio is hard to compress because of its randomness and sharp attacks. When this type of audio is compressed, artifacts such as ringing or pre-echo are usually heard. A sample of applause compressed with a relatively low bit rate provides a good example of compression artifacts.


Sounds that were not in the original recording are referred to as what?


Randomness and sharp attacks are two reasons that may make it harder to to do what to an audio file?


Other than pre - echo, what is another example of what can happen when audio is compressed?


What kind of sample can display a good example of compression artifacts?


Other than the bit rate and the difficulty of the signal, what can also affect the quality of an MP3 file?

Besides the bit rate of an encoded piece of audio, the quality of MP3 files also depends on the quality of the encoder itself, and the difficulty of the signal being encoded. As the MP3 standard allows quite a bit of freedom with encoding algorithms, different encoders may feature quite different quality, even with identical bit rates. As an example, in a public listening test featuring two different MP3 encoders at about 128 kbit/s, one scored 3.66 on a 1–5 scale, while the other scored only 2.22.


The MP3 standard allows encoders to have a lot of freedom with which aspect of encoding?


As a result of the freedom, different encoders can result in different quality even if which aspect of the file is the same?


An example shown has a low range quality score of what value?


To compare qualities, sound files are evaluated on a scale that ranges from 1 to what?


How many bit rates does the simplest type of MP3 file use?

The simplest type of MP3 file uses one bit rate for the entire file: this is known as Constant Bit Rate (CBR) encoding. Using a constant bit rate makes encoding simpler and faster. However, it is also possible to create files where the bit rate changes throughout the file. These are known as Variable Bit Rate (VBR) files. The idea behind this is that, in any piece of audio, some parts will be much easier to compress, such as silence or music containing only a few instruments, while others will be more difficult to compress. So, the overall quality of the file may be increased by using a lower bit rate for the less complex passages and a higher one for the more complex parts. With some encoders, it is possible to specify a given quality, and the encoder will vary the bit rate accordingly. Users who know a particular "quality setting" that is transparent to their ears can use this value when encoding all of their music, and generally speaking not need to worry about performing personal listening tests on each piece of music to determine the correct bit rate.


Aside from silence, which sections of music highlight parts that are easier to compress?


What value do users need to know when encoding their music to help avoid them having to do tests on each piece of music?


A listening environment is also know by which term?

Perceived quality can be influenced by listening environment (ambient noise), listener attention, and listener training and in most cases by listener audio equipment (such as sound cards, speakers and headphones).


Other than speakers and headphones, what other piece of equipment affects the listener's perceived quality?


Listening environment, listener attention, listener training and listener audio equipment can all affect what kind of quality?


Who gave students a test to determine their preferences?

A test given to new students by Stanford University Music Professor Jonathan Berger showed that student preference for MP3-quality music has risen each year. Berger said the students seem to prefer the 'sizzle' sounds that MP3s bring to music.

Data showed that students' preference for MP3 quality music followed which trend?


What kind of sound did students seem to prefer?


What is the name of the study done by composer Ryan Maguire?

An in-depth study of MP3 audio quality, sound artist and composer Ryan Maguire's project "The Ghost in the MP3" isolates the sounds lost during MP3 compression. In 2015, he released the track "moDernisT" (an anagram of "Tom's Diner"), composed exclusively from the sounds deleted during MP3 compression of the song "Tom's Diner", the track originally used in the formulation of the MP3 standard. A detailed account of the techniques used to isolate the sounds deleted during MP3 compression, along with the conceptual motivation for the project, was published in the 2014 Proceedings of the International Computer Music Conference.


What is the track "moDernisT" an anagram of?


Where was an account of the study published?


What is the name of the sampling theorem?

Several bit rates are specified in the MPEG-1 Audio Layer III standard: 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256 and 320 kbit/s, with available sampling frequencies of 32, 44.1 and 48 kHz. MPEG-2 Audio Layer III allows bit rates of 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 144, 160 kbit/s with sampling frequencies of 16, 22.05 and 24 kHz. MPEG-2.5 Audio Layer III is restricted to bit rates of 8, 16, 24, 32, 40, 48, 56 and 64 kbit/s with sampling frequencies of 8, 11.025, and 12 kHz.[citation needed] Because of the Nyquist–Shannon sampling theorem, frequency reproduction is always strictly less than half of the sampling frequency, and imperfect filters requires a larger margin for error (noise level versus sharpness of filter), so 8 kHz sampling rate limits the maximum frequency to 4 kHz, while 48 kHz maximum sampling rate limits an MP3 to 24 kHz sound reproduction.


In relation to the sampling frequency, the frequency reproduction is strictly how much less?


Having an 8 kHz sampling rate would limit the maximum frequency to how much?


What kind of filter requires a larger margin for error?


A sound reproduction of 24 kHz would represent which value of a maximum sampling rate?


What sampling rate is used for CD audio?

A sample rate of 44.1 kHz is almost always used, because this is also used for CD audio, the main source used for creating MP3 files. A greater variety of bit rates are used on the Internet. The rate of 128 kbit/s is commonly used, at a compression ratio of 11:1, offering adequate audio quality in a relatively small space. As Internet bandwidth availability and hard drive sizes have increased, higher bit rates up to 320 kbit/s are widespread.


What is the main source used for creating MP3 files?


Where can one find a greater variety of bit rates?


The common bit rate on the internet is 128 kbit/s using which compression ratio?


As technology advances, what is another higher bit rate that is beginning to spread?


What is stored on an audio-CD that has a bit rate of 1,411.2 kbit/s?

Uncompressed audio as stored on an audio-CD has a bit rate of 1,411.2 kbit/s, (16 bit/sample × 44100 samples/second × 2 channels / 1000 bits/kilobit), so the bitrates 128, 160 and 192 kbit/s represent compression ratios of approximately 11:1, 9:1 and 7:1 respectively.


What does a bit rate of 128 represent in terms of compression ratio?


What would a bit rate of 160 correspond to in terms of compression ratio?


What would a bit rate of 192 kbit/s have for a compression ratio?


The LAME encoder allows bit rates that are what?

Non-standard bit rates up to 640 kbit/s can be achieved with the LAME encoder and the freeformat option, although few MP3 players can play those files. According to the ISO standard, decoders are only required to be able to decode streams up to 320 kbit/s.


Even though few MP3 players can play it, LAME also offers which option?


What is the highest bit rate the LAME encoder allows?


The ISO standard dictates that decoders only need to be able to decode streams that have how high of a bit rate?


Early MPEG Layer III encoders used what is now called Constant Bit Rate (CBR). The software was only able to use a uniform bitrate on all frames in an MP3 file. Later more sophisticated MP3 encoders were able to use the bit reservoir to target an average bit rate selecting the encoding rate for each frame based on the complexity of the sound in that portion of the recording.


The early software was restricted to which kind of bitrate?


What did more sophisticated MP3 encoders use to target an average bit rate?


What did encoders base the encoding rate for each frame on?


What kind of audio can a sophisticated MP3 encoder produce?

