At high gains, the allpasses have a 'grainy' or 'ringy' sound to them with impulses. It doesn't sound allpass but it measures that way.
Should I be changing the feedback gains on the allpasses based on the allpass length or size? |
How are you modulating the taps? How many taps do you have. What is your tap spacing in msecs?
An allpass is flat. The ringing comes from the frequency dependent delay of an allpass. So some frequencies stick around longer than others. This is particularly noticable at higher RTs because the same signal goes through the same allpass multiple times. If you can change the allpass before the same signal hits it again, then the ringing can be reduced.
Generally longer allpasses will ring more because they have longer delay vs frequency times. So reducing the gain on larger allpasses is useful.
