Incompatible plugin(s) found! help

[marcbacher]

I was upgrading to 3.3 and upon install this message popped up. I’m not sure what it means and how to fix. Any help will be greatly appreciated.

appl/aufx/vois/Apple: AUSoundIsolation

I am on a new iMac with M1 chip

this message popped up.

So you can ignore the error. When Audacity first starts up, it catalogs all of the available sound processing plugins on your machine. This message simply informs you that you have a plugin by that name but it won’t work with Audacity for some reason. It doesn’t affect anything else.

Ok perfect. Thank you for helping because I was lost. As a lament, can you explain what the plugin is used for and why Mac wouldn’t have it? Is it a common plugin that I need to get?

I found this:

Vocal Isolation?

Beginning in iOS 16.0 and macOS 13.0, a new audio unit entitled AUSoundIsolation silently appeared. As of writing:

• If you search the unit’s name’s on GitHub, there are 9 results.
• If you search this on Google/Bing/[…], the majority of results are Audacity users complaining about it being incompatible.

(…in other words, another typical unannounced and undocumented addition. Thanks, Apple!)

This unit is silently the backbone of Apple Music Sing. A custom neural network is applied to the isolation audio unit, separating and reducing vocals. This is done entirely on-device, hence Apple’s mention of:

Apple Music Sing is available on iPhone 11 and later and iPhone SE (3rd generation) using iOS 16.2 or later.

This aligns with their second-generation neural engine (present in A13 and above).
