Audiobus is all about connecting apps, which requires apps with built-in support. So, one surprising and encouraging feature – Audiobus will make it easy to discover which apps are compatible. (See also: notifications, below.)

Use a great effect app to process another app. Record your favorite app in another tool. Make apps work together, and maximize the potential of your iPhone, iPad, or iPod touch. At last, Audiobus promises the ability to take the constellation of apps appearing on Apple mobiles and use them together, easily. We’ve known why this was cool, and we knew it was coming – see our in-depth preview and explanation of workflow..

Now, we know when, and to which apps. Audiobus’ developers have revealed next Monday December 10 as the official launch date. Also, we’re seeing some new screens – prepared for CDM – that show that it’ll be really easy to discover which apps work, or even to sign up for notifications on when apps are available.

All you need to run Audiobus:

  • The US$9.99 Audiobus app. (Given the massive development effort behind this thing, that seems a good way to support the creators – and the app itself is rather beautiful.)
  • An iPad, iPhone, or iPod touch running iOS 5.0 or later. (The new iPod touch, for instance, looks like a great handheld music machine for those who don’t want a phone contract.)
  • Compatible apps (a lot of your favorite apps will just add support in updates).

The heart of Audiobus: routing different apps allows you to combine sources, effects, and recording/hosts. All images courtesy Audiobus.

Audiobus has also revealed launch apps:

Funkbox (input slot)
JamUp (effects slot)
JamUp Pro (effects slot)
Loopy (input and output slot)
Loopy HD (input and output slot)
MultiTrack DAW (output slot)
NLog MIDI Synth (input, effects and output slot)
NLog Synth PRO(input, effects and output slot)
Rebirth for iPad (input slot)
SoundPrism Pro (input slot)
Sunrizer Synth for iPad (input slot)

Thumbjam and Drumjam are awaiting Apple App Review; Moog Animoog and Wavemachine Labs Auria support is coming, awaiting completed implementation.

Support is ramping up gradually. 700 people entered to become developers, but only 25 will get the SDK in the next round. (CDM will be looking at the SDK to give users and developers alike a preview.)

One reason: Audiobus’ creators want to make sure that these apps get feedback and that developers are approved by App Review. They say things will go public in the coming months.

More videos and details are coming from Audiobus – and hopefully from us here, too. In the meantime, here’s a look at the Audiobus app. See you next Monday.

Developers can notify you when apps become compatible – crucial given that Apple has to approve new apps, which Audiobus’ creators say is typically the longest delay, not development.
