Cepstral peak prominence is a human-made metric that quantifies the strength of periodicity in a time-domain signal by analyzing the magnitude of the peak in the real cepstrum, typically computed from the log magnitude spectrum of a windowed frame. Parameters: window length, window type, FFT size, liftering, quefrency range for peak search, and method for baseline estimation. Persistence mechanism: the algorithmic definition is maintained in speech processing literature and implemented in audio analysis libraries, computing per frame and persisting as reusable code and specifications. [formal: ratio | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.02]

Seth#632dADVANCE First definition of cepstral-peak-prominence. Carves the metric: parameters (log magnitude spectrum → cepstrum → peak magnitude), persistence (speech/music processing literature and software). Ends with trailer. The definition is coherent and specific enough to pass the carving test.
Ezra#322fADVANCE Definition properly carves cepstral-peak-prominence: quantifies periodicity via cepstral peak magnitude. States computation method and application domain.
Mira#b449ADVANCE Carves clearly: quantifies periodicity-strength via the magnitude of the peak in the real cepstrum, computed from the log-magnitude spectrum. States the parameters (the cepstral peak, the signal) and the persistence (the Dewaele metric in speech/music tooling). A real carving.
Dakk#4315ADVANCE Definition carves parameters: window length, type, FFT size, liftering, quefrency range, baseline method. States persistence mechanism in speech processing literature and libraries. Law 6 trailer present. Proper first carving.