A more sophisticated MP3 encoder can produce variable bitrate audio. MPEG audio may use bitrate switching on a per-frame basis, but only layer III decoders must support it. VBR is used when the goal is to achieve a fixed level of quality. The final file size of a VBR encoding is less predictable than with constant bitrate. Average bitrate is VBR implemented as a compromise between the two: the bitrate is allowed to vary for more consistent quality, but is controlled to remain near an average value chosen by the user, for predictable file sizes. Although an MP3 decoder must support VBR to be standards compliant, historically some decoders have bugs with VBR decoding, particularly before VBR encoders became widespread.


Which type of decoder must support bitrate switching on a per-frame basis?


What do encoders use when the goal is to achieve a fixed level of quality?


Using VBR instead of a constant bit rate encoding makes which part of encoding less predictable?


An average bit rate is used when who choses an average value for the encoder to use?


A partially full frame's ability to have part of the next frame's audio data is referred to as what?

Layer III audio can also use a "bit reservoir", a partially full frame's ability to hold part of the next frame's audio data, allowing temporary changes in effective bitrate, even in a constant bitrate stream. Internal handling of the bit reservoir increases encoding delay.[citation needed]


What kind of audio is required to use a bit reservoir?


What is a possible result of handling the bit reservoir?


A bit reservoir allows for what kind of changes in effective bit rate?


A large benefit of a bit reservoir is that you can use it even while encoding what kind of stream?


What can scale factor band 21 be shortened to?

There is no scale factor band 21 (sfb21) for frequencies above approx 16 kHz, forcing the encoder to choose between less accurate representation in band 21 or less efficient storage in all bands below band 21, the latter resulting in wasted bitrate in VBR encoding.


What is the maximum frequency that scale factor band 21 can go up to?


The encoder has to choose between less acurate representation in band 21 or which factor in all bands below band 21?


What does less efficient storage result in for VBR encoding?


What is a section of a file that contains metadeta referred to as?

A "tag" in an audio file is a section of the file that contains metadata such as the title, artist, album, track number or other information about the file's contents. The MP3 standards do not define tag formats for MP3 files, nor is there a standard container format that would support metadata and obviate the need for tags.


What else can metadeta contain other than the title, artist or track number?


What would be needed to support metadata and obviate the need for tags?


Other than the ID3v1, which similar standard format for tag exists?

However, several de facto standards for tag formats exist. As of 2010, the most widespread are ID3v1 and ID3v2, and the more recently introduced APEv2. These tags are normally embedded at the beginning or end of MP3 files, separate from the actual MP3 frame data. MP3 decoders either extract information from the tags, or just treat them as ignorable, non-MP3 junk data.


What is the most recently introduced standard for tag formatting?


What is the second place in a file that tags are normally stored, with the first being at the beginning?


What is important to note about where the tags are stored?


If the MP3 decoders do not extract information from the tags, what do they do to them?


What is the name given to the standard for measure and storing the loudness of an MP3 file?

ReplayGain is a standard for measuring and storing the loudness of an MP3 file (audio normalization) in its metadata tag, enabling a ReplayGain-compliant player to automatically adjust the overall playback volume for each file. MP3Gain may be used to reversibly modify files based on ReplayGain measurements so that adjusted playback can be achieved on players without ReplayGain capability.


What is measuring and storing loudness of an MP3 file also known as?


What does the standard ReplayGain allow a player to automatically adjust?


What program can be used to modify files based on ReplayGain measurements?


MP3Gain is important because it allows players without what capability to have adjusted playback?


Where is the basic MP3 decoding and technology patent free?

The basic MP3 decoding and encoding technology is patent-free in the European Union, all patents having expired there. In the United States, the technology will be substantially patent-free on 31 December 2017 (see below). The majority of MP3 patents expired in the US between 2007 and 2015.

When will the technology be patent - free in the United States?


Between which years did most of the MP3 patents in the US expire?


What has many organizations claiming ownership of patents related to aspects of MP3 led to?

In the past, many organizations have claimed ownership of patents related to MP3 decoding or encoding. These claims led to a number of legal threats and actions from a variety of sources. As a result, uncertainty about which patents must be licensed in order to create MP3 products without committing patent infringement in countries that allow software patents was a common feature of the early stages of adoption of the technology.


Legal threats and confusion made it difficult to ensure what about patents regarding MP3 products?


What was the danger of not correctly patenting products?


At what stage of the technology were these problems prevalent?


What became publicly available on 6 December 1991?

The initial near-complete MPEG-1 standard (parts 1, 2 and 3) was publicly available on 6 December 1991 as ISO CD 11172. In most countries, patents cannot be filed after prior art has been made public, and patents expire 20 years after the initial filing date, which can be up to 12 months later for filings in other countries. As a result, patents required to implement MP3 expired in most countries by December 2012, 21 years after the publication of ISO CD 11172.


When can patents not be filed in most countries?


How long does it take for patents to expire after being filed?


How long can it take for patents to be approved after initially being filed?


When did patents required to implement MP3 expire in most countries?


How long does it take for patents to expire in the United States?

An exception is the United States, where patents filed prior to 8 June 1995 expire 17 years after the publication date of the patent, but application extensions make it possible for a patent to issue much later than normally expected (see submarine patents). The various MP3-related patents expire on dates ranging from 2007 to 2017 in the U.S. Patents filed for anything disclosed in ISO CD 11172 a year or more after its publication are questionable. If only the known MP3 patents filed by December 1992 are considered, then MP3 decoding has been patent-free in the US since 22 September 2015 when U.S. Patent 5,812,672 expired which had a PCT filing in October 1992. If the longest-running patent mentioned in the aforementioned references is taken as a measure, then the MP3 technology will be patent-free in the United States on 30 December 2017 when U.S. Patent 5,703,999, held by the Fraunhofer-Gesellschaft and administered by Technicolor, expires.


A patent issue much later than normally expected can be referred to as what?


What year is the latest that MP3 related patents will expire on in the United States?

What are Technicolor constantly in the process of doing?


When did the Fraunhofer institute send out a letter?

In September 1998, the Fraunhofer Institute sent a letter to several developers of MP3 software stating that a license was required to "distribute and/or sell decoders and/or encoders". The letter claimed that unlicensed products "infringe the patent rights of Fraunhofer and Thomson. To make, sell and/or distribute products using the [MPEG Layer-3] standard and thus our patents, you need to obtain a license under these patents from us."


What did the letter claim would be required to distribute and/or sell decoders and/or encoders?


What does selling unlicensed products mean that the seller is doing?


What can products not use if they want to avoid infringing on patent rights?


Who was sued for patent infringement on MP3 technology?

Sisvel S.p.A. and its U.S. subsidiary Audio MPEG, Inc. previously sued Thomson for patent infringement on MP3 technology, but those disputes were resolved in November 2005 with Sisvel granting Thomson a license to their patents. Motorola followed soon after, and signed with Sisvel to license MP3-related patents in December 2005. Except for three patents, the US patents administered by Sisvel had all expired in 2015, however (the exceptions are: U.S. Patent 5,878,080, expires February 2017, U.S. Patent 5,850,456, expires February 2017 and U.S. Patent 5,960,037, expires 9.

