You can definetly hear it is pitched up.

  That's so interesting. I was thinking about comparing the length of tracks with the CD. Or using OpenCV to count the RPM. I had no idea people could hear subtle pitch changes like that.

    It's almost a semitone off, which means one key on a piano keyboard. People do hear that.

    It's more obvious on the second clip to me but both sound clearly off to my ear.

      Vocal made it more immediately obvious, but both was fairly noticeable to me (though I'm not sure how much I would have noticed the first one if it wasn't such a well known piece).

    Oh, one can clearly hear that is off-pitch. It's not some skill or talent that people are born though, it definitely can be trained. I was going to recommend you to look into the Philips Golden Ears Challenge, but it seems that they shamefully took it down. It was this website that went at lengths to show you different aspects of sound reproduction and you could make a ton of different A/B tests for things like coloring, compression artifacts, sound stage and tonality. When I finished it, I worried for a while this was going to ruin music for me and that I would become some kind of audiophile snob. Turns out the opposite happened. The ear training was very helpful to learn to separate the "good enough" from the "great" and the "great" from the "good-but-overpriced-audiophile-bait". I could get the $1000+ gear from a colleague who loved to spend money on audio stuff, give him an honest assessment about it and still go back contently to my $70 headphones, playing on my DIY amp and sourced from a $5 USB board...
