I couldn't resist, lets see how the Are 709 crowd feel about this endless futile debate.  =)

I am firmly against owning or playing out mp3's. On a big system, I have over and over again seen a dance floor go flat and gone up to ask the dj if the track was an mp3 and the answer is almost always yes.  So personally i don't need any more evidence. 

However, I have a few that are simply stunning tracks that I could not get in wav format no matter how hard I tried. But I make sure I have those clearly labeled in my collection, and when I play one out for the first time, if I see the crowd grow listless, it's out of my collection.

Ah the debate rages on... you just had to start this one!!

I've been playing a mix of 320 MP3s and WAV files for a long time now, on small and big systems, and to this day, no one knows the difference as to which is which; guessing wrong on which is which.

And there is evidence to support that the difference is inaudible. The science behind the MP3 proves that only small parts of the far low end, which you can't hear anyway, are actually removed. Further to that, presently now two audio engineers that I've been in touch with for the past while both say hands-down that the difference is absolutely negligable. Perhaps the difference is a bit more with psytrance where the lower end is more rounded and the frequencies are a bit different, but that's about it.

There is also of course the Fabric London test where djs and industry professionials were also fooled into which is which. Of course the argument can be made that djs have the worst hearing out of anyone; but I would have to disagree completely. Yes djs are exposed to loud music on a regular basis, but many are also the most careful with their best asset, their ears.  Apart from that djs, because their ears are trained better than the average listener, will be able to pick out things that others wouldn't.

So which begs the question; if djs, audio engineers and other industry people can't tell the difference, then is the regular person going to be able to? I think not.

I would love to take a pass through any of the big guys' music collection; with schedules they have, I'm pretty sure there's a wallet of MP3s on CD in their bags. I've read a few articles that attest to this fact.

That's my 2 cents...

I've been playing out on 320 kbps mp3's for a while.    I have no doubt that mp3's of a lower bitrate or ones encoded with a crappier encoding will sound totally flat, but I think there is definitely a point where it's not too bad, and 320's are beyond that.

 Of course there are so many factors, beyond just the mp3...i.e. the DA interface, the audio gear, the amplifiers, etc. etc.   

 Best to focus on playin' "sweet tunes"...

 what really grinds my gears is DJ's who don't pay for their mp3s.  I always have, but I've recently met a bunch who think that's silly, which I think is silly cuz it don't support the artists who make the good music.

Exactly!! Some tracks that come as WAVs sound worse than 320 MP3s. Completely depends on how they were produced...

And I'm a big supporter of properly paid for tracks, supporting the artists. Just because you can download them doesn't mean there was any less effort into making them.

Usually djs who rip off tracks from the web also play out low quality files. All wrong of course!

My 2 cents... sure, I might not be able to hear the difference between 320 and WAV (I don't claim to be an audiophile) but as a DJ, can I really say no one in the audience would mark the difference? Even subconsciously? If this were an economy of scarcity I might fudge around, but as is--there is so much great music out there that limiting myself to a strict regiment of WAV-quality music helps deal with the insane size of my collection. I can count on ONE hand the amount of times I have played an MP3 at a party in eight years (all were extreme circumstances where there was simply no other way to find the song)... plus (bonus round) dogs hear into the ultrasonic range culled by MP3 encoding, and every good festival has at least a few pups running around... wouldn't want to disappoint ;)

Haha... yes indeed pups a plenty. I never thought about the subconscious element of the music we play, which could be a larger part of the experience than we realize.

I too buy my tunes. Beatport I love you.

One place I've noticed where the difference becomes real obvious real quick?  Timestretching.  With Ableton Live it's quite obvious, and while I've not yet A/B'd it on my CDJ1000 yet, I've noticed tracks from MP3 start to have the kick and hh come unglued with much less of a stretch than a WAV file that's never gone through a lossy compression stage.

Hnmm.  Might try making a CD of WAV, 320kbit, and 128kbit mp3, then playing it at -6% with master tempo on, and seeing if there's an obvious difference.   I'll report back.
