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.
Does anyone have a code example for this type of filter?
An IIR allpass filter where the unit delay is replaced
with a much longer delay, ie tens, hundreds or even thousands
of samples.
Would this result in some kind of reverb type effect as Fons suggested?
I'm looking for a way to adjust the phase of a signal rather than the
amplitude. Does such a plugin already exist? If not which ladspa plugin
would be the most suitable to start from?
I've looked at using parts of jamin and librubberband but there may be a
faster to implement option available.
