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:

"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.

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.
I emailed Rob Schryer who nicely responded obviously I'm not a huge computer guy and the MP3s are disguised as WAV files duh. Some slight differences on my crappy laptop speakers but uploading them to my NAS to listen on the big rig.
Close but the discussed mp3's are not quite as good on my system. I'm curious, what's your point of this comparison? 

Hello everyone! The results are out. The 24-bit was chosen correctly about 53% of the time, which means 47% of the answers were wrong. This is coin-toss territory. You can read the full summary here:
