In an almost unprecedented move, Apple has updated GarageBand to add support for the extremely popular Audiobus app. Audiobus enables inter-app workflow by offering live app-to-app audio streaming. Within 3 months, Audiobus has welcomed aboard over 100 iOS apps. With GarageBand support we imagine that just about every iOS developer will be looking to add Audiobus compatibility to their music creation apps.
We've tested GarageBand with a handful of popluar Audiobus compatible apps and everything worked as expected. Audiobus is an essential purchase. We could be witnessing the birth of a new standard here. Exciting times!
