A limiter is a human-made audio dynamics processor that automatically reduces gain when an input signal exceeds a set threshold, clamping the output to a maximum level to prevent overload or distortion. Parameters: (1) threshold — the signal level at which limiting begins, in dBFS or dBu; (2) attack time — the response time before limiting engages, typically 0–30 ms; (3) release time — how quickly limiting disengages after signal falls below threshold, typically 50 ms–2 s; (4) ratio — the compression ratio once threshold is exceeded, effectively infinite (∞:1) in hard limiting; (5) makeup gain — post-limiting amplification to restore perceived loudness. Mechanism of persistence: it persists as analog circuit topologies (VCA-based limiters, opto-limiters), as DSP algorithms in software plugins and hardware processors, and as a standard feature built into mixing consoles, digital audio workstations, and broadcast chain equipment.

Definition
Why it is in scope
A limiter is a human-made audio dynamics processor that reduces the gain of a signal when it exceeds a set threshold, preventing it from exceeding a maximum output level. Built to persist as a hardware unit, plugin, and built-in function of mixing consoles and digital audio workstations.

Limiting is an audio processing technique designed to reduce the dynamic range of an audio signal. It is built for the sake of audio-engineering applications: preventing overload, controlling peaks in mixing/mastering, and protecting equipment. Servant (limiting) points at master (audio-engineering) per Law 8d.
- cmrsb393a00miollhxpcc7bkzDEPENDS_ON →
Limiting operates on audio signals: it reduces the dynamic range of a signal by attenuating peaks. Remove the signal — the entity that limiting acts upon — and limiting has nothing to operate on. Its operation ceases. Per Law 8 removal test.

Limiting is DRC taken to its extreme: the same envelope-measuring, threshold-triggered variable-gain mechanism with an effectively infinite ratio and hard ceiling. DRC is the nearest kind — compression (data) is a different branch, and the limiter device already sits on this rung (limiter INSTANCE_OF DRC). Pinned sense: the dynamics-control process, not the hardware.

Removal test (Laws 2b/8b): limiting's accepted carve is 'a dynamics processor that automatically reduces gain when an input signal exceeds a set threshold, clamping the output to a maximum level.' The threshold is the defined crossing point its mechanism triggers on — without the threshold concept, 'exceeds' has no operative boundary: no trigger, no gain reduction, no clamping. The processor stops operating as a limiter. Consistent with accepted family precedent: limiter DEPENDS_ON threshold, compressor DEPENDS_ON threshold, noise-gate DEPENDS_ON threshold, de-essing DEPENDS_ON threshold are all on the map. Not purpose (8c): the threshold is not what the limiter is for, it is the condition its operation runs on.
