I'm working on a project that requires audio data to be streamed via HTTP to/from server.

We need to compress the audio data using SPEEX.

In Flash, we can use Alchemy and LibSpeex, but how can we do it in JavaScript. HTML5 can be used.

Thanks.

I recently implemented a successful HTML5/VOIP client using the following JS port of Speex, truly awesome stuff:

For now you'll need to either wait for MediaStreamRecorder or jump the gun like I did, and make use of this:

As for how you piece the whole lot together into a slick system, your call :)

Hope i've helped
