Change Speed of Audio while Maintaining Pitch
I can’t believe this isn’t built it. When changing the speed of audio, how often do you NOT want the pitch maintained? You should have to take extra steps to make it chimpmunk, not the other way around. Its kind of essential for cutting in VO auditions ya know?. They aren’t read to time, so you have to squeeze or stretch just about every line, and obviously if voice quality is the very thing you are comparing you can’t be having every line of the script pitched differently. (Nor would such a cut be remotely watchable)
I’m amazed you have to go to Soundtrack for such a basic editing function. Isn’t there a way to do it in the timeline?
I can do it by ear with the AUPitch filter, but why isn’t there a checkbox for “adjust for speed change” or something. There must be a look up table out there somewhere that tells you:
If speed is 103% AUPitch filter should be 125.
If speed is 104% AUPitch filter should be 175.Can someone just tell me, in 5 steps or less, how to make a clip set to 105% sound normal?? Is it really as complicated as it seems? I’ve looked around on these forums but can’t get a direct answer.

Nope. FCP is a picture editor. The pitch shift function hasn’t been done yet. Avid didn’t have this for a while…now they do, yaaay! OH, wait, we’re talking about FCP here. Boooo!

Post that request…enough people ask, it might get addressed!

True, without Apple addressing this yet, it is still a manual effort (just like pumping gas.)
Check out this helpful chart I found by someone nice enough to take the time.
It got me in the ballpark for doing video speed vs. audio pitch adjustments. Once I was in the ballpark, it was minor adjustments after that:Hope this helps.

Doing a good quality speed/ pitch correction is not trivial. Most audio editing devices have licensed third party software like MPEX3 or Pitch ‘N Time.
However the license fee for this software is more than the upgrade price of FCS3 so don’t hold your breath for a picture editing system to include a high end audio plugin.
FCP doesn’t have a lot of basic audio editing functions like sample based editing and is not likely to. I can do basic picture editing on my Fairlight DAW but I don’t expect it to match FCP so why does everyone expect a low price video editor to be a high end audio device?
-
I don’t know what sample based editing is, but you can edit the audio on a smaller level than just the frame. I hardly have a need for it, but it’s always had it.
-
Avid has had this capability since 1997. At that point they had been around for 5 or 6 years and were on version 6 or 7. It’s about time FCP get this. I assume soundtrack can do it.
-
Sample based editing is the ability to edit on any sample and move clips in samples. FCP always cuts on the frame although you can move clips sub frame. Also sample based editors can do crossfades shorter than 1 frame which in PAL is 2000 samples @ 48khz.
SO what happens when the audio is exported via OMF? You know the AUpitch plugin is ignored by the OMF, so all the sound post people get are a whole lot of clips with the speed changes but not pitch corrected.

If you happen to know anyone with a ProTools system (the cheapest LE version has this option now), Elastic Audio is now a built-in feature (which i use to fit vo’s to ever commercial i make) which lets you shape the the audio to fit your needs.
there used to be a plug-in that comes as part of the DVToolkit for Protools, called Vocalign – which allowed you to set a source dialogue line, then a target dialogue, and it would reshape the timeline so that the second matched the first – perfect for replacing lipsynced dialogue. Although you had to be careful not to overdo the effect, it was pretty impressive
I would be surprised if you ever see that feature in FCP – its not really a video requirement, and it takes some extremely complex calculations to regenerate and repitch audio formants correctly.

You can do this in STP using the Time Stretch Process Option.

you rock. I knew this exact workaround had to be out there. It was in hopes of finding this table that I made this post.
Hey Creative Cow really works!

you’re right. Its usually a 3rd party plug in. I thought Soundtrack will do it for you though. And my point really was, if they give you they AUPItch filter, is it really that much more to have it automatically recognize what the correct pitch offset would be for the given playback speed? A guy posted a link to a (crude) table, couldn’t they just automate that part?
It seems like the hightech expensive part would the algorithms and software that shifts the pitch AT ALL. Once you’re there, its the easiest thing in the world to have it automatically know that if the clip is at 105% the filter setting is -60, if the clip is at 106%, its -72, 107% = -84 etc.
