FLAC?

Lossless compression exists in many forms both inside and outside of sound files. A simple search on google should change your mind...

Plus, mp3 compression is designed to take out frequencies that are beyond what typical humans can hear, provided that the correct bit rate is chosen. Losing all frequencies above 18KHz? Well, when you can only hear to about 20KHz, that's not really that big of a difference.

Two things,

I think the mp3 -> wav what he meant by not losing quality is that the wav file will have the same frequencys as the original mp3, but yes if you were to go from wav -> mp3 -> wav then the final wav file would very likely lose some frequencys, provided it origionally had them.

And couldent you just put the cd in you computer and find out if you burnt the files as mp3 or if nero correctly converted them to wav by looking at the contents...?

I feel like supertreble and subbass, while not "heard" is still sensed by the body in a nightclub on a deeper level. "ghost in the machine" etc

Since most speakers and audio equipment will fuck with the signal anyways, however, you won't be affected as much by this unheard sound unless you're in the paradise garage or david mancuso's loft, ie somewhere with a great hi-fi system

As long as everything flows and it sounds good, imo, who cares what format is used.

Lol, right?! The most bizarre (and stupid) thread I've ever seen.

Or Stereo, Montreal... A system modelled after the Garage

Not true, maybe you are thinking of digitising and analogue recording of sound? The digitizing process takes a finite number of discrete samples of the continuous analogue wave (which essentially contains an infinte number of samples) so yes you will always lose sound. However it is possible to compress this digital representation of the sound without losing any information. Think about it, lossless compression must exist otherwise winzip, winrar etc wouldnt work.

False. Whether it is wav or Mp3, it is compressed. the frequency range stops at 18 KHz,for a 320 mp3 ; a 128 drops at 12 KHz.

OK, where did you get the idea that a 128 stops at 12KHz and a 320 18? The mp3 codec does not work like that. The mp3 codec compresses the audio by coding those parts of the sound that have the least amount of relevance to the way we hear it with fewer bits than the more significant parts. This basically means that the entire frequency spectrum still exists in the sound, its just that its coded in such a way that you cant hear it.

Sorry if thats a bit confusing, I'm not sure I've explained it that well. I wrote a whole research paper on this subject during my masters year at uni so I know a bit about it (if anyones foolish enough to want to read it drop me a pm!!)

Also, wav files are NOT compressed, they are simply a digital representation of the audio. Something that crossed my mind whilst reading this thread is that surely WAVs are a more accurate representation of what the producer heard in the studio (in fact, probably the exact file they redered from their sequencer) so, do we all cling top the idea that analogue is better simply because we are used to the sound coming from a peice of vinyl? Is it possible that in the near future we'll have a bunch of kids who never heard vinyl played in a club and are think that the sound quality is much worse because they havent grown up with all of their music being run through the analogue compression process of pressing to vinyl?

Actually thinking about it, its a moot point, give it 5 years and sombody will have created a "Make it sound like vinyl" VST plugin, nobody will be using mp3s and all our audio will be at 96KHz/24bit and itll all sound the same as before

EDIT: Dont get me wrong, I do still love my vinyl!!
