centripetal acceleration:
ac=v^2/r
Acceleration equals velocity (speed the turntable is spinning ) squared, divided by the radius. the radius has to be figured by where the needle is sitting on the record. Outside/beginning of the record = 6inches. The closer you get to the center, the smaller the radius becomes. When you divide the velocity by the smaller radius this increases the acceleration. Once again, the changes are slight, but as the math is telling me, it's there.
I could be dead wrong here, but using physics, it makes perfect sense.
Sorry to take the thread off on a tangent.
i got a an E in a level physics, so equations like that are a bit hazy in my mind, but as parson says, it would be cancelled out by the fact that the same thing happens during the cutting....
Beat me to it, but this is the answer. There is a slight acceleration, but since the same thing happens in the cutting process it it canceled out. In fact the first version of the Serato Control Vinyls forgot to take this into account mp3s were speeding up twards the end of the vinyl, which they called "Pitch Drift", they had to come out with a second version of the plate that took it into account.
And I have to agree with Parson on the CDJs although for a different reason. I dont look at the BPM counter either, since when I started there werent any and it didnt matter to me, so I touch the platter alot on my Techs. The problem I have with the Pio CDJs anyway is that the platter doesnt move, so when I go to adjust just a little bit as if I were dragging a finger on the side of the platter, I sometimes throw the whole thing out of whack. Thats why I prefer Serato.
Best Technical DJ..? From what Ive heard of dubstep djs, N-type and Plastician... locally, Unit, KnifeDreams, actually most dubstep djs from LA hold it down... other styles - DJ Rectangle and Z-Trip, Frankie Bones, Hawtin, Doc Martin, MarkEG, Mark N, Jazzy Jeff... I could go on for ever
