* 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)
|
|
