Strange Attractor is a novel sound generator and effects processor based on chaos theory. At its heart is a feedback system which can spontaneously oscillate, or respond to incoming sounds, processing them into fractal sonic textures.

It generates a wide range of undulating sounds, controlled by touch, which slowly evolve in unpredictable ways. The sound is visualised as an ever-changing dynamic form.

Ratings and Reviews

Very Cool App, great support


Normally, I'd give 4 stars if its good but has no MIDI or Audiobus . But giving 5 for great support!
Had issues w/ no sound - Developer responded ASAP & pointed me to the fix - if one taps “Don’t Allow” microphone , when opening the system won’t ask again — ever. That can spell confusion and frustration for users who tapped the dialog away without reading it, and then discovered they’re unable to record audio. The trick is to open Privacy Settings for the device, and enable Microphone access for the app. The controls can be found in the system Settings app.

Mr. Mackenzie Deserves High Praise


This app (Strange Attractor) and VOCO are among my favorite audio apps in my collection. After a couple years of using them, I still manage to discover amazing new sounds and textures quite consistently.

I'm grateful for the thoughtfulness and effort invested. Hope to see more from this DEV... Someday.

Oscillation goodness


Very cool app. Small tweaks sets off some far out oscillating drones - spinning off into who knows what - deep space bass, glitches, timbres freaks. Would like more modulation, oscillation options, audio copy/paste, manual glitch, ability to name saved files. Lookin forward to updates
