Detailed Description

Calibration Utility for Voice Detector

. Using this audio processor, you can calibrate the IVoiceDetector.Threshold.

Constructor & Destructor Documentation

VoiceDetectorCalibration()

VoiceDetectorCalibration	(	IVoiceDetector	voiceDetector,
		ILevelMeter	levelMeter,
		int	samplingRate,
		int	channels
	)

Create new VoiceDetectorCalibration instance.

Parameters

voiceDetector	Voice Detector to calibrate.
levelMeter	Level Meter to look at for calibration.
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	Optional callback that is called after calibration is complete.

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)
