Hi,<br><br> I have only recently started using Asterisk and after doing a couple of stress tests I noticed choppy phone calls. Anyway, back in the days of 386 PCs I remember that using DMA to do memory transfers to and from the sound card was a big thing. Every game did it. This method reduced the CPU load which translated into higher frame count. I also know that nowadays Video Hardware has become quite powerfull. There are cards with 256 bit Buses and high speed memory in the ranges of 256MB and 512MB. I was wondering how hard would it be to code (either using OpenGL or directly using assembler) a routine to compress / decompress audio using the video hardware. Somehow placing the data in a 3d World Matrix and having all the data displaced or "translated" into a compressed / decompressed "frame" of audio, which could later be played back by to appropriate user (remote or local). If this could be done even the sloppiest video hardware could work as a powerful DSP.
<br><br> Or not just the Video hardware but also the Audio hardware. There are some pretty good audio cards out there that could do the work of expensive DSPs.<br><br>Any thoughts?<br><br><br>Thanks.<br>Haider Raza<br>
