audio-effect

Audio-effect is a specific human-made technique or device that intentionally alters a sound signal, which is a particular operation within the human-made map of audio-processing. The audio-processing definition explicitly lists effects (reverb, delay, modulation, distortion) as processing types, making audio-effect the nearest kind rung for those concrete effect instances. Direction specific→general per Law 9, nearest kind per Law 11e.

equalizer is a specific kind of audio-effect: it alters the tonal character of a sound by independently adjusting the amplitude of specific frequency bands. This is intentional sound modification through frequency-domain processing — a core audio-effect that shapes how a sound is perceived spectrally.

Compressor is a specific kind of audio effect: it reduces the dynamic range of a signal by automatically lowering gain when the signal exceeds a threshold. Direction: compressor (newer, 1940s recording technique) INSTANCE_OF audio-effect (older, foundational). Nearest kind per Law 11e.

A noise-gate is an audio-effect that attenuates or mutes a signal when its level falls below a set threshold. Like distortion and equalizer, it is a specific kind of audio processing device/algorithm applied to an audio signal to modify its character — specifically by removing signals below threshold. A competent speaker would call it 'a kind of audio effect'.

Spectral gating is a specific kind of audio effect in the pinned sense: the accepted carve of audio-effect is 'a signal processing technique or device that intentionally alters a sound signal to change its perceptual character, creating a version distinguishable from the unprocessed source.' Spectral gating intentionally alters a sound signal (per-band threshold attenuation) and the processed version is plainly distinguishable from the source. Precedent in the accepted record: noise-gate INSTANCE_OF audio-effect (a time-domain gate) is accepted; spectral gating is the same gate kind operating per-band in the frequency domain. Nearest-kind test (Law 11e): the direct parent for a named effect is audio-effect; its noise-reduction role is already carried by the separate accepted edge spectral-gating INSTANCE_OF noise-reduction, so this edge is not a derivable leap but the effect-kind rung. Filed from the canonical node; the duplicate spectral-gate node's parallel edge was struck as a duplicate.

distortion is a specific kind of audio-effect: it intentionally alters sound by clipping or overdriving an electronic signal to add harmonic content. As an audio-effect, it is a tool for deliberate sound modification through signal processing — the core purpose of any audio-effect.

Ducking is a specific kind of audio effect: it intentionally alters the perceptual balance of a mix by dynamically attenuating one signal in response to another, creating a version distinguishable from unprocessed source. Competent engineers call ducking an audio effect. Nearest kind is audio-effect.

Send effect is a specific kind of audio effect: it is an effect routing configuration that processes audio via parallel split and mix, altering signal character. A competent engineer classifies send effect as a form of audio effect. Nearest kind per Law 11e is audio-effect.

A phaser is a specific kind of audio effect: it intentionally alters a sound by mixing a signal with its phase-shifted self through all-pass filters to produce a sweeping comb-filter 'swoosh.' Nearest kind is audio-effect (Law 11e). Direction: specific (phaser) -> general (audio-effect).

Reverb is a specific kind of audio effect: it intentionally alters a sound signal in a perceptible way — adding the perceptual impression of an enclosed space via a dense, decaying tail of reflections — which is the carve in the target's definition ('intentionally alters a sound signal in a perceptible way, distinct from the source'). A competent audio engineer calls reverb an effect. Nearest kind per Law 11e: audio-effect is closer to reverb than the broader signal-processing, which the ALREADY ACCEPTED reverb INSTANCE_OF signal-processing edge (ge49402fef) treats as the general kind; audio-effect sits between reverb and signal-processing, and the older rung will be retired as SUBSUMED without penalty once the ladder completes (Law 11e). Direction tested: reverb is the specific, audio-effect the general (Law 9).

Frequency modulation is a specific kind of audio effect: it intentionally alters a sound signal by varying instantaneous frequency, fitting the audio-effect carve. Nearest kind per Law 11e.

A wah-wah is a specific kind of audio effect: it intentionally alters a sound by sweeping a bandpass filter's center frequency to produce a vocal-like 'wah' sound. Nearest kind is audio-effect (Law 11e). Direction: specific (wah-wah) -> general (audio-effect).

tremolo is a specific audio effect that produces a regular oscillation of volume (amplitude) at a low frequency. A competent speaker calls tremolo an audio effect.

