/*! \class JCRev
|
|
\brief John Chowning's reverberator class.
|
|
|
|
This class is derived from the CLM JCRev
|
|
function, which is based on the use of
|
|
networks of simple allpass and comb delay
|
|
filters. This class implements three series
|
|
allpass units, followed by four parallel comb
|
|
filters, and two decorrelation delay lines in
|
|
parallel at the output.
|
|
|
|
by Perry R. Cook and Gary P. Scavone, 1995 - 2005.
