Hello, I've been reading about various variable delay effects and reverbs recently, and as I don't understand the math and sometimes not even the terminology, I feel a bit lost. E.g. https://ccrma.stanford.edu/realsimple/DelayVar/Flanging.html https://ccrma.stanford.edu/realsimple/DelayVar/Phasing_First_Order_Allpass_F... https://ccrma.stanford.edu/realsimple/DelayVar/Phasing_2nd_Order_Allpass_Fil... https://ccrma.stanford.edu/realsimple/Reverb/A_Schroeder_Reverberator_called... As far as I can tell ChucK doesn't have some of the primitives (1st or 2nd order allpass filters, feedforward comb-filters, multitap delay) necessary for implementing these, just the STK implementations such as JCRev. I have an approximation here https://github.com/heuermh/lick/blob/master/lick/effect/APF.ck and used it here https://github.com/heuermh/lick/blob/master/lick/effect/LoopReverb.ck It seems to be doing something reverb-ish but I'm not sure what the APF delay values should be. Can anyone point me in the right direction (to code and/or reading material)? Thanks, michael
