Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

Changing Speed and Pitch of an Audio File Independently
Pitch-shifting in the early digital audio editors worked like an analog tape. Slowing down the playback rate lowered the pitch and speeding it up raised the pitch.
For many years now, a good number of editors can do these 2 processes independently. I am showing a few examples in this video using Lexis Audio Editor (Android, iOS, Windows) and Twisted Wave (iOS, Mac, online)
In those examples, I was looking for fun variations rather than fidelity or realism.
