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.

Important Announcement about Auria LE

We noticed this morning that Auria LE has appeared on the App Store, apparently with Audiobus compatibility.

We strongly recommend that Auria LE only be used with Audiobus on the iPad 3 or 4.

Unfortunately, Auria LE has not yet been registered with our database, which means until WaveMachine Labs do so, Auria LE won’t be able to be used with Audiobus.

Here’s a workaround for that:

  1. Close all audio apps (see
  2. Launch the Audiobus app
  3. Launch Auria LE
  4. Switch back to Audiobus, then you will see Auria LE in the list.

IMPORTANT: DO NOT LAUNCH AURIA LE FIRST. Its default buffer size is incompatible for use with Audiobus. Launching Audiobus first avoids this problem.

Fix all the things

We have contacted WaveMachine Labs about this issue, and hope to have the situation resolved soon.


  • We're waiting for both Auria and Auria LE to become available before we list it officially (Apple is still reviewing Auria). We hope this will be soon. We'll keep you posted!


  • FYI, both Auria and Auria LE 1.06 have been approved, and are now available.
