Function Documentation

gcc_pure ConstBuffer<int16_t> pcm_convert_to_16	(	PcmBuffer &	buffer,
		PcmDither &	dither,
		SampleFormat	src_format,
		ConstBuffer< void >	src
	)

Converts PCM samples to 16 bit.

If the source format is 24 bit, then dithering is applied.

Parameters

buffer	a PcmBuffer object
dither	a PcmDither object for 24-to-16 conversion
src	the source PCM buffer

Returns

the destination buffer

gcc_pure ConstBuffer<int32_t> pcm_convert_to_24	(	PcmBuffer &	buffer,
		SampleFormat	src_format,
		ConstBuffer< void >	src
	)

Converts PCM samples to 24 bit (32 bit alignment).

Parameters

buffer	a PcmBuffer object
src	the source PCM buffer

Returns

the destination buffer

gcc_pure ConstBuffer<int32_t> pcm_convert_to_32	(	PcmBuffer &	buffer,
		SampleFormat	src_format,
		ConstBuffer< void >	src
	)

Converts PCM samples to 32 bit.

Parameters

buffer	a PcmBuffer object
src	the source PCM buffer

Returns

the destination buffer

gcc_pure ConstBuffer<float> pcm_convert_to_float	(	PcmBuffer &	buffer,
		SampleFormat	src_format,
		ConstBuffer< void >	src
	)

Converts PCM samples to 32 bit floating point.

Parameters

buffer	a PcmBuffer object
src	the source PCM buffer

Returns

the destination buffer
