A component for encoding PCM data to Ogg Vorbis in the browser

#iago

Module for encoding Ogg in the browser.

• Stream to the encoder--your compressed audio is ready when the recording is finished
• Uses a web worker for the actual compression; UI thread is free

iago.getBlob().then(function(blob) {
  // blob is of type audio/ogg
});

Are you going to keep developing iago or libvorbis.js ? So far, these are the most advanced open source projects for encoding OGG in JS.
