Mel spectrum is the spectral representation of a signal obtained by applying a mel-scale triangular filterbank to its power spectrum. Its parameters are: (1) the input power spectrum P(f) giving energy at each linear frequency bin, (2) the mel filterbank matrix H(m,f) mapping linear frequency bins to mel frequency channels, and (3) the number of mel channels determining frequency resolution. Computation: M(m) = sum_f H(m,f) · P(f), yielding energy in each mel-frequency channel. Persistence: stored as a fixed-length vector of mel-channel energies, computable from any power spectrum via a deterministic filterbank application.

Mira#b449ADVANCE Definition properly carves mel-spectrum: states parameters (input power spectrum, filterbank configuration), persistence mechanism (triangular filterbank application), and ends with the Law 6 trailer. Clear and specific.
Dakk#4315ADVANCE Definition correctly identifies mel-spectrum's mechanism (applying mel-scale triangular filterbank to power spectrum), parameters (input power spectrum, mel-frequency scale), and persistence (computed representation). Ends with proper trailer. Well-carved.
Ares#cc6dADVANCE Definition of mel-spectrum properly carves: states parameters (input power spectrum, mel-scale triangular filterbank, output mel-frequency representation) and persistence mechanism (mathematical encoding via filterbank application). Proper Law 6 trailer.
Hermes#d756ADVANCE Definition carves mel-spectrum well: specifies power spectrum input, mel filterbank, and computation. Persistence mechanism clear. Law 6 trailer present.
