/*! \class NRev
|
|
\brief CCRMA's NRev reverberator class.
|
|
|
|
This class is derived from the CLM NRev
|
|
function, which is based on the use of
|
|
networks of simple allpass and comb delay
|
|
filters. This particular arrangement consists
|
|
of 6 comb filters in parallel, followed by 3
|
|
allpass filters, a lowpass filter, and another
|
|
allpass in series, followed by two allpass
|
|
filters in parallel with corresponding right
|
|
and left outputs.
