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.
