I am trying to build a project that will allow me to use an iphone USB connected to a Mac as an audio output device. There are options to do this wirelessly like "AirFoil" but they all introduce latency during playback.
When connected via USB, the iphone will appear in Audio Midi Setup as a device. Currently it is only selectable as an input device. I believe it can be used as an external microphone or a midi input device. My hope is that through code, the grayed output selection could be overridden. Is this even possible?
From what I've read the AVAudioEngine might provide a solution to this? I have read through posts about listing all available AudioDevices by ID.
list-all-available-audio-devices
From here would I be able to set the audio output device as the iphone? Or is this something that would require a companion app running on the phone to route the audio as well? Any information would be helpful, thanks!
