Creating an audio 'scrub' type of effect??

[Broken Studio]

Hi,

I've been racking my brains on this one and cannot for the life of me come up with a solution. A band have requested a slow down, then speed up type of effect to cover a transition at the start of one of their songs, very similar to what the scrub tool sounds like when passing over audio slowly then speeding up again. I've heard this down on one or two songs before and it sounds immense but I have no clue as to how its done,

any ideas/advice would be greatly appreciated,

Cheers Paddy

I've done something similar before, in cubase. I basically used the pitch shifter on a section of audio and turned the time correction off, so when it lowered in pitch, it lowered the speed aswell. In the pitchshifter there a function where you can sethow much the pitch is shifted at the beginning and how much at the end, so it draws a kind of ramp. Basically in my case it gave the effect of something like a record suddenly being stopped.

I'm not sure exactly what you want to do, but I guess you could apply something like that to it somehow...maybe. And I'm not sure what software yor using and can't really tell you about how it works in others...but it might be worth looking into.

Perhaps if you could find a clip of what you are talking about someone could point you in the right direction...

Thank you, sounds exactly what I'm after although I would like my section of audio to sound like a record suddenly being stopped then started up again. I use Cubase, so will follow your instructions and hopefully mess around until I get it sorted,

cheers

Oh you could easily do that. You just need to do different things to different sections of the audio. If you have any probs with it just say and I'll try and put some screenies together

If you've got Pro Tools the Varify plug in will do exactly what you're asking for.

Just select the audio you want to affect, then click speed up or slow down, then click process.

Got it sorted, once again, thanks

Does anyone have a suggestion for this in Logic Pro? Unfortunately the Pitch Adjustment plugin changes the semitones in steps, so it's not a very smooth sounding change, nor does it slow things down. I couldn't find anything in the sample editor (nor would I expect it to have anything because it's a really bad sample editor!)

Can it not pitchshift in cents?

is it possible to take the track you want to scrub..

turn off its main output.

bus the track to a hardware output, and a headphone output(for monitoring)

run the hardware output into a free input, then set it as the input of a new track,,,,,record arm that track....


then you can monitor what you're doing on cans, and use the scrub tool that you mentioned to record a manipulated copy??

It can, but there's two sliders, one for cents and one for semi-tones. So I'd have to automate the cents down to -50, and then at the same exact time, automate cents back up to +50 and then decrease the semi-tone by 1. This is an absurd thing to do, and I'm not even sure it would flow properly.
