    AMDFan: Igen, úgy van, tehát mindegyik tesztfájl 24/96-os:

    "The sample was taken from Chuck Mangione - The Feeling's Back, unaltered 24/96 LPCM.

    1. original, unaltered sample.

    2. fake 96 kHz. The file was filtered exactly like resampling to 44.1 kHz would, removing everything above 22.05 kHz. To make the file indistinguishable from the third, I had to add some high-frequency content. I chose completely random (white) noise, shaped to match the waveform.

    3. CD quality, the "worst" in the set, because additionally to the processing done to the fake 96kHz the bit depth was changed to 16 bits. 1 bit TPDF dither was used, no noise shaping (so no one can complain about moving the noise beyond 22.05 kHz).
