Plug in to spped up audio

[kailpot]

Hi,

I'm looking for a plug in to speed up audio over a period of time (maybe called a varispeed?) I have 20 seconds of audio and want to speed it up from slow to fast linear over that period. Any suggestions,

thanks

unplug to slow down typing??

the trouble with these kinds of things is that w/o plug-sequencer integration that i am unaware of, you can't go faster than regular playback with a vst effect?? :p

the simplest workaround for this is to load your audio into a sampler plugin and use an envelope, lfo or other modulator (automation.. pitch wheel.. or mod wheel...) routed to pitch

The only way to do that reliably is off-line in an audio editor that lets you change playback speed with an envelope/drawn curve. You can do it in Sound Forge, I can only assume you can do it in Wavelab and Audition.

yes , audition will cover that , as well ...

...what about just changing/automating the pitch of the sample as you like? Wouldn't that work as well? ...if you didn't maintain pitch and tempo with regions, like you can in ACID?

I just tried it in FL and it's as clear cut as can be, if I understand you correctly. On the other hand, you haven't described how you want to speed it up. Would you like to maintain pitch as you increase/decrease the speed, for example ...or are you after an effect similar to slowing down and speeding up a record player?

dover666's ez-warp can be made to do this.
Though obviously you'd have to render it at 100% wet and also delete the silence at the beginning of the resulting new audio because, so far as I know, the VST standard does not allow for you to violate the rules of space/time and actually make audio happen faster than is playing.

Maybe you could override the internal soundcard settings and clock and the tempo and pitch would change accordingly? But rendering this would be useless, unless you recorded to tape or something.

Sounds like this is what you're looking for?

Wow, thanks for all your advice...lots to try out! Think the easiest solution is to export audio to a 2 track tape machine and use varispeed...only does +5/-5% so i might try some of these solutions and see what works best...thanks again for all your advice

This would probably be the simplest way, now that I think of it.

Try this:

- Load your 20 second sample into a sampler.
- Assign an envelope to the sample's linear playback rate.
- Set the envelope's attack to run the full length of the sample.
- Set the envelope depth to 200%.
- Play the sample one octave below its root key.

That'll give you a 2-octave playback sweep, so will go from 50% playback to 200%.

Really easy to do in a sampler like shortcircuit, which will look like this:



And will sound something like this on a 12-second clip:
