How It Works
Technical view
The current reverse family does not reverse buffered audio. Instead, it builds a reverse-like smear from two forward delay taps, low-passing the primary delayed layer and mixing that texture against the dry phrase. `motion` stretches the tap times, `tone` opens the low-pass filter, and the declared `shape` control is inactive. There is no reversed buffer playback in the current implementation.

Signal Path
Compiled preview chain
Preview source: An internally generated picked-string phrase is widened to stereo with a 19-sample right-channel delay before it hits the current looper or glitch core.

Preview source
An internally generated picked-string phrase is widened to stereo with a 19-sample right-channel delay before it hits the current looper or glitch core.
Effect core
Two forward delay taps shaped into a reverse-like smear and blended against the dry 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
- two forward delay taps
- low-pass shaping on the darker primary delayed layer
- dry / reverse-like 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 between the dry preview phrase and the reverse-like delayed texture.
- output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
- motion: Sets the lengths of the two forward delay taps used to fake the reverse-like texture.
- shape: Declared in the shared control set but unused in the current preview code.
- tone: Sets the low-pass cutoff on the darker primary delayed layer.
Code-backed analysis
The generated description is tied to the active helper blocks and routing found in the current DSP.

Controls
Audible controls in this DSP
Blends between the dry preview phrase and the reverse-like delayed texture.
Higher settings emphasize the smeared delayed layer over the direct phrase.
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 lengths of the two forward delay taps used to fake the reverse-like texture.
Stretches the smear into longer pre-echo style swells as it increases.
Declared in the shared control set but unused in the current preview code.
Changing it currently has no effect on the sound.
Sets the low-pass cutoff on the darker primary delayed layer.
Makes the reverse-like wash darker at low settings and more open at high settings.
Analysis
Code-derived notes
Current implementation shares the same reverse-like forward-delay architecture across Reverse Looper, Reverse Half-Speed Looper, and Reverse Capture, and the declared shape control is inactive. Reverse Looper does not yet reverse captured audio.
