mlib_SignalLinear2ADPCM4Bits - adaptive differential pulse code modulation (ADPCM) SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_SignalLinear2ADPCM4Bits(mlib_u8 *adpcm, const mlib_s16 *pcm, void *state, mlib_s32 n); DESCRIPTION
The mlib_SignalLinear2ADPCM4Bits() 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.721 or G.726 32kbps 4-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. ATTRIBUTES
