Wavefield

A stereo parallel bandpass filter bank for iOS. Select 8, 16, 24, or 32 active bands, animate their gains with seven procedural generators, or draw an eight-point Sculpt curve and sequence scenes into a chain. Wavefield runs as an AUv3 effect or standalone app.

Quick Start

  1. Open Wavefield standalone and choose EDIT, or add it as an AUv3 audio effect in a compatible host.
  2. Send audio through the effect and choose one of the eight generator modes.
  3. Choose Bands, then set Depth, Q, and Smooth to establish the spectral shape.
  4. For a procedural mode, adjust Speed, Sync, and Direction to control its movement.
  5. Blend the result with Wet/Dry, then set Input Drive, Output, and Output Drive.
  6. Use PRESETS to save and recall effect settings; Sculpt scenes and chains remain separate from presets.
Tip: Lower band counts create isolated resonances; higher counts produce dense spectral washes.

Core Controls

Bands
Choose 8, 16, 24, or 32 parallel filters
Depth / Q / Smooth
Set gain intensity, resonance, and gain-smoothing time
Speed / Sync
Run procedural motion freely in Hz or lock it to tempo
Direction
Move left, right, or ping-pong across the spectrum
Spread
Offset right-channel scan phase; individual bands do not pan
Freeze
Hold procedural scan phase and the exact audible gains

Eight Generator Modes

Ripple
Fluid seeded interference waves with correlated turbulence
Comb
Rigid repeating spectral teeth with independently wandering groups
Terrain
Bipolar multi-scale cyclic landscapes
Orbit
Sparse spotlights following seeded counter-rotating paths
Cascade
One directional travelling spectral conveyor
Chord
Pitch-correct harmonic clusters on the logarithmic frequency axis
Drift
Correlated cyclic random motion with controllable temporal inertia
Sculpt
Eight manual gain points interpolated across the active filters

Sculpt Your Own Curve

  • Drag the Motion display to shape eight gain points from low to high frequencies.
  • Use broad Low, Mid, and High trims to reshape the curve without changing saved Scene curves.
  • Capture up to 16 curves in Scene slots and arrange up to 64 steps in a Chain.
  • Choose each step's Scene, duration, and Hold, Linear, or Smooth easing.
  • Enable playback and optional looping for timed curve changes.
  • Sculpt is static without a playing chain; its Speed, Sync, Direction, Freeze, and Spread controls are hidden.

Common Questions

  • No effect: Confirm audio is routed through Wavefield, raise Wet/Dry and Depth, and check that the active bands are not muted.
  • The motion is too subtle: Raise Depth or Q, choose fewer bands, or increase the filtered Wet/Dry level.
  • Procedural motion will not move: Turn off Freeze. In sync mode, start the standalone transport or the host transport.
  • Sculpt is not animated: Sculpt is static until an enabled chain plays. Build a scene chain when you want timed curve changes.
  • No sound or live spectrum: Wavefield is an effect, not an instrument. Route audio into it to hear processing and see live IN/OUT spectra.
