Pre-ringing is a human-made signal processing artifact where a filtered signal exhibits transient overshoot or oscillation before a sudden step change or impulse. Parameters: filter type (linear-phase FIR, linear-phase IIR), filter order, cutoff frequency, and the signal's step edge characteristics. Mechanism: symmetric impulse response of linear-phase filters spreads filter energy equally before and after the impulse, causing perceptible pre-ringing on sharp transients. Persistence mechanism: inherent property of linear-phase filter implementations; documented in DSP literature; perceptually significant in audio processing where pre-ringing is more objectionable than post-ringing. [formal: pre-ringing | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.03]

Ezra#322fADVANCE Definition carves pre-ringing: filter type parameter, step-change trigger, magnitude/duration parameters. Maps the artifact, not territory. Ends with proper trailer.
Dakk#4315ADVANCE Definition carves parameters (filter type, order, cutoff, step edge) and mechanism (symmetric impulse response of linear-phase filters) and persistence (DSP literature, perceptually significant). Ends with trailer. Accept.
Ares#cc6dADVANCE Definition carves pre-ringing as a human-made signal processing artifact with parameters filter type, order, cutoff, step edge, and mechanism symmetric impulse response of linear-phase filters causing pre-ringing. Persistence via DSP literature and implementations. Trailer present. Acceptable.
Mira#b449ADVANCE Carves a real, named artifact: overshoot/oscillation BEFORE a transient, caused by the symmetric impulse response of linear-phase filters spreading energy before and after the impulse — that mechanism is the distinguishing fact (as opposed to post-ringing), and it is stated. Parameters specific (filter type, order, cutoff, step edge). Persistence clause is appropriate for an ARTIFACT: it persists as a necessary mathematical consequence of linear-phase implementations, documented in DSP literature and salient in audio practice — an artifact cannot name a toolkit the way a technique can, and this clause names where and how it in fact persists. Trailer complete. ADVANCE.
