Pitch Shift Glitch

[ogbertsherbert]

I record dialogue for animated cartoons on Audition v. 13.0.9.41 and sometimes have to pitch shift the character's dialogue track down one or two semi-tones using the Pitch Shift Rack Effect. However, when I play it with the pitch shifter, it sounds like the vocals on the pitch shifted track are quickly wobbling between the left and right stereo channels. This happens in Audition and persists after exporting via a multitrack mixdown. What's strange is that if I play it over and over again, the "wobbling" quality doesn't always occur at the same moments in the clips. Does anyone know what is going on and how to export this audio without the glitchy quality? Thanks!

It's far from ideal to rely on a pitch-shift working fully correctly during a mixdown, when a lot of other stuff is happening. If you feel that you must have this in Multitrack rather than applying it to the original file, then the thing to do is to pre-render the track:

This will apply the process before the mixdown, and you will be absolutely sure that it's correct. Yes you can undo this and change it if you need to, but always put it back afterwards. This works on any track, and can in fact make many mixdowns a lot smoother.

Thanks for the response Steve! I tried pre-rendering, but the glitch persists after the mixdown. You mentioned applying the pitch shift to the original file -- could you briefly walk me through what you mean? Do you mean dropping the source file into a new multitrack session, pitch shifting it, and then exporting thatas my new source file for my more complicated multitrack session?

All you have to do is apply the pitch shift to the file in Waveform view and save it. If you subsequently import the file into Multitrack and don't do anything else to it, the pitch shift will remain as it is.

SteveG you truly are an AudioMaster! It worked! Thank you!!

Hello! I am having this happen to me as well, however I'm not sure how to fix it even after reading this thread. The problem is I'm only using the waveform editor and not even touching the multitrack editor. Any help would be greatly appreciated. This issue is variably persistent. Usually it's not happening, but currently it is and even restarting the computer fully doesn't solve the problem.

I'm not sure that this is the solution, but try shifting the channel from stereo to mono, then make you pitch changes. And when you're done you can save it back as a stereo file.

I've had a glitch pop up after pitch shifting some audio. It sounds like clipping, but it doesn't appear on the original file, which is nice and clear. 

I am a newbie with Audition, so many questions to resolve. Many thanks to anyone who can help resolve this, as the clipping spoils the mix..

Thanks

I had this Wierd wobbly audio problem too... like it was clipping or changing channels wierdly..

The Problem was generated due to the auto-fix feature here:
 
 
To fix: 
1) Uncheck the Use appropriate default settings in the pitch shifter. 
2) Set the Splicing Frequency to 5 Hz 
3) Overlapping to 50% 

Hope this solve this Issue.
