NAME

6       mlib_SignalLinear2ADPCM3Bits - adaptive differential pulse code modula‐
7       tion (ADPCM)

SYNOPSIS

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

DESCRIPTION

18       The mlib_SignalLinear2ADPCM3Bits() function performs adaptive differen‐
19       tial  pulse  code modulation (ADPCM) in compliance with the ITU (former
20       CCITT) G.721, G.723, and G.726 specifications. It  converts  data  from
21       16-bit linear PCM to G.723 or G.726 24kbps 3-bit ADPCM format.
22

PARAMETERS

24       The function takes the following arguments:
25
26       adpcm    ADPCM code array.
27
28
29       pcm      Linear PCM sample array.
30
31
32       state    Internal structure of the codec.
33
34
35       n        Number of samples in the source array.
36
37

RETURN VALUES

39       The  function  returns MLIB_SUCCESS if successful. Otherwise it returns
40       MLIB_FAILURE.
