Sort of. The definitions I've heard are that Oversampling is "synchronous" and Upsampling is "asynchronous". If you read the Resolution Audio whitepaper I posted earlier in this thread, it also seems to take on those definitions (that oversampling is based on integer multiples of the original sample, whereas upsampling does not). Upsampling can happen after the SPDIF interface, and oversampling happens in a digital filter prior to the DAC chip (my Dodson DAC does both upsampling and oversampling after receving the 44.1/24 signal...upsamples to 96khz, then oversamples 8x, for a final sample speed of 768khz, which is then fed into the DAC chip.) -- 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
