NAME

mlib_SignalADPCM2Bits2Linear - adaptive differential pulse code modulation (ADPCM)  

SYNOPSIS

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

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

 

DESCRIPTION

The mlib_SignalADPCM2Bits2Linear() 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 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.
