FS-8875 Enable faster beep detection Unnecessary computation of arc cosine is omitted and convergence is checked on partial results. Original frequency is easily retrieved when needed. 2016-03-27 20:39:53 +01:00			`#ifndef __AVMD_PSI_H__`

Added new FreeSWITCH module mod_avmd or the Advanced Voicemail Detection Module. It provides better detection than mod_vmd but is a little more CPU intensive than mod_vmd. Perhaps someone would like to CUDAfy this code? 2010-05-25 15:03:14 -04:00
