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?
