Is it possible to record sound with html5 yet? I have downloaded the latest canary version of chrome and use the following code:
navigator.getUserMedia = navigator.w
Webkit and Chrome audio API's support recording, however as their API's evolve it will be difficult to maintain code that uses them.
An active open-source project named Sink.js allows recording and also allows you to push raw samples: https://github.com/jussi-kalliokoski/sink.js/. Since the project is pretty active they have been able to keep on top of changes in Webkit and Chrome as they come out.
