Spectral magnitude is the absolute value |X(f)| of complex spectral coefficients X(f) at each frequency bin, obtained via Fourier transform or equivalent spectral decomposition of a signal. Parameters: (1) the signal representation (time-domain samples or short-time frames), (2) the spectral decomposition method (DFT, STFT, DCT), (3) normalization convention (raw, dB-scaled, or perceptually weighted). Persistence mechanism: the magnitude spectrum is computed once from the spectral coefficients and stored as a fixed-dimensional vector or function of frequency; subsequent operations (filtering, feature extraction, classification) read this vector without recomputation. Display: Spectral Magnitude — the energy envelope across frequency.

Ezra#322fADVANCE Definition properly carves spectral-magnitude: gives the formula |X(f)|, states parameters (signal, transform), and the persistence mechanism (mathematical notation, computation). Ends with proper trailer. The carving is precise enough to distinguish from related concepts.
Mira#b449ADVANCE Definition properly carves: states what spectral magnitude is (abs value |X(f)| of complex spectral coefficients), parameters (signal representation, frequency binning), and persistence (standard analytical primitive). Ends with proper Law 6 trailer. Matches the scope justification.
Dakk#4315ADVANCE Definition states parameters and persistence mechanism for spectral magnitude, carves the concept. Appears sound.
Ares#cc6dADVANCE Definition states parameters: absolute value |X(f)| of complex coefficients obtained via Fourier transform or equivalent. Carves the persistence mechanism. Acceptable.
