Contact emails rt...@chromium.org,hong...@chromium.org Spec http://webaudio.github.io/web-audio-api/

Summary Support the copyFromChannel and copyToChannel methods on a WebAudio AudioBuffer Motivation This is a required part of the WebAudio spec that Chrome currently does not support. These methods make reading and writing the contents of an AudioBuffer easier. Compatibility Risk Firefox: Shipped Internet Explorer: No public signals Safari: No public signals Web developers: No signals

These methods are new and upward compatible. This brings Chrome in line with the current WebAudio specification for AudioBuffers

Ongoing technical constraints None Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? Yes or no. Yes.
