Audio-ISSUE-92 (AudioBufferSourceNodeResampling): AudioBufferSourceNode resampling [Web Audio API]

http://www.w3.org/2011/audio/track/issues/92

Raised by: Philip J├Ągenstedt
On product: Web Audio API

AudioBufferSourceNode has a playbackRate attribute which will require interpolation/resampling of some kind. However, it is not defined how to resample. Possibly it should be as close as possible to an ideal resampling, in which case that should be stated. Alternatively, it could be possible to specify which kind of resampling to perform via an attribute: nearest, linear, cubic, sinc, etc...

It also needs to be defined what should be done about folding when the net result of the sample rates and playback rate is a downsampling, if anything.