What did German officials seize from SanDisk on September 2006?

In September 2006, German officials seized MP3 players from SanDisk's booth at the IFA show in Berlin after an Italian patents firm won an injunction on behalf of Sisvel against SanDisk in a dispute over licensing rights. The injunction was later reversed by a Berlin judge, but that reversal was in turn blocked the same day by another judge from the same court, "bringing the Patent Wild West to Germany" in the words of one commentator.

Which company allegedly inherited MP3 patents from AT&T-Bell LAbs?

Alcatel-Lucent has asserted several MP3 coding and compression patents, allegedly inherited from AT&T-Bell Labs, in litigation of its own. In November 2006, before the companies' merger, Alcatel sued Microsoft for allegedly infringing seven patents. On 23 February 2007, a San Diego jury awarded Alcatel-Lucent US $1.52 billion in damages for infringement of two of them. The court subsequently tossed the award, however, finding that one patent had not been infringed and that the other was not even owned by Alcatel-Lucent; it was co-owned by AT&T and Fraunhofer, who had licensed it to Microsoft, the judge ruled. That defense judgment was upheld on appeal in 2008. See Alcatel-Lucent v. Microsoft for more information.

AAC, mp3PRO and MP2 are all members of the same technological family as which other lossy format?

Other lossy formats exist. Among these, mp3PRO, AAC, and MP2 are all members of the same technological family as MP3 and depend on roughly similar psychoacoustic models. The Fraunhofer Gesellschaft owns many of the basic patents underlying these formats as well, with others held by Dolby Labs, Sony, Thomson Consumer Electronics, and AT&T.

Which company owns many of the patents that cover the other formats?


Opus and Vorbis are two explans of what kind of compression format?

There are also open compression formats like Opus and Vorbis that are available free of charge and without any known patent restrictions. Some of the newer audio compression formats, such as AAC, WMA Pro and Vorbis, are free of some limitations inherent to the MP3 format that cannot be overcome by any MP3 encoder.


Being open formats means that Opus and Vorbis can be used without what?

What city did House music originate from?

House music is a genre of electronic dance music that originated in Chicago in the early 1980s. It was initially popularized in Chicago, circa 1984. House music quickly spread to other American cities such as Detroit, New York City, and Newark – all of which developed their own regional scenes. In the mid-to-late 1980s, house music became popular in Europe as well as major cities in South America, and Australia. Early house music commercial success in Europe saw songs such as "Pump Up The Volume" by MARRS (1987), "House Nation" by House Master Boyz and the Rude Boy of House (1987), "Theme from S'Express" by S'Express (1988) and "Doctorin' the House" by Coldcut (1988) in the pop charts. Since the early to mid-1990s, house music has been infused in mainstream pop and dance music worldwide.

House music is characterized by what type of beats?

Early house music was generally dance-based music characterized by repetitive 4/4 beats, rhythms mainly provided by drum machines, off-beat hi-hat cymbals, and synthesized basslines. While house displayed several characteristics similar to disco music, it was more electronic and minimalistic, and the repetitive rhythm of house was more important than the song itself. House music in the 2010s, while keeping several of these core elements, notably the prominent kick drum on every beat, varies widely in style and influence, ranging from the soulful and atmospheric deep house to the more minimalistic microhouse. House music has also fused with several other genres creating fusion subgenres, such as euro house, tech house, electro house and jump house.

When was the second wave of progressive house?

In the late 1980s, many local Chicago house music artists suddenly found themselves presented with major label deals. House music proved to be a commercially successful genre and a more mainstream pop-based variation grew increasingly popular. Artists and groups such as Madonna, Janet Jackson, Paula Abdul, Aretha Franklin, Bananarama, Diana Ross, Tina Turner, Whitney Houston, Steps, Kylie Minogue, Bjork, and C+C Music Factoryhave all incorporated the genre into some of their work. After enjoying significant success in the early to mid-90s, house music grew even larger during the second wave of progressive house (1999–2001). The genre has remained popular and fused into other popular subgenres, for example, G-house, Deep House, Tech House and Bass House. As of 2015, house music remains extremely popular in both clubs and in the mainstream pop scene while retaining a foothold on underground scenes across the globe.[citation needed]

Soul and disco influenced house music, plus mixing and editing techniques earlier explored by disco, garage music and post-disco DJs, producers, and audio engineers such as Walter Gibbons, Tom Moulton, Jim Burgess, Larry Levan, Ron Hardy, M & M, and others who produced longer, more repetitive, and percussive arrangements of existing disco recordings. Early house producers such as Frankie Knuckles created similar compositions from scratch, using samplers, synthesizers, sequencers, and drum machines.

Rachel Cain, co-founder of an influential Trax Records, was previously involved in the burgeoning punk scene and cites industrial and post-punk record store Wax Trax! Records as an important connection between the ever-changing underground sounds of Chicago. As most proto-house DJs were primarily stuck to playing their conventional ensemble of dance records, Frankie Knuckles and Ron Hardy, two influential pioneers of house music, were known for their out-of-bounds behavior. The former, credited as "the Godfather of House," worked primarily with early disco music with a hint of new and different music (whether it was post-punk or post-disco) but still enjoying a variety of music, while the latter produced unconventional DIY mixtapes which he later played straight-on in the music club Muzic Box, boiling with raw energy. Marshall Jefferson, who would later appear with the Chicago house classic "Move Your Body (The House-Music Anthem)," (originally released on Chicago-based Trax Records) got involved in house music after hearing Ron Hardy's music in Muzic Box.

who were the chicago radio jocks that played dance music in the early 1980s?

In the early 1980s, Chicago radio jocks The Hot Mix 5, and club DJs Ron Hardy and Frankie Knuckles played various styles of dance music, including older disco records (mostly Philly disco and Salsoul tracks), electro funk tracks by artists such as Afrika Bambaataa, newer Italo disco, B-Boy hip hop music by Man Parrish, Jellybean Benitez, Arthur Baker, and John Robie, and electronic pop music by Kraftwerk and Yellow Magic Orchestra. Some made and played their own edits of their favorite songs on reel-to-reel tape, and sometimes mixed in effects, drum machines, and other rhythmic electronic instrumentation. In this era,

who produced the song "on and on" in 1984?

The hypnotic electronic dance song "On and On", produced in 1984 by Chicago DJ Jesse Saunders and co-written by Vince Lawrence, had elements that became staples of the early house sound, such as the Roland TB-303 bass synthesizer and minimal vocals as well as a Roland (specifically TR-808) drum machine and Korg (specifically Poly-61) synthesizer. It also utilized the bassline from Player One's disco record "Space Invaders" (1979). "On and On" is sometimes cited as the 'first house record', though other examples from around that time, such as J.M. Silk's "Music is the Key" (1985), have also been cited.

when was jesse saunders' "on and on" a hit?

Starting in 1984, some of these DJs, inspired by Jesse Saunders' success with "On and On", tried their hand at producing and releasing original compositions. These compositions used newly affordable electronic instruments to emulate not just Saunders' song, but the edited, enhanced styles of disco and other dance music they already favored. These homegrown productions were played on Chicago-area radio and in local discothèques catering mainly to African-American and gay audiences. By 1985, although the exact origins of the term are debated, "house music" encompassed these locally produced recordings. Subgenres of house, including deep house and acid house, quickly emerged and gained traction.

