Well, I think the CPU requirements depend on the size of the filter you want to convolve with. 45 second sweeps seem pretty standard - recorded at 16 bit and 44.1kHz that's a bit less than 10^8 data points. So if 10 operations are required per point you get something less than 10^9, so that would occupy a 1GHz CPU fully for one second. With inguz I get maybe 10% CPU activity for a few seconds at the start of each track, which fits roughly with the above - my server is dual core 2GHz or so. Brutefir is supposed to be very efficient, so my guess is 500MHz is more than enough, especially if your server is dedicated and you don't use sweeps longer than 45s. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=28368 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
