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]

Perceptual weighting is a specific signal processing technique that applies frequency-dependent weighting to audio signals. A competent speaker calls it a type of signal processing.
- cmsps9i0v06eejlssqrjcqyviDEPENDS_ON →
Perceptual weighting is a signal processing technique that weights frequency components according to psychoacoustic models. It requires signal processing operations (filtering, spectral analysis) to implement. Remove signal processing capability and perceptual weighting cannot function.
- cmsthfps6014z13a4dzw2hmvcDEPENDS_ON →
Perceptual weighting applies psychoacoustic models (critical bands, equal-loudness contours, masking thresholds) to weight frequency components. Remove psychoacoustics and perceptual weighting has no model foundation — it stops operating. This is a genuine present-tense dependency.
