So I'm not sure what DSP processing you're referring to, but with squeezebox devices the files are sent intact unless you transcode them with some kind of filter (like Inguz or SoX) on the squeezebox server side. The Squeezebox itself doesn't really have a "DSP" (with the exception of the Boom). All it does is apply a simple linear volume adjustment to the bitstream. The math for this is not as complicated as a DSP filter. -- SuperQ ------------------------------------------------------------------------ SuperQ's Profile: http://forums.slimdevices.com/member.php?userid=2139 View this thread: http://forums.slimdevices.com/showthread.php?t=85691 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
