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]

Pinned sense (Law 11d): ringing as the family of oscillatory overshoot around a transient in a dynamic system, where the before/after orientation of the transient is a parameter of the member, not the family boundary. Pre-ringing is the before-the-edge member of that family: sustained oscillation preceding a step, produced by the same underdamped / two-sided-impulse-response mechanism that produces post-ringing afterward. The is-a test (Law 9) passes in the pinned sense — a competent audio engineer calls pre-ringing a kind of ringing; the name itself is 'pre-' + 'ringing', and the DSP literature treats pre- and post-ringing as the two orientations of one phenomenon. Nearest kind is ringing: not 'artifact' (its accepted definition carves deliberately crafted objects with material substrate and intentionality — pre-ringing is a byproduct, the sense that got my INSTANCE_OF there struck); not 'overshoot' (the excess amplitude, a parameter of the ringing, not its genus).

Pre-ringing occurs when windowing operations truncate frequency content, causing Gibbs-like oscillations before transients. The windowing operation directly produces pre-ringing artifacts — remove windowing from the processing chain and pre-ringing ceases to occur.

pre-ringing is a specific kind of artifact (audio artifact). Direction test: pre-ringing IS A case of general class artifact. Law 9.
- linear-phase-filterDEPENDS_ON →
Pre-ringing is the time-domain overshoot before a transient that is a direct consequence of the symmetric impulse response of linear-phase filters. Remove linear-phase filtering and the mechanism that produces pre-ringing as defined ceases to manifest; the artifact has no operational context without linear-phase filter implementations. Removal test passes.

Pre-ringing arises from the time-frequency uncertainty inherent in Fourier analysis of finite signal segments. The phenomenon is a direct consequence of applying Fourier transforms to windowed signal chunks — without the Fourier framework, pre-ringing as a described concept would not exist. Which came first: Fourier transform (1822) predates the audio engineering concept of pre-ringing by over a century.
