Pro Tools 10.1.2 Elastic Audio Warble

[rogercollege]

Elastic Audio is acting strange. After changing the tempo of a track or group of tracks the audio has a warbled effect. I'm not doing anything different (that I know of); I'm converting each track from samples to click, then enabling polyphonic, then inputting different a tempo. The audio adjusts accordingly but the sound is not consistent...even when only changing the tempo by a few BPMs. This is particularly noticeable during whole notes or longer sustained notes. Ultimately, the audio is unusable.

I have used Elastic Audio extensively in the past, converting complex sessions, and have never had this issue until now.

I've been away from Pro Tools for a couple months and suddenly I have this new problem. I am I missing a step somewhere with Elastic Audio? Is anyone having similar issues?

10.1.2? I'm running 10.3.2 ...

What drew me to this post was "warble" cause I just used this when explaining the sound I got myself.

I recently have run into something similar, but I don't know if the circumstances are the same. I have an acoustic guitar track and a buncha vocal tracks and wanted to speed up the tune from 124bpm to 129bpm.

I accomplished this differently. I saw what measure the song ended at @124 and then changed the bpm to 129 and used the ALL group and used the TCE tool to pull all tracks to the left to make them faster.

Seems all are fine but the acoustic guitar has warbles in spots. I thought that possibly this was due to me not using more care in doing the tracks individually or making sure I was using polyphonic, etc.

I've yet to revisit that session to see if it's something like processing that track individually which will fix it? I figured I'd chime in so maybe others that are having or had this problem may mention it or have a possible solution.

First off, make sure you are always using Ticks (not samples). I always end off by switching to X-Form. Perfect every time.

Acoustic guitar is the problem. It is one of the audio sources that doesn't respond well to elastic audio. Some instruments fare better than others.

If you found a tempo that works for you, you can cut up the track and try different methods like the TCE tool after you slice the acoustic track in to a bunch of pieces.
That other thing is you can delete some of the warp markers if you want to keep using Elastic. You may find that trying to warp near the transitions is the better thing to do but may not change the speed enough for you.
Like Werner said, it's the hardest to deal with. Piano can suck too particularly in a ballad.

Thanks for the replies, I don't know if this was helpful to the OP, but I have asked if the part can be retracked at the faster tempo. If not then I can see about fudging around with it in the bad spots.

+1

Acoustic guitar drives the algorithms crazy.

+1 - X-Form takes much longer to process but is worth it for the quality.
