Best Speed / Pitch Correction method

R

RadioMan203

I'm trying to duplicate some edits of music originally issued on 45 rpm singles. On a couple of tracks the actual single was pitched up anywhere from 3% to 5% when the record was played on speed (confirmed on a Technics SL1200 MKII using an original issue single).

The problem is trying to perform this pitch/speed correction in the digital domain. When trying to do this in Adobe Audition 1.5 the stereo image starts to get unstable and a noticable floating effect between channels can be heard. I tried a few other programs on both Windows and Macintosh platforms and this effect goes from quite noticable to making the audio most unlistenable.

Is there any alternative other than spooling the audio out via analog to my Otari reel and then playing it back into the audio computer at the desired pitch? So far I have yet to discover a way or a program that will allow me to do it digitally without all the artifacts.

Hi Mike,

Thanks for the tip. Unfortunately I don't have Protools (yet) so that limits my ability to try their demo. Hopefully I'll either find something to tide me over or I'll have to make the jump.

I've found that the best way to go about pitch and speed corrections in Audition is to do the two steps separately. When I pitch something up but want to keep it in the same key, I'll use the resample option, get the tempo where I want it, then use the pitch option to bring the key back down. It's not perfect, but it's better than what the built-in tempo option will give you. As someone mentioned here before, though, the pitch effect in Sony's Sound Forge is a heckuva lot better hands down.<P ID="signature">______________

Another good plugin is a DirectX plug from Delay Dots called PitchWorx DX. The best part....it's absolutely free. I think it's as good as the Sonic Foundry (Sony) pitch/tempo shifter. Maybe better.

In discussing this with a fellow production rat he pointed to the solution that was right in front of my face! I burned the correctly edited (but slow) wav file to a CD. I then took the CD and played it from a variable speed CD player pitched to the correct speed. I took the digital output from the CD player and fed it back into the audio workstation. The track was pitched correctly and speed corrrected with zero digital artifacts introduced.

Hope this comes in handy for someone else.
