Member Function Documentation

calc_peak()

float AudioGrapher::LoudnessReader::calc_peak	(	float	target_lufs = -23,
		float	target_dbtp = -1
	)		const

get_loudness()

bool AudioGrapher::LoudnessReader::get_loudness	(	float *	integrated,
		float *	short_term = NULL,
		float *	momentary = NULL
	)		const

process()

virtual void AudioGrapher::LoudnessReader::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 >.

Reimplemented in AudioGrapher::Analyser.

reset()

void AudioGrapher::LoudnessReader::reset
