Can you distinguish mp3 from wav?

Check this site : http://www.npr.org/sections/therecord/2015/06/02/411473508/how-well-can-you-hear-audio-quality

I made this test on my crappy laptop speakers (integrated) and I got 5 of 6 correct, I messed up Mozart - I did label the 320kbps mp3 as lossless

Cool study, but you should try it with proper/real speakers.

I plan to do it when I come home but on quality speakers the differences should be even more notable - at least I think :)
The think is that mp3 is deforming sounds like human voice and drums in a certain way and if you know what you should search for it's quite easy

No, I can't. 2/6 correct. Used headphones plugged into the PC. Don't have an amp or anything like that, so maybe that's why. But then again, I probably have shit ears.

3/6 on crappy earphones plugged into my laptop. I got 1, 3 and 4 wrong.

I think anyone who pays extra for Jay Zeez 'high def' service are doing it purely for the snob value....

Now that Chief Mouse said he got 2/6, I dare to confess that I also had the same score. However I got Mozart right !

I think it is due to listening too much to the Queen music on my phone which is MP3 :-)

4/6 ... played with external speakers plugged into computer
I got Jay Z and Kate Perry wrong :)

You got 3 out of 6 correct!
Despite its bad rap, the MP3 is actually a remarkable feat of engineering, and pretty good at filtering out mostly the sounds you can’t hear. Depending on the quality of your headphones, you might be able to distinguish between the two MP3s, but you’re unlikely to do better without an amplifier or a digital audio converter.

I used generic headphones (not earbuds) plugged into a PC

Fuck me :-\

I got 5/6,
from my cheap laptop speaker.
I messed up Kate Perry, thought the 320kbps as the lossless.
But please, don't make me listen to Kate Perry again.

@ Beta: are you, by any chance, still using Internet Explorer 7? (:-<)

Either you're really lucky or, I don't even know. I didn't hear much difference on headphones not to mention a bloody laptop speaker! :-P

Online quizz always tell the truth :D
Or, I can be randomly lucky sometimes.
But I did listen to the samples twice. Not that easy to decide after the first time.

The Kate Perry samples, I listened to it thrice but they all sounded bleh to me, hence the wrong decision. Not intentionally bashing her, of course.

Ditto BETA215's situation. I could've guessed by the lag time of the samples on my phone but until I get to a pc I'm not gonna participate

As a live sound engineer for many years I'm guessing I'd get at least 4/6. At least.

There are washy textures that come out in mp3 as well as decay differences and sibilance. Just alerted dynamics. At least they give you choices instead of "mp3 or wav"

That's very cool. I'm going to forward it to friends
