Hello,
I can record with voice isolated when I run the "using_voice_processing" sample project (link below) on either iPhone 12PRO (iOS 15.6) or iPhone 11 (iOS 16.0.2). Running it on iPhone 14PRO and 14PRO Max does not isolate the voice. I have confirmed voice isolation work with FaceTime on the iPhone 14 but it does not filter out background music when running the sample application.
