Pitch shift

[CHNL]

Hi,

For a comedy production I'm working on, the voice of a character (the baddie) needs to be altered. E.g. pitch shift. Is that someting that can be done with a mic cue by any chance? 

Regards

Hi there CH,

You can do pitch shift on a mic cue, although there’s a major caveat that currently the affects applied to mic cues are rather picky, since the mic cue just exposes all available input channels to the cue, and not all effects can handle arbitrary numbers of channels.

Mic Pool wrote up a great (extensive!) discussion of the state of effects here:

And Mic wrote about effects on mic cues here:

mic Mic mic? Mic.

Apple AU Pitch works with most interfaces, Ive got it running on an Octacapture

For interesting voice distortions give these fee plug ins  a try

Some of these e.g Spectral Harmoniser will just crash QLab as soon as you use them, but others work really well

Try Spectral Stretch, Spectral Pitch shift,

Here's a set up screenshot

Hello,

Thx for the feedback. Most helpful. 

Will a mic cue including pitch shifting require a lot of resources from my MBP? The current cue list includes a reasonable amount of sound fx and videos already.

No Pitch shifting doesn't use much resource.

As with all these things just experiment with it, and stress test it outside of a show situation.

If you want to use the effect  while playing a 16 track wav and 2 videos simultaneously then test it with 2 16track wavs and 3 videos. Then you can be reasonably confident you won't run int problems.

Hi,

Seems to be working like a charm, At the moment I only have  2in/2out interfaces available. Can I use two of those: 1 for all audio out and the second as input/output for the mic cue? Anything specific I need to take into account?

Yes you can

Only rule is that on a Mic cue Input and output have to be on the same device. (which is the only way you can set them up!)

hi Mic,

I indeed understood from the documentation on the website that I need to use the same device for in- and out-put for the MIC cue. Question is whether I need to worry about aggregating devices when using a second device for audio output. Read something about synchronizing word clocks or so. Or is that irrelevant in this case?

Apple has a very thorough, clear document about care and feeding of
aggregate audio devices which you can find here:

I may have misunderstood what you were wanting to do with your 2 2 channel interfaces, but if you want to use them independently, 1 for mic cues and 1 for playback, perhaps combining the outputs with a mixer, then as long as you are only using the analogue outputs of the 2 interfaces then you don't ned to worry about aggregates or word clocks

Thx Mic. That's indeed the set up I had in mind and I got it working yesterday evening.  Good to have it confirmed by a pro. Thx