Deep house's origins can be traced to Chicago producer Mr Fingers's relatively jazzy, soulful recordings "Mystery of Love" (1985) and "Can You Feel It?" (1986). According to author Richie Unterberger, it moved house music away from its "posthuman tendencies back towards the lush" soulful sound of early disco music.

When was Phuture's "Acid Tracks" released?

Acid house arose from Chicago artists' experiments with the squelchy Roland TB-303 bass synthesizer, and the style's origins on vinyl is generally cited as Phuture's "Acid Tracks" (1987). Phuture, a group founded by Nathan "DJ Pierre" Jones, Earl "Spanky" Smith Jr., and Herbert "Herb J" Jackson, is credited with having been the first to use the TB-303 in the house music context. The group's 12-minute "Acid Tracks" was recorded to tape and was played by DJ Ron Hardy at the Music Box, where Hardy was resident DJ. Hardy once played it four times over the course of an evening until the crowd responded favorably. The track also utilized a Roland TR-707 drum machine.

what radio station aired the Hot Mix 5 show?

Club play from pioneering Chicago DJs such as Hardy and Lil Louis, local dance music record shops such as Importes, State Street Records, Loop Records, Gramaphone Records and the popular Hot Mix 5 shows on radio station WBMX-FM helped popularize house music in Chicago. Later, visiting DJs & producers from Detroit fell into the genre. Trax Records and DJ International Records, Chicago labels with wider distribution, helped popularize house music inside and outside of Chicago. One 1986 house tune called "Move Your Body" by Marshall Jefferson, taken from the appropriately titled "The House Music Anthem" EP, became a big hit in Chicago and eventually worldwide. By 1986, UK labels were releasing house music by Chicago acts, and by 1987 house tracks by Chicago DJs and producers were appearing on and topping the UK music chart. By this time, house music released by Chicago-based labels was considered a must-play in clubs.

what club did the term 'house music' originate from?

The term "house music" is said to have originated from a Chicago club called The Warehouse, which existed from 1977 to 1983. Clubbers to The Warehouse were primarily black and gay, who came to dance to music played by the club's resident DJ Frankie Knuckles, whom fans refer to as the "godfather of house". After the Warehouse closed in 1983, the crowds went to Knuckles' new club, The Power Plant. In the Channel 4 documentary Pump Up The Volume, Knuckles remarks that the first time he heard the term "house music" was upon seeing "we play house music" on a sign in the window of a bar on Chicago's South Side. One of the people in the car with him joked, "you know, that's the kind of music you play down at the Warehouse!", and then everybody laughed. South-Side Chicago DJ Leonard "Remix" Roy, in self-published statements, claims he put such a sign in a tavern window because it was where he played music that one might find in one's home; in his case, it referred to his mother's soul & disco records, which he worked into his sets. Farley Jackmaster Funk was quoted as saying "In 1982, I was DJing at a club called The Playground and there was this kid named Leonard 'Remix' Roy who was a DJ at a rival club called The Rink. He came over to my club one night, and into the DJ booth and said to me, 'I've got the gimmick that's gonna take all the people out of your club and into mine – it's called House music.' Now, where he got that name from or what made him think of it I don't know, so the answer lies with him."

what is the name of Chip E's 1985 house hit?

Chip E.'s 1985 recording "It's House" may also have helped to define this new form of electronic music. However, Chip E. himself lends credence to the Knuckles association, claiming the name came from methods of labeling records at the Importes Etc. record store, where he worked in the early 1980s: bins of music that DJ Knuckles played at the Warehouse nightclub were labelled in the store "As Heard At The Warehouse", which was shortened to simply "House". Patrons later asked for new music for the bins, which Chip E. implies was a demand the shop tried to meet by stocking newer local club hits.

who ran the D.J. International record label?

In a 1986 interview, Rocky Jones, the former club DJ who ran the D.J. International record label, doesn't mention Importes Etc., Frankie Knuckles, or the Warehouse by name, but agrees that "house" was a regional catch-all term for dance music, and that it was once synonymous with older disco music.


House is a regional catch-all term for what kind of music?


what was 'house music' once synonymous with?


Larry Heard, a.k.a. "Mr. Fingers", claims that the term "house" became popular due to many of the early DJs creating music in their own homes using synthesizers and drum machines such as the Roland TR-808, TR-909, and the TB 303.[citation needed] These synthesizers were used to create a house subgenre called acid house.


what are the Roland TR-808, TR-909, and TB 303 examples of?


synthesizers were used to create what house subgenre?


Juan Atkins, an originator of Detroit techno music, claims the term "house" reflected the exclusive association of particular tracks with particular clubs and DJs; those records helped differentiate the clubs and DJs, and thus were considered to be their "house" records. In an effort to maintain such exclusives, the DJs were inspired to create their own "house" records.


What did Atkins claim the term house reflected?


Why were DJs inspired to create their own house records?


Who did House relay political messages to?

House also had an influence of relaying political messages to people who were considered to be outcasts of society. The music appealed to those who didn't fit into mainstream American society and was especially celebrated by many black males. Frankie Knuckles once said that the Warehouse club in Chicago was like "church for people who have fallen from grace" The house producer Marshall Jefferson compared it to "old-time religion in the way that people just get happy and screamin'". Deep house was similar to many of the messages of freedom for the black community.

what was one of the earliest Detroit techno hits?

Detroit techno is an offshoot of Chicago house music. It was developed starting in the late 80s, one of the earliest hits being "Big Fun" by Inner City. Detroit techno developed as the legendary disc jockey The Electrifying Mojo conducted his own radio program at this time, influencing the fusion of eclectic sounds into the signature Detroit techno sound. This sound, also influenced by European electronica (Kraftwerk, Art of Noise), Japanese synthpop (Yellow Magic Orchestra), early B-boy Hip-Hop (Man Parrish, Soul Sonic Force) and Italo disco (Doctor's Cat, Ris, Klein M.B.O.), was further pioneered by Juan Atkins, Derrick May, and Kevin Saunderson, the "godfathers" of Detroit Techno.[citation needed]

"MAYDAY" and Thomas Barnett released "Nude Photo" in 1987 on May's label "Transmat Records", which helped kickstart the Detroit techno music scene and was put in heavy rotation on Chicago's Hot Mix 5 Radio DJ mix show and in many Chicago clubs.[citation needed] A year later, Transmat released what was to become one of techno and house music's classic anthems – the seminal track "Strings of Life". Transmat Records went on to have many more successful releases[citation needed] such as 1988's "Wiggin". As well, Derrick May had successful[citation needed] releases on Kool Kat Records and many remixes for a host of underground and mainstream recording artist.

