Numerical calculation errors are easily demonstrated as measurable in the real world e.g. DAC on-board digital filters, SRC software. It's an absolute myth that these calculations are generally perfect in the real world (even though they could be, and in particular cases are perfect).
For reference:- (1) Benchmark are one of the "good guys" and yet: https://benchmarkmedia.com/blogs/application_notes/40489089-benchmark-dac2-vs-dac1-side-by-side-measurements "A careful examination of the two curves will also show that the DAC1 has slightly more ripple in the frequency response. However this ripple is insignificant from an audibility standpoint and it is hard to see even on this expanded scale. This difference is due to the improved digital filters in the DAC2." Note the DAC2 still exhibits this, albeit less. (2) Comparison of various popular SRC software, some quite poor!: http://src.infinitewave.ca/ Also there are historical shenanigans with cheap and/or poor ADCs which have caused measurable issues in a great many recordings. So I think the argument descends to audibility, it can't realistically be won at the level of digital theoretical perfection. Please understand my point: I've no evidence that the above issues are audible. Check it, add to it! http://www.dr.loudness-war.info/ SB Touch ------------------------------------------------------------------------ darrenyeats's Profile: http://forums.slimdevices.com/member.php?userid=10799 View this thread: http://forums.slimdevices.com/showthread.php?t=106935 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
