i think spin realizes that and MP3 isn't a master...but he just wants to hear the sound differences between people's stuff and his own.
anyway though - everyone could send him like a 10 sec. .wav clip or something, that would be decent enough i'd say...
but yeah - i just got a brickwall limiting set at (i think it was -.1..but coulda been 0)....and its basically hitting that non-stop (so over here it's not actually CLIPPING, but indivually the tracks are...)..
i made a master of it anyway though, just basically to put a low end in it, and take out some of the harsh highs that hurt me...haha so nothing great, but just to see how i would have loved to hear it RECORDED in the first place at least, i think spin is posting it up on that webpage...
