Re: is it possible to render audio into a file?

Hi Andy,

I think you want this:

https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html#OfflineAudioContext-section

The OfflineAudioContext object (accessible as "webkitOfflineAudioContext" in Chrome) allows you to asynchronously render any graph into an AudioBuffer. The encoding step into an audio format isn't supported by Web Audio yet AFAIK but it's easy to write a WAV encoder using typed arrays.
