Audio-ISSUE-42 (AudioParamSampling): AudioParam sampling is undefined [Web Audio API]

http://www.w3.org/2011/audio/track/issues/42

Raised by: Philip Jägenstedt
On product: Web Audio API

It is not defined how the AudioParam values (ramps or AudioNode input) are sampled. These approaches would yield hugely different results:

 * Sample-and-hold at the beginning of each processing buffer (if they exist in the implementation).
 * Correct downsampling with low pass filtering to below the Nyquist frequency for each processing buffer. This could turn a 20KHz signal into silence.
 * Continuously per audio sample at the mixing level. Slow?
