Member Function Documentation

init()

void AudioGrapher::DemoNoiseAdder::init	(	samplecnt_t	max_samples,
		samplecnt_t	interval,
		samplecnt_t	duration,
		float	level
	)

process()

void AudioGrapher::DemoNoiseAdder::process ( ProcessContext< float > const &  context )

virtual

Process given data. The data can not be modified, so in-place processing is not allowed. At least this function must be implemented by deriving classes

Implements AudioGrapher::Sink< float >.
