Detailed Description

Utility Audio Processor Voice Detection Calibration.

Encapsulates level meter, voice detector and voice detector calibrator in single instance.

Constructor & Destructor Documentation

VoiceLevelDetectCalibrate()

VoiceLevelDetectCalibrate	(	int	samplingRate,
		int	channels
	)

Create new VoiceLevelDetectCalibrate instance

Parameters

samplingRate	Sampling rate of the audio signal (in Hz).
channels	Number of channels in the audio signal.

Member Function Documentation

Calibrate()

void Calibrate	(	int	durationMs,
		Action< float >	onCalibrated = null
	)

Start calibration

Parameters

durationMs	Duration of the calibration procedure (in milliseconds).
onCalibrated	Called when calibration is complete. Parameter is new threshold value.

This activates the Calibration process. It will reset the given LevelMeter's AccumAvgPeakAmp (accumulated average peak amplitude), and when the duration has passed, use it for the VoiceDetector's detection threshold.

Process()

T [] Process

(

T[]

buf

)

Process a frame of data.

Parameters

buf	Buffer containing input data

Returns

Buffer containing output data or null if frame has been discarded (VAD)

Implements IProcessor< T >.
