How It Works
Technical view
The current `Octave Looper` does not record and loop audio at an octave offset. Instead, it mixes a straightforward dry delay tap with a separately synthesized octave phrase. `motion` changes the delay-tap length, `mix` sets the overall wet amount, and the declared `shape` and `tone` controls are inactive.

- waveshaping / saturation
- delay processing
- oscillator / LFO modulation
- DC blocking
Signal Path
Compiled preview chain
Preview source: An internally generated picked-string phrase is widened to stereo as the dry source, and the current effect also layers a separately synthesized held or slowed phrase rather than capturing the live input into a loop buffer.

Preview source
An internally generated picked-string phrase is widened to stereo as the dry source, and the current effect also layers a separately synthesized held or slowed phrase rather than capturing the live input into a loop buffer.
Effect core
Dry phrase plus one delay tap and a separately synthesized octave phrase.
Signal path
The static waveform and the live player both reflect this compiled signal chain.
- internal picked-string demo phrase
- stereo spread with a short right-channel delay
- delayed dry repeat
- separately synthesized octave phrase
- dry / repeat / octave blend
- DC blocker
- output gain trim
- final tanh limiter
Controls that matter
These are the currently active controls detected in the FAUST source for this effect.
- mix: Blends the dry phrase with both the delayed dry tap and the synthesized octave layer.
- output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
- motion: Sets the delay time of the added dry repeat that sits beside the synthesized octave phrase.
- shape: Declared in the shared control set but unused in the current preview code.
- tone: Declared in the shared control set but unused in the current preview code.

Controls
Audible controls in this DSP
Blends the dry phrase with both the delayed dry tap and the synthesized octave layer.
Higher settings make the delay-like repeat and the octave layer more obvious.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the actual loop, freeze, or glitch structure.
Sets the delay time of the added dry repeat that sits beside the synthesized octave phrase.
Moves the delay-like repeat from tighter to longer spacing.
Declared in the shared control set but unused in the current preview code.
Changing it currently has no effect on the sound.
Declared in the shared control set but unused in the current preview code.

Analysis
Code-derived notes
Current implementation combines a simple delay tap with a fixed octave phrase rather than recording and replaying a loop, and the declared shape and tone controls are inactive.
