Time Stretch Multiple Tracks

[Rick Cornish]

Is there a way to time-stretch a soundbite that's been recorded on multiple tracks together?

I seem to only be able to a soundbite (manually, with the little hand) on one track at a time.

It was suggested that ‘scale time’ works, though I’ve not tried it. Trial and error on one until you get it where you want it, then, apply to the rest? So far I don’t see any scaling data generated from a manual drag, which is a….drag.

I’m not sure why MOTU never gave us the video series they promised us when ZTX was added. There’s this—and it may help—but it doesn’t cover nearly enough.

This is one of many reasons I use TwistedWave for such tasks. Although it also uses ZTX, many tasks are just easier. I posted a screenshot of the window last week. You can do each track separately or do a submit of the 4.

Come to think of it, if you do not have a MIDI track to sync to, David Das's video shows you how to create one in DP 11.2

The MOTU video in my last post should make it work.


Anyway, I would still use TwistedWave for this task. I see that he has a Windows version in Beta.

Here is the TwistedWave ZTX Change Pitch and Speed screen I posted earlier.

Time stretching via the hand tool should really be included as an option in Track Groups. Keep it simple for those not using strict tempo, tempo maps, MIDI, etc.

People seem to say "get outa here, go use Logic" for that approach.

Yup… that's *exactly* what I want to do.

I’m recording a solo jazz guitar album. Most tracks have no tempo. And there’s no MIDI in sight. Purely an audio recording project.

Thanks, Mike. The video was good, as far as it went. For what I’m doing, I’m not sure Twisted Wave would be the right tool, but I will download the demo tomorrow and check it out. Thanks, as always.

I'm going to regret sounding foolish for suggesting this if it doesn't work, but if all soundbites start at the same point, (or if you use the scissor tool to cut them all at the beginning of the section you want to stretch), is it possible to Command-Click multiple soundbites on different tracks and then use the hand tool to stretch them all at once?

30 day trial. When you the move the Speed slider (100% is zero), you'll see that the Resulting duration counter changes. You can do this in reverse by typing the exact time in seconds, then Tab out and notice the Speed change.

The David Das video shows how to create a MIDI track where none exists — new feature in DP 11.2. Then you can enter the sound bites per the MOTU video to match.

Fun?

Just a note...
I asked this same question a year ago.
I couldn't figure out how to add the link to it, so I just replied to the old thread.
It doesn't show up here, but maybe James could link it somehow.

I'd love it if MOTU could implement the hand tool for time stretching multiple selected soundbites.
Should be easy?

Hi Rick. You can easily do this with the Scale Time command in the Region menu. Just make sure Time Scale Audio is checked.

It deselects as soon as you try to drag, always has. If you try to manually drag multiples to the same exact sample end point through trial and error, you get brutally obvious unusable phase problems. It's a non-starter if the tracks are in any way acoustically related.

'scale time' - manual drag to determine desired change should generate scaling data that could then be used with 'scale time' - if it does, I can't find it. I don't think it's available.

I’d love to try some of this in a test project but I’m away for a week—I hope.

Stuck on a runway in San Francisco for 3 1/2?hours waiting for the wind to let our plane to take off. Hope we can make La Traviata at The Met tomorrow.
