Andy, A reverb is not simply a "network of delays", in fact most digital reverbs consist of a loop of allpass filters* set to various delay lengths with a variety of injection points and output taps. * An allpass filter is defined as a feedforward delay combined with a feedback delay, it is at the heart of every digital reverb and the result of increasing the coefficient is greater diffusion. -Chuck >Charles Zwicky wrote: >>I love how "granular" processing has become such a catch-all in the >>electronic music community.. ;-) >> >>The "freeze" pedal uses hi coefficient allpass filters, it's >>similar to a digital reverb set to an infinite decay time. > >I've not heard the term "hi coefficient" used in filter dsp before. > >As a reverb is a network of delays with feedback I don't >disagree with your analysis of course. >Except that the sound isn't reverb-like. > > >There's clearly a repetition every 180mS here > >http://www.youtube.com/watch?v=sjFth1mg5Rc > >from 2:48 > >but then there's longer cycles audible too. > >...but there's no glissandi within the freeze >...however, unlike a reverbed glissando there's > still clearly defined constant frequencies > >need to hear it without Youtube sound compression, >but I'm still puzzled > >andy -- ... http://www.zmix.net http://www.esession.com/ChuckZwicky http://albumcredits.com/zmix
