Apple today threw its weight behind  AudioBus, releasing an update to GarageBand that supports the tool for routing audio between applications.

Here’s what’s new in Garageband for iOS 1.4:

• Play and record music apps supported by Audiobus directly into GarageBand
• Turn off grid snapping to get finer control over region and note editing
• Fixes an issue that resulted in feedback while connecting 3rd-party audio accessories into the headphone/microphone jack

This is a major milestone for AudioBus. Many will interpret this as an endorsement by Apple of the app-to-app audio technology. And, while the arrival of Jack for iOS is major news, today’s GarageBand update, and Apple’s support, makes AudioBus the de facto standard for routing audio between apps on iOS. [Synthtopia]
