Detailed Description

This class handles conversion of audio data (audio_chunk) to various linear PCM types, with optional dithering.

Reimplemented from service_base.

virtual void audio_postprocessor::run	(	const audio_chunk &	p_chunk,
		mem_block_container &	p_output,
		t_uint32	p_out_bps,
		t_uint32	p_out_bps_physical,
		bool	p_dither,
		audio_sample	p_prescale
	)			`[pure virtual]`

Processes one chunk of audio data.

Parameters:

	p_chunk	Chunk of audio data to process.
	p_output	Receives output linear signed PCM data.
	p_out_bps	Desired bit depth of output.
	p_out_bps_physical	Desired physical word width of output. Must be either 8, 16, 24 or 32, greater or equal to p_out_bps. This is typically set to same value as p_out_bps.
	p_dither	Indicates whether dithering should be used. Note that dithering is CPU-heavy.
	p_prescale	Value to scale all audio samples by when converting. Set to 1.0 to do nothing.
