Comment from Chris Rogers, 19 May 2012:

Agreed, there are several nuances relating to this. 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
