Final Cut Pro Voice Isolation audio glitches in exported projects

Hello Apple Support Team,

I am writing to report an issue with the Voice Isolation feature in the latest version of Final Cut Pro.

When I export my project, the audio has glitches and random dropouts in parts where Voice Isolation is applied. Interestingly, these audio issues are not audible when playing back the project on the timeline; they only appear in the final exported file.

This problem started occurring immediately after the most recent update. Could you please let me know if this is a known issue and when we can expect a bug fix or an update to resolve it?

Thank you

This is a user forum, we are all users like yourself. You are not contacting Apple this way.


There have been a few posts about this problem, which appears to be a bug in the current version.

Some workarounds have been suggested - see this thread:



Final Cut Pro 12.4 audio dropouts when exporting with Voice Isolation




To report this problem to Apple - which you should do - use the feedback command inside Final Cut Pro itself:


I tested it on a 15 second and 50 second clip from a 1080p timeline and couldn't detect any audio problems in the exported video. (FCP 12.4)


Were my samples too short? Also they were single clips.


What are the specs of your video, audio and project?
