I'm interested in messing with some structures suggested by Julian Parker's work on spring reverb emulation. https://acris.aalto.fi/ws/portalfiles/portal/13004391/art_10.1155_2011_646134.pdf
This paper suggests an "interpolating all-pass delay". Initially, I don't think I would care about modulating these in real time, but of course, everything is better with envelope modulation so I'd probably try that eventually. The library includes a handful of all passes and of course I can try all of them, but wondering if a particular one would be particularly swell for this kind of thing. https://faustcloud.grame.fr/doc/libraries/index.html#thiran-allpass-interpolation https://faustcloud.grame.fr/doc/libraries/index.html#fi.allpass_comb https://faustcloud.grame.fr/doc/libraries/index.html#fi.allpass_fcomb https://faustcloud.grame.fr/doc/libraries/index.html#fi.allpass_fcomb5-and-fi.allpass_fcomb1a Note that I did some experiments in the past with this sort of thing on a Spin FV-1 and found that chirp block lengths in the 12 to 20 samples range (at 32768 Hz fs) seemed to work well for this sort of thing. However, the FV-1 doesn't have enough instructions to generate a very long chirp. I am really looking to emphasize the dispersion "chirp" in this particular exercise. Thanks! GW
