*Summary
Ability to add time stretch envelopes to items to allow smooth and gradual time adjustments to each item/take.
* Request
Take Time Stretch envelope. (AKA Take Speed Envelopes)
* Benefit
Sound designers regularly adjust pitch and time of assets.
Being able to use a take envelope to adjust an assets stretching would allow gradual changes to assets. Sounds like heartbeats, motors, stingers, and varispeed tape effects would all greatly benefit from having time stretch envelope.
* Reason
Currently, stretch markers are only instantaneous. A take speed envelope would allow smooth ramping of tempos giving control of the speed of assets. This allows more precise control over assets. Consider a heartbeat that speeds up and slows down. The pitch and time would each need their own envelope to give proper control of the sound as it changes.
Currently external tools like rx must be used for this.
* Implementation Suggestion
See attached photo. Having a take speed envelope (or time stretch envelope) in a similar implementation as pitch envelope would be elegant and in line with other envelopes.
True per-item tape scrub would be a fantastic feature for sound design in a DAW.
There is a nice tool called hourglass which automates source position which is another way of doing it.
Maybe have a source position envelope? That actually may be easier to use to picture. You know which frames need to be hit at certain points in the sound.
Would be nice to have that or at least varispeed with backwards in a DAW (scratching!).
EDIT: Yes I really think source position envelope would be way better in practice. You know which transients have to hit which specific time points in the video. That is actually way easier than trying to tweak speed until you hit the right position accidentally. How you best display what is going on is the question.

I have been wanting this feature since the stretch markers were introduced !
This would be absolutely amazing for sound designers.
Stretch Markers are very useful for tempo based work. But this doesn't really apply for sfx

+1 as well! For my work I automate item (spectral) pitch fairly often, but this can change the phase in a way that what you see on the waveform is not what you get. I would love to be able to automate item rate in a way that visibly effects item/waveform length; that would be a game changer for me!

Stretch markers are fiddly, unintuitive and too limited for sound design work. I use them because there is no better option. Would love to see something like this.
In Reaper you can play multiple project tabs at the same time.
Right click on project tab and enable these options:
'Run background projects'
'Run stopped background projects'
'Play stopped background projects with active tab'
'Synchronize play start times play background projects'
1. copy media item from project 1 to project tab 2
2. mute media item in project 1
3. automate master track playrate envelope in project tab 2
you can disable 'preserve pitch when changing rate' in media item properties (for tape style fx)
You can change resample algorithm in project tab 2 (project setings), good for sound design..
obviously you can automate things using custom actions/scripts. so you dont have copy items manualy etc..
check out these actions to manage multiple project tabs:
SWS: Open project list
SWS: Open projects from list
SWS: Save list of open projects
Bump! Having a time stretch envelope would be really amazing, and even more if when "preserve pitch when changing rate" is off, to act as a varispeed envelope, which would change both pitch and rate. Extremely useful for sound design!

I was just looking up how to do this in Reaper and came across this thread, so consider this a resounding bump and +1

Currently the best solution is a script by Buy One called “ Create pitch-rate (vari-speed) take envelope and render to new take”. With that it is relatively easy to draw rate envelopes.
Still a native implementation where the user can operate directly on the audio item would be great. And the envelope could be used not just for rate (when no algorithm is active) but also for each stretch/pitch algorithm’s special parameter (like window size or formant or whatever).
Stretch markers can have ramp for progressive change but I have to admit it is far less easy to use than envelopes points.
I was just trying to do this with Stretch Markers and it isn't actually TOO bad, and is maybe my fav solution to this so far... you just make stretch markers, move them, then use the command "Edit Stretch Marker at Cursor" to unlink the start and end rates. It's definitely much clunkier than just having it as an item envelope, but it's native and gets the job done, and doesn't require rendering new files

If you are fine with just linear rate changes where you can’t adjust curvature then that can be a solution for you.
