mediaLib Library Functions    mlibSignalADPCM5Bits2Linear(3MLIB)



NAME
     mlibSignalADPCM5Bits2Linear - adaptive  differential  pulse
     code modulation (ADPCM)

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

     mlibstatus mlibSignalADPCM5Bits2Linear(mlibs16 *pcm,
          const mlibu8 *adpcm, void *state, mlibs32 n);


DESCRIPTION
     The mlibSignalADPCM5Bits2Linear() function  performs  adap-
     tive  differential  pulse code modulation (ADPCM) in compli-
     ance with the ITU (former CIT)  G.721,  G.723,  and  G.726
     specifications.  It  converts data fromG.723 or G.726 40kbps
     5-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 MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.

ATRIBUTES
     See attributes(5) for descriptions of the  following  attri-
