javascript - Recording html5 audio

Question

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.webkitGetUserMedia || navigator.getUserMedia; navigator.getUserMedia({audio: true}, gotAudio, noStream);

This then prompts the user to allow audio recording, and if you say "yes" a message appears saying that chrome is recording. However is it possible to access the audio buffer with the raw data in it? I don't seem to be able to find out how. There are suggested specs that havn't been implemented yet does anyone know if it can actually be done on any browser now, and provide instructions?

Answer 1

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.
