More Timestretch Algos

Loving the Timestretch feature, would be great if the team could implement some more old school lofi option, a bit like Bitwig.



Rubberband has options that aren’t accessible right now

I would for example love being able to mess with formant correction…


i bloody love timestretch, the more native options the better for me.
something grainy for real time akaizms would be sweet (though offline akaizer or 0SXX do the job atm)

not sure how many parameters rubberband has but an option to adjust the amount of transient on Percussion mode would be so useful - something that leaves plenty of the attack of drums untouched but stretches out the tail.
at present it only leaves a sliver of transient intact and the result is too mushy / artifacty for punchy drums.

There’s some really great custom time stretch algorithms in MULAB, maybe the dev is willing to cooperate with the Renoise team if asked.

this thread reminded me of some of the streeeeeeetch functions in flstudio n i revisited last night. Edison has a killer ‘graincloud’ stretch to extend percussion tails AND a transient window parameter that sets how much attack to let through. sound wise its fantastic, really natural sounding. my only gripe is its not native in the Renoise sampler (ahem).

sounds similar to the mulab ones, also keeps the transients intact :slight_smile:

FL Studio Timestretch iss really insane - not sur what that algorthm is or if they made it by imageline but real real good resultzz with that one!!

Beyond new algos, I would like another timestretch mode. A mode where, when you change note, pitch is not affected but only duration. If for example the C-3 sample is 5 seconds, the C-4 would be 2.5 seconds, the C-2 would be 10 seconds, but with absolutely no changing on the original pitch. Perhaps there is already another way for doing this?


Not quite as convenient as the idea you described, and probably not suitable for all situations, but…

  • Take your sound and go into the waveform editor.
  • Create multiple overlapping slice markers at the same position within the sample.
  • Apply some unique properties (beatsync, pitch, whatever) to each individual slice.
  • Disable the [1>] toggle in the slice marker options so that the overlapping slices can play freely and won’t cut each other off.
