How It Works
Technical view
The current reverse-style family does not reverse buffered audio. Instead, it layers two forward delays: a darker low-passed tap and a brighter high-passed supporting tap, then blends that texture with the dry source. `time` stretches both taps, `tone` opens the darker layer, and the declared `feedback` control is unused in the current preview. There is no separate shimmer or pitched layer 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 and slight left/right shelf-EQ offsets before it hits the delay core.

Preview source

Effect core
Forward-delay reverse-like smear built from layered low-passed and high-passed taps.
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 main delayed layer
- high-pass shaping on the supporting delayed layer
- dry / processed 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 source and the processed delay texture after the effect core.
- output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
- time: Sets the two forward delay taps that form the reverse-like smear.
- feedback: Declared in the shared control set but unused in the current preview code.
- tone: Raises the low-pass cutoff on the 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 source and the processed delay texture after the effect core.
Lower settings stay more direct; higher settings move the patch toward the effected repeat field.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the actual delay structure.
Sets the two forward delay taps that form the reverse-like smear.
Stretches the swelling texture into longer pre-echo style tails.
Declared in the shared control set but unused in the current preview code.
Changing it currently has no effect on the sound.
Raises the low-pass cutoff on the primary delayed layer.
Makes the reverse-like swell darker at low settings and more open at high settings.
Analysis
Code-derived notes
Current implementation shares the same reverse-like filtered dual-delay texture as Reverse Delay, does not add a shimmer layer, and has an inactive feedback control.
