LC3PCMBuffersize()

uint16_t LC3PCMBuffersize	(	uint16_t	sampleRate,
		uint8_t	bitDepth,
		LC3FrameSize_t	frameSize,
		int32_t *	result
	)

#include <lc3/codec/inc/LC3API.h>

Calculates the buffer size required for PCM data.

Returns the minimum buffer size in bytes needed to hold a frame of PCM data for the specified sample rate and bit depth. A bitDepth value in the range (16,24] uses a 3 byte/sample PCM output while (24,32] uses 4 bytes/sample.

Parameters

[in]	sampleRate	Sample rate.
[in]	bitDepth	Bit depth of generated PCM data.
[in]	frameSize	Frame size of 7.5 or 10 msec.
[out]	result	Pointer to an LC3 Return Code integer.

Returns

PCM buffer size on success or 0 on error.
