Member Function Documentation

float Async::AudioAmp::gain

(

void

)

const [inline]

Read the gain.

Returns:

Return the gain in dB

Definition at line 135 of file AsyncAudioAmp.h.

void Async::AudioAmp::processSamples	(	float *	dest,
		const float *	src,
		int	count
	)			[inline, protected, virtual]

Process incoming samples and put them into the output buffer.

Parameters:

	dest	Destination buffer
	src	Source buffer
	count	Number of samples in the source buffer

This function should be reimplemented by the inheriting class to do the actual processing of the incoming samples. All samples must be processed, otherwise they are lost and the output buffer will contain garbage.

Implements Async::AudioProcessor.

void Async::AudioAmp::setGain

(

float

gain_db

)

[inline]

Set the gain to use.

Parameters:

gain_db

The gain given in dB
