Audio-ISSUE-38 (setTargetValueAtTime): AudioParam.setTargetValueAtTime is misleading and underdefined [Web Audio API] http://www.w3.org/2011/audio/track/issues/38 Raised by: Philip Jägenstedt On product: Web Audio API The naming of this function is misleading, since it does not in fact set the target value at the given time. timeConstant is underdefined, what is the exponent? A "first-order filter (exponential)" is mentioned, but not clarified further. Finally, it is not well defined what the difference to exponentialRampToValueAtTime is, but we suspect that setTargetValueAtTime is something like v=1-e-kt. The equations involving the 3 parameters should be included in the spec, normatively.
