I don't think anyone is "jumping all over" him. I just doubt the methodology or the wording is completely unclear to me. And I just downloaded the .ZIP and brought up wave viewers on a few of the files. Zoomed in appropriately, the 'sinus 1kHz -90dB.wav' file makes, as expected, a sine wave, though I can see steps in it, that is expected at this low level. Values range from 265 to -266. The interesting part is that 'sinus 1kHz -90dB.wav.lame.mp3.mad24.wav' looks -exactly- the same. There is not a single artifact of compression that I see. the only obvious difference is the range is slightly different: from 268 to -269. And even more interesting: 'sinus 1kHz -90dB.wav.lame.mp3.lame16.wav' looks like poop. It is far closer to a square wave than a sine wave, and even has very sharp corners. The range of values are entirely different as well. It is 0, 1 and -1. the 'sinus 1kHz -90dB.wav.lame.mp3.mad16.wav' is also very different from the source. The values range from +4 to -4 , and the waveform looks only barely like a sine wave, but I see values bounce like: 0, -1, -1, -1, 0, -2, 0, -1... I am at work: no headphones here, and my PC speakers suck so it's not like I could hear anything anyway. (Not bad for background music, but not about to pick up subtleties...) But from looking at the waveforms in those files, yeah, I am sure two of them sound the same, one is almost silence and one is... I have no idea what.
