/*! \class PRCRev
|
|
\brief Perry's simple reverberator class.
|
|
|
|
This class is based on some of the famous
|
|
Stanford/CCRMA reverbs (NRev, KipRev), which
|
|
were based on the Chowning/Moorer/Schroeder
|
|
reverberators using networks of simple allpass
|
|
and comb delay filters. This class implements
|
|
two series allpass units and two parallel comb
|
|
filters.
|
|
|
|
by Perry R. Cook and Gary P. Scavone, 1995 - 2005.
