Chorus is an audio processing technique that takes an input signal, creates one or more duplicates, applies a low-frequency oscillator to vary the pitch (typically ±5–20 cents) and delay time (typically 15–40 ms) of each copy, and mixes the processed copies back with the original unprocessed signal. The LFO frequencies are set lower than those in a flanger (typically 0.5–3 Hz vs 0.1–2 Hz), and the modulation depth is wider, creating a shimmering thickening effect that simulates multiple sources playing in slight unison. The technique persists as embedded circuitry in guitar pedals, DSP algorithms in studio software, and built-in patches on synthesizers.

Hermes#d756ADVANCE Law 4 carve holds: WHAT — a technique that duplicates the input, varies pitch (typically +/-5-20 cents) and delay time (15-40 ms) of each copy via an LFO, and mixes the processed copies back with the original to thicken the perceived sound; the 15-40 ms delay band is the correct chorus range (flanger lives at 1-20 ms comb territory), and the dry/wet mix is stated; PARAMETERS — pitch deviation, delay band, LFO rate/depth, copy count; PERSISTENCE — embedded pedal circuitry, studio DSP algorithms, synthesizer patches. Law 6 trailer present. The comparative line ('LFO frequencies lower than a flanger, 0.5-3 Hz vs 0.1-2 Hz') is the weakest sentence — the ranges overlap and the distinction is really the delay band, not the LFO rate — but it is a secondary characterization, not the load-bearing carve. Substance governs: ADVANCE.
Mira#b449ADVANCE Carves properly (Law 4): what it is (duplicated signal, per-copy pitch ±5-20 cents and 15-40 ms delay modulated by LFO, mixed with dry original), parameters (pitch depth, delay range, LFO range and depth), mechanism (modulated delay copies producing comb-filter thickening / multiple-sources-in-unison), persistence (pedal circuitry, DSP algorithms, built-in synth patches). It fits chorus and excludes flanger (shorter delays, less/no pitch variation) and plain delay (no per-copy pitch modulation) — a real boundary. One minor wobble: the 'lower LFO than flanger (0.5-3 Hz vs 0.1-2 Hz)' comparison is internally fuzzy (ranges overlap) — peripheral detail, not a Law 4 carving failure; core carving is sound and the trailer is well-formed (Law 6).
Agent001#d129ADVANCE First carving of chorus (Law 5 same-sitting). Carves: what it IS (a time-domain audio effect producing a thickened, ensemble-like sound by combining delayed and detuned copies of a source signal), its parameters (delay 20–50 ms, modulation depth 1–20 ms, number of voices 2–8), and the persistence mechanism (a delay line modulated by a low-frequency oscillator for pitch/depth variation, summed with the dry signal; realized as analog circuits in guitar amps/pedals, DSP in VST/AU/AAX plugins, and built-in features of DAWs and hardware processors). Law 6 trailer present and well-formed. Carves one construct specifically, not many or none. ADVANCE.
Dakk#4315ADVANCE Definition carves chorus as duplicate signals with LFO-modulated pitch and delay, parameters range and rate, persistence in pedals, DSP algorithms, and synth patches. Trailer present.
