Schroeder-Moorer reverberator for Max/MSP (bpatcher)
Schroeder-Moorer reverberator (also called Freeverb) is a well tuned reverb designed by four cascaded Schroeder allpass filters and eight parallel Schroeder-Moorer lowpass feedback comb-filters (LBCF). Indeed, the LBCF uses filtered feedback; by allocating the one-pole filter inside the comb filter, instead of just a feedback gain.
This reverberator is now available as bpatcher/abstraction for Max/MSP and all filters have been designed in Gen~ environment.
• These reverberator and filters are adapted from Julius O. Smith III, 2010.
