mediaLib Library Functions    mlib_SignalADPCM2Bits2Linear(3MLIB)



NAME
     mlib_SignalADPCM2Bits2Linear - adaptive  differential  pulse
     code modulation (ADPCM)

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlib_status mlib_SignalADPCM2Bits2Linear(mlib_s16 *pcm,
          const mlib_u8 *adpcm, void *state, mlib_s32 n);


DESCRIPTION
     The mlib_SignalADPCM2Bits2Linear() function  performs  adap-
     tive  differential  pulse code modulation (ADPCM) in compli-
     ance with the ITU (former CCITT)  G.721,  G.723,  and  G.726
     specifications.  It converts data from G.723 or G.726 16kbps
     2-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.

ATTRIBUTES
     See attributes(5) for descriptions of the  following  attri-
     butes:
