Tone detection functions

The following functions enable and disable detectors of precise tones, raw energy, and silence:

Function	Synchronous/ Asynchronous	Description
adiStartToneDetector	Asynchronous	Starts a precise tone detector.
adiStopToneDetector	Asynchronous	Stops a precise tone detector.
adiStartEnergyDetector	Asynchronous	Starts the energy detector (energy versus silence).
adiStopEnergyDetector	Asynchronous	Stops the energy detector (energy versus silence).
