Timestretching Tools

So I've been scratching my head as to how I should go about changing the pitch/timing of samples. I'm mostly interested in changing acapellas so you can't really tell where the original came from. I've seen lots of threads about pitching samples up with lots of reverb to get Burial style vocals, but I'm more interested in pitching on the fly instead of just changing the pitch of the entire sample, if that makes any sense.

Jamie Vex'd seems to do this quite flawlessly, for example in this:



So far I've tried pitching/changing the speed of samples in audacity, but I haven't had any luck, I'll always get a click at the beginning of the pitched part, and it just sounds too quantized. Maybe that is the answer and I'm just not good enough to make it sound good :dunce

Anyways, are there any tools that allow pitchbending/timestretching in a portamento fashion, so that the bending doesn't sound completely off. For example, say you want to pitch something from a E to a high D is there a tool that will add some portamento or glide between those, just a milliseconds worth so it feels smoother? Or is that even possible?

you could automate the pitch?

Hmm yeah I think that'd be the best bet, I'll try putting some clips into a sampler to see if I can get the right sound.

or create a automation clip for the vocal over the track as its playing where ever you want it to change pitch then obviously edit it up or donw?

oh and make them gradual curves to make it flow better

If you're using Ableton its sampler has a portamento/glide feature

instead of having to automate the pitch of a sample, use pitch modulation

Basically, hit up Melodyne or AutoTune and get on that shit.
I dunno if you can control them live, but I'm sure its feasible.
