process()

void switchboard::NoiseGate::process	(	const float *	input,
		float *	output,
		const uint	numberOfFrames )

Processes the audio buffer and applies the noise gate.

Parameters

input	Interleaved stereo input audio buffer
output	Interleaved stereo output audio buffer
numberOfFrames	The number of frames to process.

setAttackTimeSeconds()

void switchboard::NoiseGate::setAttackTimeSeconds

(

const float

attackTimeSeconds

)

Sets the volume envelope filter attack time in seconds. Minimum value: 0.0f Maximum value: 0.5f.

Parameters

attackTimeSeconds

The new attack time in seconds.

setCloseThresholdDB()

void switchboard::NoiseGate::setCloseThresholdDB

(

Parameters

holdTimeSeconds

The new hold time in seconds.

setOpenThresholdDB()

void switchboard::NoiseGate::setOpenThresholdDB

(

const float

openThreshold

)

Sets the noise gate opening threshold in decibels.

When the signal raises above this threshold value the noise gate opens. Minimum: -96.0f Maximum: 24.0f

Parameters

openThreshold

The new open threshold value.

setReleaseTimeSeconds()

void switchboard::NoiseGate::setReleaseTimeSeconds

(

const float
