Is what you are looking for a resonant comb filter? I.e. a delay line with a resonant frequency which "rings"? Check the archives for the "resonant comb filter series" thread. Me, Davide Morelli and Ian Smith-Heisters worked out a bunch of stuff there. I wouldn't know off-hand how to convert a band pass filter to a comb filter, though. I only how to do it with delay lines right now. Some Googling on filter theory could fix that pretty fast, though...

Hi, I have a simple patch with a [click~] object connected to a [reson~] filter. I'd like to know how it is possible to convert the bandwith parameter of the filter to decay lenght (in milliseconds). In SuperCollider there is a particular version of the "resonz" filter called "ringz", here is the description: Ringz.ar(in, freq, decaytime, mul, add)
