Time-stretching audio too far

[Rmonik]

The weird swelling, swirling, wobbly noise that becomes apparent when you time-stretch an mp3 or wav just that little bit too far. I mean when you REALLY want to do a dubstep remix of something and you have to slow it down just that little bit too much. Its such a pain.

Evident in this awesome, but weirdly wobbly track:


(listen closely to guitar and vocals, not sure how well it comes out in youtube audio quality)

We need some better time stretching algorithms in the world.

Sounds like a bad stretching job. but it can be done... and if it can't you have to drive these effects so far it gets an artform itself

I agree that it can sound really obvious, but try different algorithms. Some of them work better than others for different uses. But it IS still a very artificial thing, you're actually adding/cutting waves in a waveform.

when its a guitar part I want to stretch, sometimes I get to the point where I just learn to play it and re-record it. Sadly, I don't have the ability to do the same for vocals.

there are a few different time stretching algorithms in FL studio, but all but 2 are pretty terrible past about 15 bpm. Dave recommended Paulstretch to me before, but I think that's more for 1000% slower type jobs

Don't forget that it depends a lot on the original quality too.

for some reason I find it quite hard to get accapellas in wav. I need to start sampling tracks from CDs instead of just using the 320 mp3 I have in itunes...

Laziness will be the death of my music *ahem* '"career" (read with air-quotes)

I use the "pro transient" mode a lot with time stretching. It works pretty well for most things.

I don't get why he didn't use a slightly higher bpm! That isn't much slower than the original. Also it does sounds like an awful algorithm was used, it skips slightly in parts. Watevs lol, Imma listen to some non-dubstepped Cranberries 'cause I'm Irish like that
