A few months back we told you about AudioBus – an app being developed for iOS allowing live app-to-app audio streaming. We have just learned that, this morning, Apple finished reviewing the first version of Audiobus, and it has been approved!

AudioBus will launch later this year, along with a series of app updates from those third party developers that have had early access to the SDK.
“We’ve been working with a small group of third party developers that we already have a close connection with because we want to make sure that those apps can serve as examples for all the other developers (currently more than 450) for how to implement Audiobus.
Once our initial community of developers have finished the Audiobus integration, we’ll be all launching together and opening up the SDK to the public.”
Audiobus is a local (and network) communications channel for sending live audio, like the audible output of a synthesizer app, or the output of a guitar amp effects app, for example.
For more information about AudioBus, or if you’re an app developer and would like to sign up for the SDK beta programme, then check out the FAQs and blog.
I hope this is reasonably priced and well supported by other App developers – if it delivers what I think it should, it will be a real game changer!
Just read this post on another forum and thought I’d copy/paste to clarify a few things about Audiobus!
“Hi folks,
Co-creator of Audiobus here.
Thanks to [other forum] for mentioning Audiobus!
I just want to clarify that Audiobus is NOT a mixer or multi-track recording tool. It can be used to connect mixers and multi-track recording apps if they support Audiobus though.
Also: Audiobus is NOT going to be be released in the next few days. Some first group of developers we give access to the technology still need to add it to their apps (and release updated versions of them on the App Store) and we need to run extensive betatests.
Best,
Sebastian”
@Stephen K: Your right, I’ve just edited the story to remove reference to this. It looks like it was planned to include a multitrack recorder but they have now decided not too, as that functionality will be included in supported third party apps. The AudioBus FAQ was changed yesterday to clarify. Thanks for pointing this out!
