Hi all,
I wanted to collect thoughts on the best solution for time-stretching. what are the best plugins / daw algorithms ?
avid sells X-FORM for $500 !!! ableton seems to be the best choice by many .
logic ... never convinced me .
whats best if you have to time stretch vocals - instrumental - whole tracks
and how about transposing ? pitch shifting ?
share your experiences, your conclusions and your choices.

 

zPlane Elastique is a great pitch/formant modulation tool, similar to Soundtoys Little Alterboy but cleaner, its good both for vocals and for instrumentals
ofcourse Melodyne is great too for transposing, mainly for vocals tho, i find it messes up the bass a bit when transposing extremely.

as for time streching im actually not too experienced with that, im using FL Studio so we have plenty of algorithms to choose from within the sampler so i know it wont translate to other DAW users, however from my understanding FL's time streching and pitch and based on zplane's algorithms

 

Zynaptiq TIME FACTORY II

 

PaulStretch is an oldie but it can stretch things ridiculously if that's what you want.

 

On a technical note, Elastique is like the standard algorithm for time-stretching and the author is Zplane. I'm talking only about the algorithm, of course the product zPlane Elastique uses it.

I think all DAWs (and many plugins) have a variant of this technique but there're a lot of versions. In Reaper for instance you can select several versions.
My point is that the most advanced version it's only used and patented by Zplane but that doesn't mean the others (I guess with patent expired or at least cheaper) used in other DAWs/plugins are not good enough.

I wouldn't be surprised if Melodyne have some of his incredible algorithms built on top of Elastique. They have the money the buy any license but that also means perhaps have resources to have developed one of their own.

And of course, how productive the implementation is matters a lot too.

 

Any tips regarding the best sounding timestretching algorithm for stretching complete (dance)tracks a couple of
bpm's lower or higher, preserving pitch ?
("best sounding = the least audible artifacts, the most preserving on kickdrum transients)

Live's Complex warp algo is for sure not one of them IMO.
Elastique Pro: also not really my cup of tea ..

 

still the ones from 2012-2018

 

WOW Thanx a LOT Lordsin That Plugin is amazin The ebility to stretch 800 + and more
Heard songs examples it is amazing I will USe it for soundesigning Thanx again

 

Zynaptiq TIME FACTORY II seems to be the best choice indeed, although I never used it, because .. I mean .. € 369 ..

iZotope RX 8 Time & Pitch with Radius algo still works for me.

I have to agree, although they did improve it lately (also with some kind of Melodyne emulation).

 

Reaper has plenty to choose from:

 

Paulstretch is in Audacity which is a nice way to use it. I use the Logic stretch and have no problems with it. But as mentioned, I typically do not do stretching over 5 or 10% change. Another thing, in breakbeat loops for example, I do not stretch the entire loop. I use Flex, and move the hits around so they fall on the correct beats. So any stretching is really just done to individual hits after they are correctly placed. The longer the audio sample, the more any flaw in the stretch algorithm is compounded; because it's calculating all the silence and all hits at one time. Across a single drum hit, it is barely noticeable.

Another good way to avoid Logic's time stretch is to take a breakbeat loop (as example), and drag it into a new Drum Machine Designer track. It automatically slices the audio and generates a midi track with the playback data. The loop can easily be retimed to a new bpm that way, just by simply editing the Midi data. (like how you would with a FL Slicer, for example).

You can get good results in Logic. If something is really prominent in the mix, giving it some more attention never hurts.

I usually do not use "music loop" samples directly, if avoidable. If you turn on Flex and change it to Flex Pitch, you can convert the loop to Midi data and then reassign it to a software synth or other sound source.

 

Pro Tools TCE: Pitch 'n time Pro

 

yes, but it's still 800$.

 

If it's just a couple of bpm's why not use repitch? That will have the least artifacts, and with that small a change the pitch will be almost identical.

 

This is like having deja vu about having deja vu

This post was in an earlier thread about the exact same question
https://audiosex.pro/threads/best-pitch-and-timestretch-algorithm.52142/#post-454931

and that post was itself referring to yet another thread that had already generated tons of answers
https://audiosex.pro/threads/how-to...e-preserving-quality.51128/page-2#post-439772

I doubt if anything significant has changed since both of the above threads

 

I am working with Logic and Bitwig for years and have worked a lot with Live up until a year ago -
and of these three DAWs the best time-strecth / pitch algos by very far has Bitwig (8 algos, including 4 by zPlane Elastique).
They are really really good.

The best algos for that in a a program for me has Ircam Lab's TS2. They are even better than Bitwig's and way way better than RX8 or Spectral Layers7.
Regularly TS2 is quite expansive ($ 199), but I bought it on the Intro prize, which was $ 49, and I saw it for this prize two or three times in the last six or so month.

 

Another great option is Serato Studio. The free version is limited but it does time stretching!

 

OK, Elastique algorithm is an other option, I believe most DAWs integrated it.

i like this application, simple and correct, I always compare it with Live stretching, the differences are there...
