Running T-Test and Analysis of Variance (it's in the spreadsheet) on the non-insane results, I can confirm that the 128kbps CBR sample is lower quality with an extremely high degree of statistical confidence. Beyond that, as you'd expect, nobody can hear the difference between a 320kbps CBR audio file and the CD. And the 192kbps VBR results have a barely statistically significant difference versus the raw CD audio at the 95% confidence level. I'm talking absolutely wafer thin here.


Seems pretty well-done. Thanks to Zao for the link.

I wouldn't necessarily have such an expectation considering there are members here who can (or at least claim to be able to) regularly ABX 320 CBR against lossless on normal music samples.
