Limiter is a human-made audio signal processing technique that prevents signal amplitude from exceeding a specified threshold by reducing gain in real time. Parameters: threshold level (the amplitude at which gain reduction begins), ratio (typically infinite:1 for hard limiting), attack time (how quickly gain reduction engages), release time (how quickly gain returns), and knee shape (hard vs soft). Persistence mechanism: implemented as hardware limiter circuits, digital audio workstation plug-ins, broadcast processors, and loudness control algorithms; the technique persists through standardized signal-processing blocks, DSP code libraries, and industry practice of peak control. [formal: limitator | substrate: behavior | horizon: generations | explicit: yes | epoch: 0.04]

Definition
Why it is in scope
A human-made peak-control device built to persist as the standard final stage of mastering and broadcast delivery: a dynamic processor with an extreme compression ratio whose identity is the hard ceiling it enforces

Relations from this entry
- compressorINSTANCE_OF →
A limiter IS a specific kind of compressor: a compressor with an effectively infinite ratio that prevents the signal from exceeding a maximum level. Remove the concept of compression entirely and the limiter has no operating principle. A competent speaker would call a limiter 'a kind of compressor'.
- audio-processingSERVES →
Limiter is a dynamic range processor built and maintained for the sake of audio-processing: it clamps peak signal levels to prevent overload and shape audio. Servant points to master — limiter serves audio-processing.

A limiter is a signal processing component built to prevent signal amplitude from exceeding a threshold. It serves the broader signal processing practice by protecting downstream components and controlling dynamic range.
- cmrexhlpr0185g8vup2dwm91hDEPENDS_ON →
A limiter operates by reducing gain when signal amplitude exceeds a set threshold. Remove threshold as a concept/parameter and the limiter has no mechanism to determine when to compress — it stops functioning as a limiter. The removal test passes: threshold is the triggering parameter that defines limiter operation.

- clipper← INSTANCE_OF
A clipper IS a specific kind of limiter: it limits signal amplitude by harshly cutting (clipping) peaks at or above a threshold, as opposed to compression or limiting which reduce gain gradually. A competent audio engineer recognizes a clipper as a type of amplitude limiter.
