converting .wav file to .ogg in javascript

Question

I\'m trying to capture user\'s audio input from the browser. I have done it with WAV but the files are really big. A friend of mine told me that OGG files are much smaller. Does

This question has been driving me crazy because I haven't seen anyone come up with a really clean solution, so I came up with my own library:

https://github.com/sb2702/audioRecord.js

Basic usage

audioRecord.requestDevice(function(recorder){
  // Request user permission for microphone access

      recorder.record(); // Start recording

      recorder.stop();  /Stop recording

      recorder.exportOGG(function(oggBlob){
        //Here's your OGG file
      });

      recorder.exportMP3(function(mp3Blob){
               //Here's your mp3 file
      });

      recorder.exportWAV(function(wavBlob){
            //Here's your WAV file
      });

});

Using the continuous mp3 encoding option, it's entirely reasonable to capture and encode audio input entirely in the browser, cross-browser, without a server or native code.

It's still rough around the edges, but I'll try to clean / fix it up.
