It might just ditch it for all I know!

Theory agrees with measurement, great! ;-) But this is only the sanity check for the next one: 12 kHz square at 48 kHz sample rate. It should then look exactly like the 10 kHz square at 44 kHz sample rate! cheers, Nick. -- DeVerm ------------------------------------------------------------------------ DeVerm's Profile: http://forums.slimdevices.com/member.php?userid=18104 View this thread: http://forums.slimdevices.com/showthread.php?t=53345 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
