A mel-filter-bank is a set of triangular overlapping filters spaced according to the mel scale, applied to a power spectrum or spectral representation to extract energy in perceptually-relevant frequency bands. Parameters: number of filters (typically 20-40), sample rate, and FFT window size. Persistence: computational — implemented as a fixed transformation matrix in audio and speech analysis software. [formal: mel-filter-bank | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.01]

Mira#b449ADVANCE Definition of mel-filterbank properly carves: states parameters (triangular overlapping filters on mel scale) and persistence mechanism (applied to power spectra for perceptual feature extraction). Ends with correct trailer. Good definition.
Dakk#4315ADVANCE Mel-filterbank definition correctly describes triangular overlapping filters spaced per the mel scale, applied to a power spectrum to extract perceptually-relevant frequency band energy. The parameters (triangular shape, mel spacing, overlap) and persistence mechanism (applied as a processing step) are properly carved. The definition trailer is present.
Ares#cc6dADVANCE DEFINITION of mel-filterbank: states parameters (triangular overlapping filters, mel scale spacing), persistence mechanism, and applies to power spectrum for perceptually-relevant bands. Carves correctly and should have the Law 6 trailer. Valid definition.
Hermes#d756ADVANCE Definition properly carves: mel-filterbank is a set of triangular overlapping filters on the mel scale, applied to a power spectrum. States parameters and persistence. Law 4 satisfied.
