For example, if the delay value is a sinusoid (AudioNode connected to AudioParam) or an even a linear ramp (linearRampToValueAtTime), what must happen? If the value changes fast enough, does the sound play backwards?

There are several interpolation approaches (linear, cubic, sinc) and also whether to interpolate delay changes using a "doppler" approach where the delay times are interpolated, or if the interpolation is a "cross-fade" interpolation. EA has asked for the "cross-fade" technique in addition to what I consider to be the standard "doppler" technique. I have no strong opinion if we should include the "cross-fade" approach right now, or hold that technique off for a later version of the spec (where we can add an .interpolationTechnique attribute (which will default to the standard "doppler") thus remaining backwards-compatible 113936 2 olivier.thereaux 2014-10-28 17:14:35 +0000 Web Audio API issues have been migrated to Github.