Kevin Saunderson's company KMS Records contributed many releases that were as much house music as they were techno. These tracks were well received in Chicago and played on Chicago radio and in clubs.[citation needed] Blake Baxter's 1986 recording, "When we Used to Play / Work your Body", 1987's "Bounce Your Body to the Box" and "Force Field", "The Sound / How to Play our Music" and "the Groove that Won't Stop" and a remix of "Grooving Without a Doubt". In 1988, as house music became more popular among general audiences, Kevin Saunderson's group Inner City with Paris Gray released the 1988 hits "Big Fun" and "Good Life", which eventually were picked up by Virgin Records. Each EP / 12 inch single sported remixes by Mike "Hitman" Wilson and Steve "Silk" Hurley of Chicago and Derrick "Mayday" May and Juan Atkins of Detroit. In 1989, KMS had another hit release of "Rock to the Beat" which was a theme in Chicago dance clubs.[citation needed]

Early British house music quickly set itself apart from the original Chicago house sound;[citation needed] many of the early hits were based on sample montage, rap was often used for vocals (far more than in the US),[citation needed] and humor was frequently an important element.

what tiny island was house music also being devloped on?

But house was also being developed on Ibiza,[citation needed] although no house artists or labels were coming from this tiny island at the time. By the mid-1980s a distinct Balearic mix of house was discernible.[citation needed] Several clubs such as Amnesia with DJ Alfredo were playing a mix of rock, pop, disco and house. These clubs, fueled by their distinctive sound and Ecstasy, began to have an influence on the British scene. By late 1987, DJs such as Trevor Fung, Paul Oakenfold and Danny Rampling were bringing the Ibiza sound to UK clubs such as the Haçienda in Manchester, and in London clubs such as Shoom in Southwark, Heaven, Future and Spectrum.

In Chicago, Marshall Jefferson had formed the house group Ten City Byron Burke, Byron Stingily & Herb Lawson(from "intensity"). New York–based performers such as Mateo & Matos and Blaze had slickly produced disco house tracks.

"Techno-Scratch" was released by the Knights Of The Turntable in 1984 which had a similar techno sound to Cybotron. The manager of the Factory nightclub and co-owner of the Haçienda, Tony Wilson, also promoted acid house culture on his weekly TV show. The Midlands also embraced the late 1980s house scene with illegal parties and more legal dance clubs such as The Hummingbird.

what was a top club for house music in new york city?

Back in America the scene had still not progressed beyond a small number of clubs in Chicago, Detroit, Newark and New York City. However, many independent Chicago-based record labels were making appearances on the Dance Chart with their releases. In the UK, any house song released by a Chicago-based label was routinely considered a must play at many clubs playing house music. Paradise Garage in New York City was still a top club. The emergence of Todd Terry, a pioneer of the genre, was important in America. His cover of Class Action's Larry Levan mixed "Weekend" demonstrated the continuum from the underground disco to a new house sound with hip-hop influences evident in the quicker sampling and the more rugged bass-line.

In the late 1980s, Nu Groove Records prolonged, if not launched the careers of Rheji Burrell & Rhano Burrell, collectively known as Burrell (after a brief stay on Virgin America via Timmy Regisford and Frank Mendez), along with basically every relevant DJ and Producer in the NY underground scene. The Burrell's are responsible for the "New York Underground" sound and are the undisputed champions of this style of house. Their 30+ releases on this label alone seems to support that fact. In today's market Nu Groove Record releases like the Burrells' enjoy a cult-like following and mint vinyl can fetch $100 U.S. or more in the open market.

what is the oldest dance club in america?

By the late 80s, House had moved West, particularly to San Francisco, Oakland, Los Angeles, Fresno, San Diego and Seattle. Los Angeles saw a huge explosion of underground raves and DJs, notably DJs Marques Wyatt and Billy Long, who spun at Jewel's Catch One, the oldest dance club in America. In 1989, the L.A. based, former EBN-OZN singer/rapper Robert Ozn started indie house label One Voice Records, releasing the Mike "Hitman" Wilson remix of Dada Nada's "Haunted House," which garnered instant club and mix show radio play in Chicago, Detroit and New York as well as in the U.K. and France. The record shot up to Number Five on the Billboard Club Chart, marking it as the first House record by a white artist to chart in the U.S. Dada Nada, the moniker for Ozn's solo act, released in 1990, what has become a classic example of jazz-based Deep House, the Frankie Knuckles and David Morales remix of Dada Nada's "Deep Love" (One Voice Records/US, Polydor/UK), featuring Ozn's lush, crooning vocals and muted trumpet improvisational solos, underscoring Deep House's progression into a genre that integrated jazz and pop songwriting structures – a feature which continued to set it apart from Acid House and Techno.

Another U.S. hit which received radio play was the single "Time for the Perculator" by Cajmere, which became the prototype of ghetto house subgenre. Cajmere started the Cajual and Relief labels (amongst others). By the early 1990s artists such as Cajmere himself (under that name as well as Green Velvet and as producer for Dajae), DJ Sneak, Glenn Underground and others did many recordings. The 1990s saw new Chicago house artists emerge such as DJ Funk, who operates a Chicago house record label called Dance Mania. Ghetto house and acid house were other house music styles that were also started in Chicago.

where did the "chilling out" concept develop?

In Britain, further experiments in the genre boosted its appeal. House and rave clubs such as Lakota and Cream emerged across Britain, hosting house and dance scene events. The 'chilling out' concept developed in Britain with ambient house albums such as The KLF's Chill Out and Analogue Bubblebath by Aphex Twin. The Godskitchen superclub brand also began in the midst of the early 90's rave scene. After initially hosting small nights in Cambridge and Northampton, the associated events scaled up in Milton Keynes, Birmingham and Leeds. A new indie dance scene also emerged in the 90's. In New York, bands such as Deee-Lite furthered house's international influence. Two distinctive tracks from this era were the Orb's "Little Fluffy Clouds" (with a distinctive vocal sample from Rickie Lee Jones) and the Happy Mondays' "Wrote for Luck" ("WFL") which was transformed into a dance hit by Vince Clarke.

what act was passed in england in an attempt to ban large rave dance events?

In England, one of the few licensed venues The Eclipse attracted people from up and down the country as it was open until the early hours. The Criminal Justice and Public Order Act 1994 was a government attempt to ban large rave dance events featuring music with "repetitive beats". There were a number of abortive "Kill the Bill" demonstrations. The Spiral Tribe at Castle Morten was probably the nail in the coffin for illegal raves, and forced through the bill, which became law, in November 1994. The music continued to grow and change, as typified by Leftfield with "Release the Pressure", which introduced dub and reggae into the house sound, although Leftfield had prior releases, such as "Not Forgotten" released in 1990 on Sheffield's Outer Rhythm records.

where was a new type of club called Cream located?

A new generation of clubs such as Liverpool's Cream and the Ministry of Sound were opened to provide a venue for more commercial sounds. Major record companies began to open "superclubs" promoting their own acts. These superclubs entered into sponsorship deals initially with fast food, soft drinks, and clothing companies. Flyers in clubs in Ibiza often sported many corporate logos. A new subgenre, Chicago hard house, was developed by DJs such as Bad Boy Bill, DJ Lynnwood, DJ Irene, Richard "Humpty" Vission and DJ Enrie, mixing elements of Chicago house, funky house and hard house together. Additionally, Producers such as George Centeno, Darren Ramirez, and Martin O. Cairo would develop the Los Angeles Hard House sound. Similar to gabber or hardcore techno from the Netherlands, this sound was often associated with the "rebel" culture of the time. These 3 producers are often considered "ahead of their time" since many of the sounds they engineered during the late 20th century became more prominent during the 21st century.

