Audiobus Teaser – ‘This Just Worked’

Audiobus update: ‘This just worked”.

Audiobus – a system for routing audio between iOS apps – has been approved by Apple, and is now in testing with an initial round of developers. This is so there will be apps to use with it with when it is released.

Apps officially supporting Audiobus now includes:

  • SoundPrism Pro
  • Loopy
  • NLog Synth Pro

What Is Audiobus & How Will It Change Mobile Music Making?

Audiobus has been one of the most talked about new music technologies since it was announced earlier in this year.

One of the key limitations for music apps on iOS has been the challenges of working with audio from multiple music apps ‘in the box’. Audiobus – a new option for routing live audio on iOS – promises to change that.

Since the initial Audiobus announcement, there’s been debate over whether iOS 6 would derail the project, skepticism that it would get approved by Apple and confusion about what it is. Even now that Audiobus has been approved by Apple, there’s still confusion over how it will work and what it means for iOS music making.

To address this, we talked with developer Sebastian Dittmann and beta user Tim Webb.

Audiobus: The Developer’s View

Sebastian Dittmann is one of the founders of Audanika, the creator of SoundPrism Pro. Audiobus is a joint venture between Dittmann and Michael Tyson of A Tasty Pixel, creator of the iOS looping app Loopy.

We asked Dittmann about Audiobus, how it came about and how he sees it fitting into the future of mobile music making.

Synthtopia: To start off, Sebastian, what is Audiobus? What is your vision for Audiobus and how it will be used?

Sebastian Dittmann: Audiobus is a standalone app and an API for other developers to include in their own apps. Audiobus allows live audio streaming between apps, providing for the ability to use apps together like modules in a studio.

It’s the virtual ‘cabling’ that ties everything together.

We envision a whole new way of making music, bringing together the work of many different developers. We also envision a whole new class of music apps that provide audio processing capabilities to other apps.

Asturias by Albeniz, played on SoundPrism Pro by David Gatzsche, one of the co-founders of Audanika:

“From our education, we are used to be confronted with theories and after that we are told where to apply the acquired knowledge,” notes Audanika’s Gabriel Gatzsche.

“But life teaches us in the opposite way: typically we first make experiences and after that we find the formulas that describe what we experienced.”

In this performance, SoundPrism is being used as a MIDI controller, via USB.
