iOS Hook to app audio output

[dvdxyan]

is there a way to receive the audio output of an app vie another app (my app)?

say for example, an app that record the audio of the YouTube app and save it into a file.

oh and, of course, not using the mic....

i know that there is a way with inter-app audio but for apps that does not support inter-app audio is it possible? are there any low-level stuff that can be done?

thanks.

On stock OS iOS devices, nope.

The iOS security sandbox prevents snooping any audio of any other app unless it is explicitly exported by that app (inter-app audio, audiobus, etc.)