Daft Punk began producing a new sound out of what european city?

Towards the end of the 1990s and into the 2000s, producers such as Daft Punk, Stardust, Cassius, St. Germain and DJ Falcon began producing a new sound out of Paris's house scene. Together, they laid the groundwork for what would be known as the French house movement. By combining the harder-edged-yet-soulful philosophy of Chicago house with the melodies of obscure funk, state-of-the-art production techniques and the sound of analog synthesizers, they began to create the standards that would shape all house music.

Chicago Mayor Richard M. Daley proclaimed August 10, 2005 to be "House Unity Day" in Chicago, in celebration of the "21st anniversary of house music" (actually the 21st anniversary of the founding of Trax Records, an independent Chicago-based house label). The proclamation recognized Chicago as the original home of house music and that the music's original creators "were inspired by the love of their city, with the dream that someday their music would spread a message of peace and unity throughout the world". DJs such as Frankie Knuckles, Marshall Jefferson, Paul Johnson and Mickey Oliver celebrated the proclamation at the Summer Dance Series, an event organized by Chicago's Department of Cultural Affairs.

Defected Records was at the forefront of what type of house music?

It was during this decade that vocal house became firmly established, both in the underground and as part of the pop market, and labels such as Defected Records, Roule and Om were at the forefront of championing the emerging sound. In the mid-2000s, fusion genres such as electro house and fidget house emerged.[citation needed] This fusion is apparent in the crossover of musical styles by artists such as Dennis Ferrer and Booka Shade, with the former's production style having evolved from the New York soulful house scene and the latter's roots in techno.

What was different about swedish progressive house music?

2010s saw multiple new sounds in house music developed by numerous DJs. Sweden knew a prominence of snare-less "Swedish progressive house" with the emergence of Sebastian Ingrosso, Axwell, Steve Angello (These three formed a trio called Swedish House Mafia), Avicii, Alesso, etc. Netherlands brought together a concept of "Dirty Dutch", electro house subgenre characterized by very abrasive leads and darker arpeggios, with prominent DJs Chuckie, Hardwell, Laidback Luke, Afrojack, R3hab, Bingo Players, Quintino, Alvaro, Cedric Gervais, 2G, etc. Elsewhere, fusion genres derivative of 2000s progressive house returned to prominence, especially with the help of DJs Calvin Harris, Eric Prydz, Mat Zo, Above & Beyond and Fonzerelli in Europe, Deadmau5, Kaskade, Steve Aoki, Porter Robinson and Wolfgang Gartner in the US and Canada. The growing popularity of such artists led to the emergence of electro house and progressive house blended sounds in popular music, such as singles Lady Gaga's "Marry the Night", The Black Eyed Peas' "The Best One Yet (The Boy)" and the will.i.am and Britney Spears "Scream & Shout". Big room house found increasing popularity since 2010, particularly through international dance music festivals such as Tomorrowland, Ultra Music Festival, and Electric Daisy Carnival.

The terms uppercase and lowercase originated from the common layout which type of drawers?

The terms upper case and lower case can be written as two consecutive words, connected with a hyphen (upper-case and lower-case), or as a single word (uppercase and lowercase). These terms originated from the common layouts of the shallow drawers called type cases used to hold the movable type for letterpress printing. Traditionally, the capital letters were stored in a separate case that was located above the case that held the small letters, and the name proved easy to remember since capital letters are taller.

What is the basis of capitalization standards for the sentence-style capitalization?

The convention followed by many British publishers (including scientific publishers, like Nature, magazines, like The Economist and New Scientist, and newspapers, like The Guardian and The Times) and U.S. newspapers is to use sentence-style capitalisation in headlines, where capitalisation follows the same rules that apply for sentences. This convention is usually called sentence case. It may also be applied to publication titles, especially in bibliographic references and library catalogues. Examples of global publishers whose English-language house styles prescribe sentence-case titles and headings include the International Organization for Standardization.

Which century did the lower-case script for the Greek Alphabet originate?

Similar developments have taken place in other alphabets. The lower-case script for the Greek alphabet has its origins in the 7th century and acquired its quadrilinear form in the 8th century. Over time, uncial letter forms were increasingly mixed into the script. The earliest dated Greek lower-case text is the Uspenski Gospels (MS 461) in the year 835.[citation needed] The modern practice of capitalising the first letter of every sentence seems to be imported (and is rarely used when printing Ancient Greek materials even today).

In orthography and typography, what is the distinction between the letters that are in larger upper case and lower upper case

In orthography and typography, letter case (or just case) is the distinction between the letters that are in larger upper case (also capital letters, capitals, caps, large letters, or more formally majuscule, see Terminology) and smaller lower case (also small letters, or more formally minuscule, see Terminology) in the written representation of certain languages. Here is a comparison of the upper and lower case versions of each letter included in the English alphabet (the exact representation will vary according to the font used):


Minuscule is a term uses to describe which case of letter?


Capital letters refer to which case of letter?


Letter case is used to distinction betweem lowercase and uppercase letter in which common representation of certain languages?


Capitalization in English is universally standardized for which type of writing?

Capitalisation in English, in terms of the general orthographic rules independent of context (e.g. title vs. heading vs. text), is universally standardized for formal writing. (Informal communication, such as texting, instant messaging or a handwritten sticky note, may not bother, but that is because its users usually do not expect it to be formal.) In English, capital letters are used as the first letter of a sentence, a proper noun, or a proper adjective. There are a few pairs of words of different meanings whose only difference is capitalisation of the first letter. The names of the days of the week and the names of the months are also capitalised, as are the first-person pronoun "I" and the interjection "O" (although the latter is uncommon in modern usage, with "oh" being preferred). Other words normally start with a lower-case letter. There are, however, situations where further capitalisation may be used to give added emphasis, for example in headings and titles (see below). In some traditional forms of poetry, capitalisation has conventionally been used as a marker to indicate the beginning of a line of verse independent of any grammatical feature.

Originally alphabets were written entirely in which type of letter?

Originally alphabets were written entirely in majuscule letters, spaced between well-defined upper and lower bounds. When written quickly with a pen, these tended to turn into rounder and much simpler forms. It is from these that the first minuscule hands developed, the half-uncials and cursive minuscule, which no longer stayed bound between a pair of lines. These in turn formed the foundations for the Carolingian minuscule script, developed by Alcuin for use in the court of Charlemagne, which quickly spread across Europe. The advantage of the minuscule over majuscule was improved, faster readability.[citation needed]

What is often prescribed by the grammar of a language or by conventions of a particular discipline?

