Syntax

class FEarlyReflectionsFast

Remarks

Basic implementation of early reflections using a predelay, low pass filter and feedback delay network (FDN). The FDN utilizes four delay lines where each delay line consists of an all pass filter and low pass filter to control diffusion and absorption.

Constructors
