0.5 / f actually, which is extraextraordinary. Both Joern and I have invited the original poster to explain more clearly what he wants to achieve. Because as it stands his question doesn't make sense and can't be answered. If the purpose of this list is to let people help each other with audio software related problems, then the other replies so far are, to put it gently, 'unfortunate'. To put some things right: - Absolute phase response *does* matter. It's quite easy to create e.g. a filter that has a perfectly flat amplitude response, modifies only the phase, and sounds as a e.g. a resonance or even a reverb. You won't hear the relatively harmless phase response of a tyipcal amp, but that doesn't mean you can't hear phase errors in general. - Phase is related to delay but it is not the same thing. Group delay is again something different. Mixing up all these is not going to help anyone understand things any better.