Letter case is often prescribed by the grammar of a language or by the conventions of a particular discipline. In orthography, the uppercase is primarily reserved for special purposes, such as the first letter of a sentence or of a proper noun, which makes the lowercase the more common variant in text. In mathematics, letter case may indicate the relationship between objects with uppercase letters often representing "superior" objects (e.g. X could be a set containing the generic member x). Engineering design drawings are typically labelled entirely in upper-case letters, which are easier to distinguish than lowercase, especially when space restrictions require that the lettering be small.

Engineering design drawings typically utiilze which case of letter in labeling?


Why are uppercase letters preferred often times when space is restricted?


Who do majuscules have which distinguish themselves from minuscules?

Typographically, the basic difference between the majuscules and minuscules is not that the majuscules are big and minuscules small, but that the majuscules generally have the same height. The height of the minuscules varies, as some of them have parts higher or lower than the average, i.e. ascenders and descenders. In Times New Roman, for instance, b, d, f, h, k, l, t are the letters with ascenders, and g, j, p, q, y are the ones with descenders. Further to this, with old-style numerals still used by some traditional or classical fonts—although most do have a set of alternative Lining Figures— 6 and 8 make up the ascender set, and 3, 4, 5, 7 and 9 the descender set.


In Time New Roman the letter "b" would be consider which type of letter based on whether it is above or below average height?


Descending letters tend to have a part which falls where relative to the average height of a letter?


Besides the number 6, which number makes of the ascender set in some traditional or classical fonts?


What do most Western languages use in their written form to add clarity?

Most Western languages (particularly those with writing systems based on the Latin, Cyrillic, Greek, Coptic, and Armenian alphabets) use letter cases in their written form as an aid to clarity. Scripts using two separate cases are also called bicameral scripts. Many other writing systems make no distinction between majuscules and minuscules – a system called unicameral script or unicase. This includes most syllabic and other non-alphabetic scripts. The Georgian alphabet is special since it used to be bicameral, but today is mostly used in a unicameral way.

Papyri from Herculaneum dating before 79 AD have been to to be written in which hand writing?

In Latin, papyri from Herculaneum dating before 79 AD (when it was destroyed) have been found that have been written in old Roman cursive, where the early forms of minuscule letters "d", "h" and "r", for example, can already be recognised. According to papyrologist Knut Kleve, "The theory, then, that the lower-case letters have been developed from the fifth century uncials and the ninth century Carolingian minuscules seems to be wrong." Both majuscule and minuscule letters existed, but the difference between the two variants was initially stylistic rather than orthographic and the writing system was still basically unicameral: a given handwritten document could use either one style or the other but these were not mixed. European languages, except for Ancient Greek and Latin, did not make the case distinction before about 1300.[citation needed]

What is capitalization of significant words applied to in the United States besides titles?

As regards publication titles it is, however, a common typographic practice among both British and U.S. publishers to capitalise significant words (and in the United States, this is often applied to headings, too). This family of typographic conventions is usually called title case. For example, R. M. Ritter's Oxford Manual of Style (2002) suggests capitalising "the first word and all nouns, pronouns, adjectives, verbs and adverbs, but generally not articles, conjunctions and short prepositions". This is an old form of emphasis, similar to the more modern practice of using a larger or boldface font for titles. The rules for which words to capitalise are not based on any grammatically inherent correct/incorrect distinction and are not universally standardized; they are arbitrary and differ between style guides, although in most styles they tend to follow a few strong conventions, as follows:


Capitalization of significant words refers to which family of typographic conventions?

The use of bold fonts and capilization in titles falls under which unusual grammatical distinction?


Attempts to unify Latin, Greek, and Cyrillic would create which sort of problems?

As briefly discussed in Unicode Technical Note #26, "In terms of implementation issues, any attempt at a unification of Latin, Greek, and Cyrillic would wreak havoc [and] make casing operations an unholy mess, in effect making all casing operations context sensitive […]". In other words, while the shapes of letters like A, B, E, H, K, M, O, P, T, X, Y and so on are shared between the Latin, Greek, and Cyrillic alphabets (and small differences in their canonical forms may be considered to be of a merely typographical nature), it would still be problematic for a multilingual character set or a font to provide only a single codepoint for, say, uppercase letter B, as this would make it quite difficult for a wordprocessor to change that single uppercase letter to one of the three different choices for the lower-case letter, b (Latin), β (Greek), or в (Cyrillic). Without letter case, a "unified European alphabet" – such as ABБCГDΔΕZЄЗFΦGHIИJ…Z, with an appropriate subset for each language – is feasible; but considering letter case, it becomes very clear that these alphabets are rather distinct sets of symbols.

What was the name of the nomad tribes that hunted bison?

During the 14th century in the northeastern part of the state nomad tribes by the name of Jornado hunted bison along the Rio Grande; they left numerous rock paintings throughout the northeastern part of the state. When the Spanish explorers reached this area they found their descendants, Suma and Manso tribes. In the southern part of the state, in a region known as Aridoamerica, Chichimeca people survived by hunting, gathering, and farming between AD 300 and 1300. The Chichimeca are the ancestors of the Tepehuan people.


The Chichimeca are the ancestors of what people?


What was the name of the town in which Miguel Hidalgo y Costilla declared independence?

During the Napoleonic Occupation of Spain, Miguel Hidalgo y Costilla, a Catholic priest of progressive ideas, declared Mexican independence in the small town of Dolores, Guanajuato on September 16, 1810 with a proclamation known as the "Grito de Dolores". Hidalgo built a large support among intellectuals, liberal priests and many poor people. Hidalgo fought to protect the rights of the poor and indigenous population. He started on a march to the capital, Mexico City, but retreated back north when faced with the elite of the royal forces at the outskirts of the capital. He established a liberal government from Guadalajara, Jalisco but was soon forced to flee north by the royal forces that recaptured the city. Hidalgo attempted to reach the United States and gain American support for Mexican independence. HIdalgo reached Saltillo, Coahuila where he publicly resigned his military post and rejected a pardon offered by Viceroy Francisco Venegas in return for Hidalgo's surrender. A short time later, he and his supporters were captured by royalist Ignacio Elizondo at the Wells of Baján (Norias de Baján) on March 21, 1811 and taken to the city of Chihuahua. Hidalgo forced the Bishop of Valladolid, Manuel Abad y Queipo, to rescind the excommunication order he had circulated against him on September 24, 1810. Later, the Inquisition issued an excommunication edict on October 13, 1810 condemning Miguel Hidalgo as a seditionary, apostate, and heretic.

Who did Santa Anna order the reinstatement as comandante general?

At a convention of citizens called to select a new provisional ruler, Gutierrez obtained the vote, with P. J. Escalante for his deputy, and a council to guide the administration. Santa Anna ordered the reinstatement of Mendarozqueta as comandante general. Gutiérrez yielded, but Escalante refused to surrender office, demonstrations of support ensued, but Escalante yielded when troops were summoned from Zacatecas. A new election brought a new legislature, and conforming governors. In September 1835 José Urrea a federalist army officer came into power.

What was the name of the treaty that ended the war?

