NAME
       mlib_SignalADPCM4Bits2Linear - adaptive differential pulse code modulation (ADPCM)

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

       mlib_status mlib_SignalADPCM4Bits2Linear(mlib_s16 *pcm,
	    const mlib_u8 *adpcm, void *state, mlib_s32 n);

DESCRIPTION
       The mlib_SignalADPCM4Bits2Linear() 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 fromG.721 or G.726 32kbps 4-bit ADPCM to 16-bit linear PCM format.

PARAMETERS
       The function takes the following arguments:

       pcm	Linear PCM sample array.

       adpcm	ADPCM code 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.
