ALawToLin

Decodes the 8-bit A-law encoded samples to linear samples.

Syntax

IppStatus ippsALawToLin_8u16s(const Ipp8u* pSrc, Ipp16s* pDst, int len);

IppStatus ippsALawToLin_8u32f(const Ipp8u* pSrc, Ipp32f* pDst, int len);

Parameters

pSrc	Pointer to the source vector.
pDst	Pointer to the destination vector.
len	Number of samples in the vector.

Description

The function ippsALawToLin is declared in the ipps.h file. This function decodes the 8-bit A-law encoded samples in the vector pSrc to PCM-linear samples and stores them in the vector pDst. Code example shows how to use the function ippsALawToLin_8u32f.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when the pDst or pSrc pointer is NULL.
ippStsSizeErr	Indicates an error when len is less than or equal to 0.
