<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>Perry's simple reverberator class. </p>
<p>This class takes a monophonic input signal and produces a stereo output signal. It is based on some of the famous Stanford/CCRMA reverbs (<a class="el" href="classstk_1_1NRev.html" title="CCRMA&#39;s NRev reverberator class.">NRev</a>, 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.</p>
