mlib_SignalLinear2ADPCM3BimediaLib)Library mlib_SignalLinear2ADPCM3Bits(3MLIB)NAMEmlib_SignalLinear2ADPCM3Bits - adaptive differential pulse code modula‐
tion (ADPCM)
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_SignalLinear2ADPCM3Bits(mlib_u8 *adpcm,
const mlib_s16 *pcm, void *state, mlib_s32 n);
DESCRIPTION
The mlib_SignalLinear2ADPCM3Bits() function performs adaptive differen‐
tial 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.723 or G.726 24kbps 3-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.
