I am working on a project called AudioRecorder that exactly fits your needs. You can find it here. https://github.com/dbieber/audiorecorder.

This builds upon the already mentioned emscripten compiled speex codec: jpemartins/speex.js.

If you already have the audio and just want to encode it, call Codec.encode(samples). You can also use AudioRecorder to record the audio -- there's an example on Github here: http://dbieber.github.io/audiorecorder/examples/recorder.html

The implementation currently assumes 1-channel audio and if you want two channel you can just encode or decode twice.
