In a blind test, audiophiles couldn't tell the difference between audio signals sent through copper wire, a banana, or wet mud — 'The mud should sound perfectly awful, but it doesn't,' notes the experiment creator

Who knew listening to a banana sounded so good?

@BigJackBrass @marcoarment There was a classical music forum I was on years ago that did a similar experiment with various compression bitrates. Most everyone got the 64, but apart from that I was one of the very few to get four for four and it took some *work*.
@Dataless @marcoarment I've done a few tests comparing 128 up to lossless. Although I chose correctly, I can only claim to have been confident about the lowest quality; even then, I'm not convinced I would have been successful had the test not been a comparison. Taken in isolation these things can be extremely hard to identify.
