Developer Batuhan Bozkurt has released Circuli – an ambient sound generator for iOS.


  • Circles grow at a constant rate.
  • No two circle can overlap.
  • Bigger circle pushes and shrinks smaller circle when in contact.
  • A circle “pops” and makes a sound when its boundary intersects with the center of another circle.
  • The pitch of the sound is determined by the position of the circle on the background. Bigger the hole, higher the pitch.
  • The envelope of the produced sound is determined by a number of parameters including final circle size and time of interaction between two involved circles.

Circuli is $.99 in the App Store.

  1. I wish this would send midi out so it could trigger some better sound sources. Otherwise it looks pretty neat.
