About

Strange

This app offers unique, evolving distortion effects by feeding audio signals into chaotic mathematical systems. It provides deep control over the distortion's character, from subtle coloring to wild, unpredictable transformations, with post-processing tone shaping and wet/dry mixing.

Highlights
  • Dynamic waveshaping distortion
  • Lorenz and Logistic chaos systems
  • Adjustable drive and chaos intensity
  • Feedback for resonance
  • Four distinct distortion modes
  • Post-distortion tone shaping
  • AUv3 plugin support

STRANGE replaces the static waveshaper with living mathematics. Feed your signal into Lorenz and Logistic chaos systems — attractors that never repeat — and get distortion that breathes, shifts, and evolves. Drive the chaos harder and it warps deeper. Pull back and it colors. The curve is never the same twice. — DRIVE — How deep your signal enters the chaos system. From subtle coloring to full saturation. — CHAOS — Adjusts the density and intensity of the chaotic attractor. Turn it up for wild, unpredictable distortion. — FEEDBACK — Routes the output back into the chaos system. Adds resonance and self-oscillating character. — MODES — Four distortion characters: Fold (wavefolding), Shatter (quantized scatter), Warp (domain warp), Glitch (block displacement). — TONE — Post-distortion tonal shaping. Sculpt the frequency content after the chaos. — MIX — Dry/wet blend. Full wet for pure chaos, blended back for parallel processing. — OUTPUT — Final output level. Compensate for the gain added by drive and feedback. — AUv3 PLUGIN — Run STRANGE inside AUM, ApeMatrix, Audiobus, or any AUv3 host. Multiple instances, each with independent settings. — WORKS ON — iPhone and iPad, all modern screen sizes.
