*** But a more interesting shock is to learn that some, often cheap, implementations are near-perfect. ***Are you talking about Secret Rabbit Code? I must admit, it performs better than I expected, but I wouldn't consider it "near perfect".
The "winner" in the comparison appears to be izotope 64-bit SRC. Not surprisingly, since the comparisons were done with the input of Alexey Lukin, who is associated with izotope. Still it does demonstrate the advantage of 64-bit precision.
Audition and BIAS Peak fares well, but then I expected they would.
*** You have to be thorough, that's all. Apparently that was not the case with the designers of a lot of the pro tools. ***
I think there's a bit more to it than mere carelessness. Most implementations have to trade accuracy with speed, and many of the tools were originally written when computing power was a lot less than today, and the algorithms haven't caught up with processing power.
Which brings us to the original topic of hardware based resamplers, implemented on a chip, which is typically what is units like the Lavry and the Benchmark DAC.
I would like to see how a hardware SRC performs on the same tests - I suspect the results won't look good (the precision on a hardware SRC may potentially be as low as 24-bit fixed).
