Air is a generative audio-visual work created by musician / software designer Peter Chilvers and Irish vocalist Sandra O’Neill.  Based on concepts developed by Brian Eno, with whom Chilvers created Bloom, Air assembles vocal and piano samples into a beautiful, still and ever changing composition, which is always familiar, but never the same.

Air features four ‘Conduct’ modes, which let the user control the composition by tapping different areas on the display, and three ‘Listen’ modes, which provide a choice of arrangement.  For those fortunate enough to have access to multiple iPhones and speakers, an option has been provided to spread the composition over several players.

Recommended for headphones and external speakers.

"Air is like 'Music for Airports' made endless - which is how I always wanted it to be" - Brian Eno

Wow, an update after five years!


Okay, it's nothing earth-shattering, but still - thank you so much for thinking of us supporters from so long ago. Sure, it would be nice to have Audiobus support, or different moods, or ? Perhaps some other day. In the meantime, a little update is much appreciated.

Great sounds, could use more control


I am a huge fan of "Ambience" and this doesn't dissapoint, but I feel like there should be a bit more user control. The sounds are fantastic, exactly what you would want and expect. They are "airy" but very present to the listener. You can either let the app take control of the sound making (which seems to turn out some pretty cool stuff), or you can manually control the sound creation process. Essentially, you can start a sample and it will run it's course. Naturally layering these samples if where all the fun comes in, but I couldn't help feeling like there could be more done in the UI. The iphone's multitouch capability begs to be used and a simple "tap here, tap there" app leaves a lot to be desired. I'm sure that a lot of time and work was put into crafting this app but I think that gesture would make an awesome contribution to the UI. I would like to be able to swipe to fade in and out effects or to dry up the reverb or even to fade in and out the sounds. An option to have the piano looping (similarly to "Ambience") would be great and it would be very cool if on the "Listen" mode you could adjust the frequency of changes, so that the piano could play more often or less often. Lastly, it would be great to see a min-max idea to randomization of the frequncy of when sounds are triggered.

I think this is a cool app with potential and would like to see it supported with future updates.

Depends what you want out of it.

Loved Bloom (5 stars) and loved Trope even more(5+ stars). Air somewhat disappointed me, although only by comparison with the first two Opal releases. In and of itself, the music is very soothing and the graphics are nice. What I found disappointing was that I was expecting this to be more of an "instrument" like Bloom and Trope. Air offers less control and variety of notes than it's predecessors. For instance, you have little to no control over the pitch of the samples. And the piano parts consist of two consecutive notes thus creating limitations of when you can trigger a sample in a graceful rhythm. To be fair, to get the most out of this app, don't judge it against Bloom or Trope; it is a somewhat different animal. If you are looking for a tranquil listening experience that allows some manipulation, this release would make a nice addition to your collection. The sounds are great, but after my experience with Bloom and Trope, I found this experience to be slightly frustrating.
