Huge fan of AudioShare
I mainly use AudioShare to hold audio that I export from other apps. I have the AudioShare icon on the launch bar at the bottom of my iPad Pro, right next to AudioBus. I also use it for importing tracks Ive recorded on the Mac, so I can mangle them with apps on the iPad. Basically, it is the centerpiece of audio production on my iPad, because every audio file ultimately either comes in by way of AudioShare, or recorded into AudioShare from another app, or exported from the iPad post-production. Very cool and useful app for audio production. The user interface is intuitive and laid out well.
