My understanding of the benefit of oversampling/upsampling is primarily to get the digital artifacts resulting from imprecisions in the DAC process to a higher frequency so that they can be more easily filtered in a frequency range that won't impact the audible range. -- PhilNYC Sonic Spirits Inc. http://www.sonicspirits.com ------------------------------------------------------------------------ PhilNYC's Profile: http://forums.slimdevices.com/member.php?userid=837 View this thread: http://forums.slimdevices.com/showthread.php?t=26685 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
