Lines Matching defs:an
35 * These routines comprise an implementation of the CCITT G.721 ADPCM coding
68 * term averages are computed and then compared to give an indication
110 * returns the integer product of the "floating point" an and srn
116 int an,
122 if (an == 0) {
126 } else if (an > 0) {
127 anexp = _fmultanexp[an] - 12;
128 anmant = ((anexp >= 0) ? an >> anexp : an << -anexp) & 07700;
143 anmag = (-an) & 0x1FFF;
459 * At the end of ADPCM decoding, it simulates an encoder which may be receiving
582 * The 4 lower significant bits of an individual byte in the output byte
