recording vinyl for djing in live pitch down?

[wazun]

I just got an idea: Since when djing you are pitching your tracks up and down, wouldn't it be best to record your vinyl already pitched down, to have more (analog) information in the recording?
I don't really know how pitching digital audio works, but I can imagine that when you pitch a track up, your are taking several samples out of in a time slot and when pitching down, you have to create new samples to interpolate. Wouldn't it then be best to have that information already there?
If you are using an already pitched down track, then most of the time you would only pitch it up to beatmatch (sugin repitch algorithm) with other tracks?
What do you think?

try it and let us know.

interesting idea but most times you mess with the audio signal there will be a loss of quality. interpolation works best when you go up in exactly multiples of two, a multiple of say 1.2 wouldn't be as clean. that's my impression, I don't know exactly how Live is coded.

Hm, I just tried it but couldn't hear a difference. Seems the pitch algorithms are really good

very cool.

most times when I suggest people try what they're asking us to try they don't do it, props!

I never understand that, people ask "what happens if I push this button?" umm go push it and let us know.


thought of a drawback though... all your file sizes will increase.

yeah, the filesize is the major rub. i tried doing this for a while ripping my vinyl, but i couldn't appreciate any difference in audio... i find it's only worth it if you're playing midtempo (e.g. 33rpm when cut at 45)
