/*
 * AudioMultiply_F32
 *
 * Created: Patrick Radius, December 2016
 * Purpose: Multiply two channels of audio data. Can be used for example as 'vca' or amplitude modulation.
 * Assumes floating-point data.
 *
 * This processes a single stream fo audio data (ie, it is mono)
 *
 * NOTE: *** This is functionally the same clss as AudioMathMultiply_F32  ***
 * Both classes are continued for back compatibility.  Use ofAudioMathMultiply_F32
 * is preferred.  We need to pick one.
 *
 * MIT License.  use at your own risk.
