About

Recursion by folina

This app creates evolving echoes and feedback effects by mutating sound over generations. It offers unique control over timing, memory, and signal degradation for creative sound design. Explore subtle echoes to unstable ambient spaces.

Highlights
  • Self-mutating recursive delay
  • Generational sound evolution
  • Independent control over recursion depth
  • Continuous drift and instability
  • Smearing for evolving washes
  • Tear events for abrupt mutations

Recursion is a delay and feedback effect built around inherited mutation. In a conventional delay, a sound repeats. In Recursion, it evolves. Each generation passes through a changing recursive system before becoming the source for the next. Timing drifts. Memories smear together. Sudden tears disturb the signal. Those disturbances are then inherited by everything that follows. The result can move from subtle animated echoes and strange doubling to deteriorating rhythmic patterns, unstable ambient spaces, and dense halls of increasingly distant memories. Seven controls keep the process immediate. Memory determines the spacing between generations. Recursion determines how deep the family tree grows. Decay determines how long those generations survive. Smear, Drift, and Tear determine how faithfully—or badly—the signal remembers its past. Recursion isn't designed to be a perfectly behaved delay. It's designed to remember. Incorrectly. Features: Self-mutating recursive delay and feedback processing Each generation inherits changes from the generation before it Independent control over recursive depth, memory spacing, and decay time Continuous bounded drift and instability Smearing that transforms distinct echoes into evolving washes Tear events introduce abrupt mutations into the recursive history From subtle animated echoes to deeply unstable feedback structures Designed for drums, synths, guitars, vocals, sound design, and ambient processing. -------------------------------------------------------------------------------------- Behavior Note: Recursion is intentionally less predictable than a conventional delay. At high Mix settings, more of the immediate dry attack is replaced by the delayed recursive signal. Short sounds may therefore seem quieter as Mix approaches fully wet. Around 50% Mix is recommended when you want to preserve the original attack. Recursive processing can also produce occasional abrupt transient or crackle-like textures as generations mutate and interact, particularly with sustained material, aggressive settings, or parameter movement. These behaviors are part of Recursion's unstable character.

About

FreezeSlice

Highlights
  • Freeze multiple audio layers
  • Rhythmic slicing with 16-step patterns
  • Texture and space manipulation (smear, shimmer, grit)
  • Stereo field spreading and drift effects
  • 8 performance pads with latch/momentary modes
  • MIDI control and mapping
  • Visual feedback with glowing ice ring

FreezeSlice turns any sound into an endless, playable drone. Strum a chord, play a keyboard voicing or sing a note, tap ADD, and FreezeSlice holds it at its original pitch for as long as you like. Then chop it in time with your song, color it, spread it across the stereo field, and save it to pads you can fire during a performance. FreezeSlice is an AUv3 audio effect built for live looping and performance. Load it on any channel in your favorite AUv3 host. FREEZE - Freeze up to 4 live layers on top of each other - ADD stacks a new layer; REPLACE crossfades to a new one; RELEASE melts everything away - Set each layer's level, or melt just one layer - Drag the Swell curve to shape how freezes bloom in and fade out (up to 10 s in, 20 s out) SLICE - Chop the frozen sound to the host tempo with a 16-step pattern - Rates from 1/4 to 1/32, including triplets, and 1 to 16 steps - Pattern presets: Trance, Eighths, Offbeats, Gallop, Dotted, Stutter, Half and Build - Shapes both volume and a filter, with Depth, Smooth, Filter and Resonance - Tap the ring to edit steps while it plays TEXTURE AND SPACE - Smear blurs a clear chord into a soft cloud - Shimmer adds airy upper partials: Octave, Octave + Fifth, or Sparkle - Grit crushes the sound from a lo-fi edge to broken radio - Width spreads your layers across the stereo field - Drift makes the drone slowly wander in tone, pan, pitch and level, so held sounds feel alive PADS - Save stacks of frozen layers to 8 pads - Latch, Momentary or Hit mode on every pad - Latch and Momentary pads take over the ring with a smooth crossfade; Hit pads blast on top - Per-pad volume, slicer switch and Hit Decay - Swipe a pad to clear it PRESETS - Save every setting, with or without the audio on your pads - Pads are also saved with your host session PLAY IT YOUR WAY - MIDI notes 36 to 43 play pads 1 to 8, with velocity - MIDI CC 80 to 83 for Add, Replace, Release and Stop - Every control can be mapped to host widgets, pedals and controllers - Built-in MIDI monitor shows exactly what's arriving SEE WHAT YOU HEAR - A glowing ice ring shows every frozen sound, the slicer playhead and a live stereo map of your layers - Full-screen layout for iPad, plus a compact layout when docked in your host - Built-in user guide Made by Mr. Brad's Music for live looping on stage. Requires an AUv3-compatible host app.
