I have one iOS app that is an iPad touchscreen virtual musical instrument. I have another app that is an audio visualizer (36-th octave spectrum analyzer). I used to use inter-app audio to pipe audio samples from the first app to either the second app, or to GarageBand for recording. But inter-app audio has been deprecated.
My question is what is Apple's suggested method (API's etc.) to get audio samples generated in one UI app to play and display in another UI app (say on an iPad, where both apps can be on the display) in performance-near-real-time without using inter-app audio?
