Is there a supported way for apps on iOS to receive audio from other apps?

I make a Mac app where users can transcribe and translate audio from other apps. I want to bring this to iOS, and I'm wondering what APIs are available (if any) to do this. On MacOS I use ScreenCaptureKit currently, but that's not available on iOS.

Is there a supported way for apps on iOS to receive audio from other apps?