The Treaty of Guadalupe Hidalgo, signed on February 2, 1848, by American diplomat Nicholas Trist and Mexican plenipotentiary representatives Luis G. Cuevas, Bernardo Couto, and Miguel Atristain, ended the war, gave the U.S. undisputed control of Texas, and established the U.S.–Mexican border of the Rio Grande. As news of peace negotiations reached the state, new call to arms began to flare among the people of the state. But as the Mexican officials in Chihuahua heard that General Price was heading back to Mexico with a large force comprising several companies of infantry and three companies of cavalry and one division of light artillery from Santa Fe on February 8, 1848, Ángel Trías sent a message to Sacramento Pass to ask for succession of the area as they understood the war had concluded. General Price, misunderstanding this as a deception by the Mexican forces, continued to advance towards the state capital. On March 16, 1848 Price began negotiations with Ángel Trías, but the Mexican leader responded with an ultimatum to General Price. The American forces engaged with the Mexican forces near Santa Cruz de los Rosales on March 16, 1848. The Battle of Santa Cruz de los Rosales was the last battle of the Mexican–American War and it occurred after the peace treaty was signed. The American forces maintained control over the state capital for three months after the confirmation of the peace treaty. The American presence served to delay the possible succession of the state which had been discussed at the end of 1847, and the state remained under United States occupation until May 22, 1848.

In consequence to the Reform War, the federal government was bankrupt and could not pay its foreign debts to Spain, England, and France. On July 17, 1861, President Juárez decreed a moratorium on payment to foreign debtors for a period of two years. Spain, England, and France did not accept the moratorium by Mexico; they united at the Convention of the Triple Alliance on October 31, 1861 in which they agreed to take possession of several custom stations within Mexico as payment. A delegation of the Triple Alliance arrived in Veracruz in December 1861. President Juárez immediately sent his Foreign Affairs Minister, Manuel Doblado, who is able to reduce the debts through the Pacto de Soledad (Soledad Pact). General Juan Prim of Spain persuaded the English delegation to accept the terms of the Pacto de Soledad, but the French delegation refused.

Who was deeply dissatisfied with Bazaine's decision to abandon Chihuahua?

Maximilian was deeply dissatisfied with General Bazaine's decision to abandon the state capital of Chihuahua and immediately ordered Agustín B. Billaut to recapture the city. On December 11, 1865, Billaut with a force of 500 men took control of the city. By January 31, 1866 Billaut was ordered to leave Chihuahua, but he left behind 500 men to maintain control. At the zenith of their power, the imperialist forces controlled all but four states in Mexico; the only states to maintain strong opposition to the French were: Guerrero, Chihuahua, Sonora, and Baja California.

After the death of the president Benito Juárez in 1872, the first magistracy of the country was occupied by the vice-president Sebastián Lerdo de Tejada, who called for new elections. Two candidates were registered; Lerdo de Tejada and General Porfirio Díaz, one of the heroes of the Battle of Puebla which had taken place on May 5, 1862. Lerdeo de Tejada won the election, but lost popularity after he announced his intent to run for re-election. On March 21, 1876, Don Porfirio Díaz rebelled against President Sebastian Lerdo de Tejada. The Plan of Tuxtepec defended the "No Re-election" principle. On June 2, 1876 the garrisons in the state of Chihuahua surrendered to the authority of General Porfirio Díaz; Governor Antonio Ochoa was arrested until all the Lerdista forces were suppressed throughout the state. Porfirio Díaz then helped Tíras regain the governorship of the state of Chihuahua allowing for the Plan of Tuxtepec to be implemented. The victory of the Plan of Tuxtepec, gave the interim presidency to Jose Maria Iglesias and later, as the only candidate, the General Porfirio Díaz assumed the presidency on May 5, 1877. During the first years of the Porfiriato (Porfirio Díaz Era), the Díaz administration had to combat several attacks from the Lerdista forces and the Apache. A new rebellion led by the Lerdista party was orchestrated from exile in the United States. The Lerdista forces were able to temporarily occupy the city of El Paso del Norte until mid-1877. During 1877 the northern parts of the state suffered through a spell of extreme drought which were responsible for many deaths in El Paso del Norte.

In March 1912, in Chihuahua, Gen. Pascual Orozco revolted. Immediately President Francisco Madero commanded Gen. Victoriano Huerta of the Federal Army, to put down the Orozco revolt. The governor of Chihuahua mobilized the state militia led by Colonel Pancho Villa to supplement General Huerta. By June, Villa notified Huerta that the Orozco revolt had been put down and that the militia would consider themselves no longer under Huerta's command and would depart. Huerta became furious and ordered that Villa be executed. Raúl Madero, Madero's brother, intervened to save Villa's life. Jailed in Mexico City, Villa fled to the United States. Madero's time as leader was short-lived, ended by a coup d'état in 1913 led by Gen. Victoriano Huerta; Orozco sided with Huerta, and Huerta made him one of his generals.


Who notified Huerta the revolt had been put down?


Which state has more forests than Chihuahua?

Although Chihuahua is primarily identified with the Chihuahuan Desert for namesake, it has more forests than any other state in Mexico, with the exception of Durango. Due to its variant climate, the state has a large variety of fauna and flora. The state is mostly characterized by rugged mountainous terrain and wide river valleys. The Sierra Madre Occidental mountain range, an extension of the Rocky Mountains, dominates the state's terrain and is home to the state's greatest attraction, Las Barrancas del Cobre, or Copper Canyon, a canyon system larger and deeper than the Grand Canyon. On the slope of the Sierra Madre Occidental mountains (around the regions of Casas Grandes, Cuauhtémoc and Parral), there are vast prairies of short yellow grass, the source of the bulk of the state's agricultural production. Most of the inhabitants live along the Rio Grande Valley and the Conchos River Valley.

Public opinion pressured the U.S. government to bring Villa to justice for the raid on Columbus, New Mexico; U.S. President Wilson sent Gen. John J. Pershing and some 5,000 troops into Mexico in an unsuccessful attempt to capture Villa. It was known as the Punitive Expedition. After nearly a year of pursuing Villa, American forces returned to the United States. The American intervention had been limited to the western sierras of Chihuahua. Villa had the advantage of intimately knowing the inhospitable terrain of the Sonoran Desert and the almost impassable Sierra Madre mountains and always managed to stay one step ahead of his pursuers. In 1923 Villa was assassinated by a group of seven gunmen who ambushed him while he was sitting in the back seat of his car in Parral.


How long did the American troops pursue Villa?


Along which mountain range does the Cave of Windows lie?

La Cueva De Las Ventanas (The Cave of Windows), a series of cliff dwellings along an important trade route, and Las Jarillas Cave scrambled along the canyons of the Sierra Madre in Northwestern Chihuahua date between AD 1205 and 1260 and belong to the Paquimé culture. Cuarenta Casas is thought to have been a branch settlement from Paquime to protect the trade route from attack. Archaeologists believe the civilization began to decline during the 13th century and by the 15th century the inhabitants of Paquime sought refuge in the Sierra Madre Occidental while others are thought to have emigrated north and joined the Ancestral Pueblo peoples. According to anthropologist current natives tribes (Yaqui, Mayo, Opata, and Tarahumara) are descendants of the Casas Grandes culture.
