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.

Well, I picked the 320 Sample, but I was listening with headphones, and I've had a lot of experience being a critical listener to audio compressors. That being said, they're both probably pleasant enough to listen to for a typical pop/rock type of track on YouTube, etc.

However neither sounded top-notch, compression aside. It sounded like one big blur, either way. I think if it had been a more "crisp" recording, more people would have got it right.

Most of my listening / recording is with solo piano music, and I've become very good about telling what's going on with any recording I hear, from compression to type of piano, to microphone type and placement. With other types of music, I'm not as good.

This is the best comment of the bunch and really explains the results in a nutshell.

Let's see:

a) The recordings are both crap so does it really matter?

b) The 5-6 second distortion in the 128kbps sample threw me for a loop....without being familiar with the material at all I wasn't sure if the top one was missing it or it really was distortion? How do you know?

c) I need to hear the uncompressed version as a reference OR the whole thing is bogus to me...you must establish a reference in order to establish metrics, e.g. "Which one sounds more true to the original uncompressed version?" To my ears, thats the only issue that matters.

Finally, storage is cheap. Long live FLAC. :-)
