'Cannot use Voice Isolation with AVAudioRecorder or AudioUnit
I'm trying to record voice audio with either AVAudioRecorder or AUAudioUnit.
In both, after a recording has started, whenever calling AVCaptureDevice.showSystemUserInterface(.microphoneModes) and selecting voice isolation, I get the following error:
"Voice Isolation and Wide Spectrum are currently unavailable"
TLDR: What do I need to allow the user to change to voice isolation mode?
