Right, so your statement "No DAC playing back 176.4kHz should touch the audible band " was meaningless to this test & only confuses matters. A minimum phase filter Let's see what Archimago did then - *"I took ~1 minute of these three 24/44 or 16/44 recordings and using SoX, upsampled them to 24/176.4 with either the linear or minimum phase upsampling algorithm, re-naming one file A and another B." * So he used an upsampling algorithm of either minimum or linear phase to bring these files to 24/176. Now tell me how pre-ringing at the Nyquist frequency of 88KHz is of interest to anyone & what this test is intended to do? ------------------------------------------------------------------------ jkeny's Profile: http://forums.slimdevices.com/member.php?userid=35192 View this thread: http://forums.slimdevices.com/showthread.php?t=103537 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
