Answer 2

The ideal solution would be getUserMedia and the Stream API. Unfortunately, it is currently not well-supported across modern browsers. As of June 14, 2012 the only browser confirmed to have support according to caniuse.com is Chrome 21. Others appear to be working on solid implementations.

Until native support arrives, Flash can access and record both audio and video.

The most efficient free-ish solution bandwidth-wise is probably to develop a Flash app that streams Speex data to a Flash Media Server (e.g. Red5/Wowza). It's a huge pain though.

A far simpler solution is to stream raw audio over a standard HTTP post. This can be done in Flash without a proprietary media server:

If you need MP3 on the server-side you can transcode using lame.