Same constitutive-element test as insert-effect (which I just judged): send-effect's accepted definition is a routing configuration in which a signal is split to feed an effect unit in parallel, the effect's output mixed back with the dry signal. Law 8b removal: strip the audio effect unit and the send is a bare tap with nothing to process and nothing to return — a dead patch, not a send-effect. Not identity (a routing configuration is not an effect; the effect can run without this particular send), not INSTANCE_OF (a configuration is not a kind of effect). The configuration operates only while an effect unit occupies its return path.

Flanger is a specific kind of audio effect: it mixes a signal with a delayed copy of itself, sweeping the delay time to produce a comb-filter 'swoosh.' Direction: flanger (newer, 1960s effect) INSTANCE_OF audio-effect (older, foundational). Nearest kind per Law 11e.

Parallel compression is a specific kind of audio effect: it intentionally alters a sound signal by blending compressed and dry versions to change dynamics. Specific->general holds, nearest kind is audio-effect.

Removal test (Law 8b): remove audio effects and the insert configuration stops operating — a series connection with no effect unit in it is a bare pass-through, not an insert-effect. The configuration is not identical to the effect (not identity, Law 8c) and it is not a purpose statement: the effect unit is the operative content the configuration exists around, the same shape as screwdriver DEPENDS_ON screw. Direction pinned: from=insert-effect (the configuration), to=audio-effect (the kind it requires).

Wah-pedal is a specific kind of audio effect: it intentionally alters a guitar signal by sweeping a bandpass filter's center frequency, producing a distinctive timbral change. A competent audio engineer would call a wah-pedal an audio effect. Nearest kind per Law 11e: audio-effect (between wah-pedal and the broader signal-processing). Direction: specific→general per Law 9.

Ring modulator is a specific kind of audio effect: it intentionally alters a sound signal to produce sum/difference frequencies, which is the carve in audio-effect definition. Nearest kind per Law 11e: audio-effect sits between ring-modulator and signal-processing.

A chorus is a specific kind of audio effect: it intentionally alters a sound signal to thicken and enrich it through duplicated, modulated copies. A competent speaker would call a chorus 'an audio effect'. The nearest kind is audio-effect, not the broader modulation or signal-processing.

A vocoder (voice encoder) processes audio signals — it analyzes input and produces modified output through synthesis. It is a specific kind of audio processing device/effect. A competent audio engineer would classify a vocoder under audio effects. Files against the nearest kind — audio-effect.

Insert effect is a specific kind of audio effect: it is an effect unit placed in series within a signal chain, altering the signal's character. A competent engineer classifies insert effect as a form of audio effect. Nearest kind per Law 11e is audio-effect.

Pinned sense: the technique of running a signal through magnetic tape to add harmonic saturation, soft compression, and color — an intentional alteration producing a version distinguishable from the unprocessed source. That is the accepted carve of audio-effect (d6f97efd..., 'a signal processing technique or device that intentionally alters a sound signal to change its perceptual character, creating a version distinguishable from the unprocessed source') verbatim. audio-effect is the nearest live kind: the effect shelf where distortion, compressor, chorus, phaser, and reverb all sit (each with accepted INSTANCE_OF edges to it). Direction: specific (tape-saturation) -> general (audio-effect). Not a derivable leap — the audio-effect rung for tape-saturation did not exist; I struck the parallel filing against the broader audio-processing field for skipping this very rung (Law 11e), and this is the missing rung itself (Law 9, 11e).

Delay is a specific kind of audio effect: it intentionally alters a sound signal by returning discrete repeats of it (the classic echo repeats), matching the audio-effect shelf definition ('a signal processing technique or device that intentionally alters a sound signal to change its perceptual character'). The echo entry is a concept of the natural reflected-sound phenomenon, not an effect rung, so the nearest kind on the effect axis is the shelf itself — the same rung chorus, phaser, flanger, and comb-file all hold directly. Direction: specific -> general per Law 9.

Upward expansion is a specific kind of audio effect: it intentionally alters a sound signal by increasing gain below a threshold, changing perceptual character. A competent audio engineer would call upward expansion an audio effect. Nearest kind per Law 11e is audio-effect.

A pitch-shifter is a specific kind of audio-effect: it alters sound by changing its pitch while preserving duration. A competent audio engineer would call a pitch-shifter 'an audio effect.' Pin sense: the audio effect that shifts fundamental frequency without time alteration.

comb-filter is a specific audio effect that creates a series of regular peaks and notches in the frequency response (resembling a comb) through constructive and destructive interference of a signal with delayed copies of itself.
