Your ears, you decide! ;) I personally prefer synchronous oversampling to integer multiples of the original sampling rate, rather than asynchronous upsampling, (which with my music library is mostly going to be at a sample rate of 44k1 or multiples), to the DAC max sample rate, which will typically be 192k or 384k, a 48k multiple. There is plenty of debate on this. One thing to keep in mind, there is a world of difference between up/oversampling in software and feeding it into a NOS DAC, where it isn't going to be processed with DF, or up/oversampled again on the chip..... Coming back full circle to where we started from, with the TI PCM5102 (and family), although there isn't a switch to disable the on-board DF/oversample, the higher the sample rate you feed it with, the less processing takes place. You send it data at 352k8 or 384k the "processing" is less intensive compared to feeding it at 44k1. eg. at 44k1 / 48k it applies an 8x interpolation filter. At 352k8 / 384k it applies 1x. ie. bypass. ------------------------------------------------------------------------ JackOfAll's Profile: http://forums.slimdevices.com/member.php?userid=3069 View this thread: http://forums.slimdevices.com/showthread.php?t=97803 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
