Audio Gating

PERF can apply its perforation patterns to live audio input, not just generated MIDI. This turns PERF into a rhythmic gate — the same mathematical structures that create holes in MIDI sequences can carve gaps in audio signals.

​
How It Works

PERF accepts up to 12 audio input channels. Each channel is paired with a layer’s perforation engine. When a layer’s perforation pattern says “remove this event,” the corresponding audio channel is gated (silenced). When the pattern says “keep,” the audio passes through. The result is audio that has been rhythmically sculpted by Euclidean distributions, Fibonacci patterns, cellular automata, or any of PERF’s 7 perforation methods.

​
Setup

  1. Route audio into PERF’s input bus (up to 12 channels)
  2. PERF’s perforation engines gate the audio in real-time
  3. Gated audio appears on PERF’s output bus
The perforation amount, method, and layer interaction settings all affect the audio gating behavior, just as they affect MIDI generation.

​
Use Cases

  • Rhythmic slicing of pads, drones, or sustained textures
  • Mathematical stuttering of vocal or melodic content
  • Polyrhythmic gating across multiple audio sources using different layers
  • Live performance gating synchronized to DAW transport
Audio gating uses the same perforation engines as MIDI generation. Changing the perforation method or amount affects both the MIDI output and the audio gating simultaneously.
