bench.wasm

Benchmark the performance of whisper.cpp in the browser using WebAssembly

Link: https://ggml.ai/whisper.cpp/bench.wasm/

Terminal version: examples/bench

Build instructions

# build using Emscripten (v3.1.2)
git clone https://github.com/ggerganov/whisper.cpp
cd whisper.cpp
mkdir build-em && cd build-em
emcmake cmake ..
make -j

The example can then be started by running a local HTTP server:

python3 examples/server.py

And then opening a browser to the following URL: http://localhost:8000/bench.wasm

To run the example in a different server, you need to copy the following files to the server's HTTP path:

# copy the produced page to your HTTP path
cp bin/bench.wasm/*       /path/to/html/
cp bin/libbench.js        /path/to/html/
cp bin/libbench.worker.js /path/to/html/

📝 Note: As of Emscripten 3.1.58 (April 2024), separate worker.js files are no longer generated and the worker is embedded in the main JS file. So the worker file will not be geneated for versions later than 3.1.58.
