Blind Test: mp3 vs. 24bit


Hello Audiogon Members~
PMA magazine is conducting a study to see if we can hear which is better between an mp3 and a 24/96 file in a side-by-side comparison. So far, the results are surprising. If we all participate, we’ll know the truth. It’s also a fun test. Please go to the page below to participate:

Ok, done the test on headphones and in all 3 cases (Black Sabbath, Patricia Barber, Anne Akiko Meyer/Vivaldi) I marginally preferred sample a over sample b.

Let's hope the findings are better than a 50/50 or 60/40 result.
Way better.
"So far, the results are surprising"

I’m not surprised.

Although many people apparently find 128kps indistinguishable from CD, for me once I get past 192kbps it becomes extremely difficult to tell any difference.

Not to say it also defeats the purpose of
enjoying the music.

Listening to music should never be about straining to hear minute differences, should it?

It’s quite a large file (190mb), so I might have a go later on my PC.

Wow, that’s close.

When you consider the fact that the MP3 versions were between 220~260kbps, and not the highest available, 320kbps, then you can see the disparagement of MP3 for what it’s worth.

As I said 12 months ago, it would appear that once you get above 192kbps it becomes very difficult to distinguish MP3 from anything higher.

Even all the way up to 24/96!
