Detailed Description

Decoder for the noise component (stochastic component) of the signal.

Constructor & Destructor Documentation

NoiseDecoder::NoiseDecoder	(	double	orig_mix_freq,
		double	mix_freq,
		size_t	block_size
	)

Creates a noise decoder object.

Parameters

orig_mix_freq	original mix freq (sample rate) of the audio file that was encoded
mix_freq	mix freq (sample rate) of the output sample data

Member Function Documentation

void NoiseDecoder::process	(	const AudioBlock &	audio_block,
		float *	samples,
		OutputMode	output_mode = REPLACE
	)

This function decodes the noise contained in the frame and fills the decoded_residue vector of the frame.

Parameters

audio_block

AudioBlock to be decoded
