Do 320kbps mp3 files really sound better? Take the test! Do 320kbp, Maybe unscientific, but interesting results

128kbps vs 320kbps samples here:

http://www.noiseaddicts.com/2009/03/mp3-so...y-test-128-320/

EDIT: If you want to try the test yourself, DO NOT read on - there are spoilers further down this thread































































The reason I posted it (and the reason it's interesting IMO) is because most people got it "wrong".

43634 votes for 128kbps being better
vs
39578 votes for 320kbps being better

FWIW I thought both sounded like low quality vinyl (a bit muffled, a bit noisy), but the 128kbps version had extra artefacts.


Cheers,
David.

How will that lead to bias? Will people start picking the one that sounds worse because they assume that is the 320kbps?

Edit: The problem that I have with this test is that the file that "sounds worse" may, in fact, be closer to the original (which was not made available).
