Does anyone have any recommendations for really good quality pitchshift and timestretch software? I run Logic and the in-house tools are very artefact-y.
Any help welcome!

if you’d go for a hardware solution i would point out the Deluge. Pitches/Timestretches down to 0.001 BPM. The result is still matter of taste despite quite remarkable, even be allowed to play that slow.
Apart from that there is open source, in example:
with algorithm “SuperVP” from IRCAM
or the “Rubber Band” Library
or the “Sound Touch” Library

Thanks for the replies, these seem great! Really appreciated!
I think these are all standalone applications, which is probably fine, would anyone have any recommendations for plugins which offer high quality pitchshift and timestretch too?
look for “paulstretch”. Which is an algorithm but also there are plugins that do super stretch with it, not sure if that sound coming of that algo is what you are looking for.

Thanks! I have used Paulstretch before, and it’s amazing for those ultra looong sounds…
I was thinking more along the lines of less extreme but high calibre pitch shifting ahd timestretching. But I will certainly check out this latest iteration of Paulstretch for sure
Reaper has both SoundTouch and Rubber band and other implementations readily available.
PaulStretch is a bit of stretch… It’s more a sound design tool for heavy changes of a sound (or gimmick in some people’s opinion)

Yes, agreed on that! And thankd for the recommendation… unfortunately i’m actually running Logic Pro rather than Reaper.
I already have some great recommendations here, but does anyone have any recommendations for Logic Pro compatible plugins which offer high fidelity ptich-shfiting and timestretching?
…how about paul stretch…?..a free plugin, mostly used for endless slomo stretch landscapes…but it worx also pretty nicely with short snippets and very minimal used paramters…while it always can stretch even milliseconds to eternal beauty…but defenitly one of the best stretch algos i’m aware of…especially if used not in realtime, since when it comes to realtime, even the most advanced stretch algos to be found in bitwig and ableton have their limits…

just asking out of curiosity, you have some public example maybe youtube in mind we could listen to?
I know only one device that can do extra ordinary stuff in the time domain and i had the pleasure of getting a whole day private introduction from Klaus Fischer in his studio talking about our strange futuristic ideas to start over his device. https://audios.klausfischer.de
If you read the history (might have to translate from german to english manually) the AUDIOS is a rare device (only around 50 ever existed). This information doesn’t help you much but high-fidelity timestretch and therefore also pitch is rare if ever achieved, certainly not in real time unless it is using hardware with secretive circuitry just like the AUDIOS.
Klaus’s Who is who (Referenzen) list is very interesting as well, cause almost everyone is one of the rare owners of this freak-in awesome device.
hear…

If you don’t mind “going back to the old school”, I had a lot of fun with this one:

Thanks for this! I think this is also stand alone (rather than being able to be used as a plug in in Logic). Looks interesting though!
Thanks! This thing looks insane!
When you say examples, do you mean examples of what I am trying to achieve?
If so, actually my needs aren’t that outlandish - Logic has a built in pitch shifter but I find it very artefact-y. For example, when you use it to pitch, say, a loop down it sounds almost like old school mp3’s , with lots of aliasing and artefacts.
So all I am really after is something that can do this at a high quality (similar for timestretching too).
Welcome! I read your post again - this time slower - it might be the complete opposite of what you are after, but my adhd still thinks it was worth sharing 
To be honest - apart from pitch&time plug by Rane I had in serato dj, I never used any other soft for this task - got Mpc 1000 and few other hardware samplers - apparently Rane did pitch&time as a plug-in as well and it was regarded very good quality - not sure if you can still get it but might be worth checking out

yep some example where you expect your definition of high-fidelity timestretch/pitch to be. 
Meanwhile, me going grocery store in the real time domain 
Yes absolutely! And tbh I’ll probably end up giving most of these open source ones a go at some point!

OK I’ll post a couple of things… but really stuff you can do with most samplers tbh

Ok, so the Rane algorithm is still here, but it’s not a cheap option:

Could also try traktor … maybe there’s a demo version
Import track / loop … define bpm ( if it doesn’t auto do it ) and pitch / key … press play and change bpm and pitch in real-time
Record the output
I often play tracks deliberately slow or fast and they still sound ok

Thanks for the replies! I’ll look into Serato, and I think I still have Traktor knocking about on my old computer, that’s a good shout!
