I just upgraded to a Mac Studio. I'm using a Scarlett Solo with external speakers for audio. When using Final Cut Pro's Voice Isolation feature, my audio is distorted. No other plugins cause this. When I switch to the Mac Studio speakers or Mac Display speakers, there is no issue either. Anyone else have this issue or have a fix? Thanks.
Mac Studio
All,
Good news. I just figured it out. I went into the Focusrite Control app and tried selecting a different sample rate than the default. It was set to 192kHz. I switched it to 48kHz. No more stuttering/drifting issues. Thank you all for your suggestions!

I just had this same issue. This is something Apple needs to see and test. I created a file after applying Voice Isolation. When I play the file back on the built in speakers of a MacBook Pro or an iMac it plays fine in terms of the audio sounding correct. When I hook the headphone jack of both a MacBook Pro and iMac to play on external monitors the file audio is distorted. I tested this on 2 different models of MacBook Pro and one model of iMac. Very frustrating as this was for a major presentation. Apple please advise.
Hi all,
Thanks for the follow up questions.
Voice Isolation works just fine via:
-Mac Studio speaker
-Mac Studio Display speakers
-Headphones plugged into Mac Studio
Voice Isolation plays back distorted via Scarlett Solo (Connected via USB C to USB A)
Exported file's audio plays just fine.
Here is a link to two files for comparison:

That is odd. Have you contacted Focusrite support to see what they say? The latest driver I see listed on their support page is 3.10.0 but I don't see a date. What version are you running?
In the Mac playback video, the audio appears to drift considerably in the short clip. I wonder if the real-time voice isolation processing causes the sample rate to drift. What happens if you render the clip?
In an exported video. I can upload a file tomorrow as this is a project for my educational institution that I was working on. I will do a bit more testing as well and provide further info about machines, etc.
Thanks.
The slider control doesn’t mitigate this at all?
No. Once I switch over to Studio or Display speakers, the distortion is gone. Weird dynamic.
Are you hearing this when playing back in FCP, or in an exported video?
Is this only with external monitors or with headphones as well? Would it be possible to upload an original file that shows this behavior to test it, perhaps to WeTransfer or Dropbox or similar?
