In an unusual move of supporting third-party APIs, Apple has released an update to GarageBand for iOS adding the ability to receive audio from other iOS apps via Audiobus. Designed to facilitate mixing audio across multiple apps on a single iOS device, Audiobus is a third-party app that other iOS music apps can interface with to send and receive audio with other compatible apps. The addition of Audiobus support in GarageBand now allows users to record and sequence sounds from a wide variety of other Audiobus supported apps, such as Amplitube, Music Studio, AmpKit, BeatMaker, and dozens more.
The latest GarageBand update also adds the ability to disable grid snapping for finder editing control and resolves an issue with connecting third-party audio accessories to the 3.5mm headphone/mic jack. GarageBand 1.4 is available from the App Store for $5.
