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.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
PaulXStretch - Extreme Time Stretching
As discussed in another thread, I've taken over maintenance of the PaulXStretch application/plugin and have made some updates to the Mac/Windows version, as well as getting an iOS version working (standalone and AUv3 effect plugin).
PaulXStretch is designed for radical transformation of sounds. It is not suitable for subtle time or pitch correction. Ambient music and sound design are probably the most suitable use cases. It can turn any audio into hours or days of ambient soundscape, in an amazingly smooth and beautiful way. The project is open source and free.
The iOS version is now in public TestFlight, so hopefully I can get a few more people to give some testing feedback.
I also made a new website for it, which has links for all the current builds, and also to the iOS TestFlight public signup.
Please let me know if you have any questions... and also try out the desktop versions as well!
