Lines Matching defs:an
34 * These routines comprise an implementation of the CCITT G.723 ADPCM coding
74 * term averages are computed and then compared to give an indication
115 * returns the integer product of the "floating point" an and srn

459 * At the end of ADPCM decoding, it simulates an encoder which may be receiving
641 * The 3 lower significant bits of an individual byte in the output byte
