New on iOS17 we can control the amount of 'other audio' ducking through the AVAudioEngine. Is this also possible on AVAudioSession? In my app I don't voice input, but I do play voice audio while music from other apps plays in the background. Often the music either drowns to voice, if I use the .mixWithOthers category, or it's not loud enough if I use .duckOthers. It would be awesome to have the level of control that AVAudioEngine has.

I've been playing around with Montion Capture in ARKit 3. The motion capture requires an A12 chip or above. Can anyone tell me if the capturing works better on the A13 chipset versus A12? And by working better I don't mean just faster, but actually recognizing more movements/postures. If so I will go a get an iPhone 11.
