Time-stretch Vst Plugin

I’m looking for a GOOD time-stretch plugin, but cannot find one. The only plugins I found can do something with pitch shifting, but not realtime time-stretch.

You do realize the, somewhat, difficulties involved in a time-stretching vst-plugin - the audio input is time-constant, but you want the output to be shorter (impossible without prebuffering, as it would catch up with itself timewise) or longer (possible).

It is of course solvable in different ways. You could do it with VST Instruments by sampling what you want to timestretch and then control the timestretching live in Kontakt (which has nice ‘online’ timestretch imho). You could also timestretch your samples offline, for example using Dirac (which has been posted here on the forum earlier).

Not sure if this answers your question. ;)

Thanks for the info guys!

yes, realtime is pain.

Kontakt 2 time strech/pitch shift is very good. Its not realtime but works just fine. You load your samples up, choose “time machine 2” as a source and make adjustmens to parameters. you can get very clean sound it you choose them right.

I use Audition for offline time-stretching. This will do the job also.

yes, but Kontakt 2 IS kinda “online” :) if you know what i mean. You load your samples into vst sampler and you can tweak them as you want and listen to it right there in your sequencer. no need for offline processing. its just that you cant use “direct from disc” in that way. As you tweak something (time strech parameter) Kontakt processes your sample right away and store the result in ram.

Celymony Melodyne or STFU :P

imo it sounds even nicer if you use E1 (pan-coloumn)

c-4 … E1 0900
c-4 … E1 0900
c-4 … E1 0901
c-4 … E1 0901
c-4 … E1 0901
c-4 … E1 0902

and its getting crazier when adding 0B00

c-4 … E1 0900 0B00
c-4 … E1 0900 0B00
c-4 … E1 0901 0B00
c-4 … E1 0901 0B00
c-4 … E1 0901 0B00
c-4 … E1 0902 0B00

check it yourself
( btw, try 0E01 instead of 0B00 / B0 instead of E1, it sounds a bit different )

nice trick, guest.

I hadn’t thought of that!

prosoniq timefactory is definately the best. I need pitchshifting quite often, when doing remixes I often change the original tempo of the track and also I use pitchshifting for fake (chord-)progressions.
I tried around with quite a few plugs/programs and timefactory stands far out from the rest.

Especially if you have the solo-tracks you can go very far down and up (in terms of bpm and halfnotes), I like the BPM mode where you can input the original and the desired BPM of a track (that thing is rock solid) and it just sounds like the original if you keep within the +/- 33% percent boundaries and it even does a good job on full songs. nuff said.

I theenk also dbglitch has a time strech feature built into it, doesn’t it?


Yep. Admittedly it’s quite a simple stretching method that I made, basically just cross-fading between grains, but it can be nice if you want that classic junglist sound, haha. Here are a couple of audio demos:


Due to the way that Glitch works you may or may not find it useful as a standalone time stretching effect though. If you set the first sequencer step to the stretcher effect then erase all the remaining steps, the stretcher will play for the entire duration of the sequencer (64 steps by default) but the effect will reset when the sequencer wraps back around to step 1. In other words the stretching does not continue to play indefinitely, it only works practically within a certain range, but it can still be useful in the right situations.

you should check tutorial songs that come with renoise ;)

9xx alone with a single note seems better sounding than continuous notes with 9xx + e1/b00 or b0/e01. Using a single note with the latter combinations gave a lot of clicks, but still, using continuous with them sounds (to my ears) a bit more glitchy than just 9xx alone. The retrig doesn’t seem to do much of anything, at least at high speed/BPM.

Pitch shifting and time stretching is basically two sides of the same thing. For example, play a sample, an octave lower than it’s sample rate, and shift it one octave higher with a pitch shifter effect, and you’ll basically have half speed time stretching.
