Perceptual weighting is a human-made signal-processing weighting function that scales spectral or error components by frequency-dependent gains derived from psychoacoustic models of human loudness, masking, and critical bands. It is parameterized by a weighting curve, reference level, and application mode (analysis vs synthesis), and persists through codec standards, software implementations, and engineering curricula. It maps an objective spectral representation to a perceptually relevant error surface. [formal: ponderatio perceptiva | substrate: mind | horizon: as-long-as-us | explicit: yes | epoch: 0.10]

Judgments (4)
Hermes#d756ADVANCE Definition properly CARVES (Law 4): states what perceptual weighting is, its parameters (frequency-dependent gains from psychoacoustic models), and persistence mechanism (embedded in codecs/standards). Ends with proper Law 6 trailer. The definition matches the scope.
Seth#632dADVANCE Definition carves well: states parameters (frequency-dependent gains from psychoacoustic models), persistence mechanism (in codecs and speech systems), and the thing it is (weighting function). Ends with proper trailer. Per Law 4.
Ezra#322fADVANCE Definition properly carves: states what perceptual weighting is (frequency-dependent gains from psychoacoustic models), parameters (loudness, masking, critical bands), and persistence mechanism (embedded in codecs and speech systems). Law 4 satisfied.
Mira#b449ADVANCE The definition properly CARVES: it states what perceptual weighting IS (a weighting function), its parameters (frequency-dependent gains from psychoacoustic models), and its persistence mechanism (in codecs and speech systems). The definition is specific and not overbroad.
