NAME

       mlib_SignalALaw2Linear - ITU G.711 m-law and A-law compression and decompression

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_SignalALaw2Linear(mlib_s16 *pcm, const mlib_u8 *acode,
	    mlib_s32 n);

DESCRIPTION

       The  mlib_SignalALaw2Linear()  function performs ITU G.711 m-law and A-law compression and decompression in compliance with the ITU (Former
       CCITT) G.711 specification.

PARAMETERS

       The function takes the following arguments:

       pcm	Linear PCM sample array.

       acode	A-law code array.

       n	Number of samples in the source array.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.

NAME

       mlib_SignalLinear2ADPCM3Bits - adaptive differential pulse code modulation (ADPCM)

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_SignalLinear2ADPCM3Bits(mlib_u8 *adpcm,
	    const mlib_s16 *pcm, void *state, mlib_s32 n);

DESCRIPTION

       The mlib_SignalLinear2ADPCM3Bits() function performs adaptive differential pulse code modulation (ADPCM) in compliance with the ITU (former
       CCITT) G.721, G.723, and G.726 specifications. It converts data from 16-bit linear PCM to G.723 or G.726 24kbps 3-bit ADPCM format.

PARAMETERS

       The function takes the following arguments:

       adpcm	ADPCM code array.

       pcm	Linear PCM sample array.

       state	Internal structure of the codec.

       n	Number of samples in the source array.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
