OpenAudio_ArduinoLibrary/AudioSwitch_OA_F32.h

/*
 * AudioSwitch_F32.h
 * 
 * AudioSwitch4
 * Created: Chip Audette, OpenAudio, April 2019
 * Purpose: Switch one input to 4 outputs, which should only trigger one of the 4
 *      audio processing paths (therebys saving computation on paths that you don't
 *      care about).
 * Assumes floating-point data.
 * From Tympan Library, to OpenAudio_ArduinoLibrary June 2020, add 8 position class.
 *          
 * This processes a single stream of audio data (ie, it is mono)       
 *          
 * MIT License.  use at your own risk.
