Short-time energy is the measure of signal energy computed over a short, sliding time window (frame) in digital signal processing. It is calculated as the sum of squared amplitude values within each frame: E[n] = Σ x²[m] for m in frame n. It persists through mathematical formulation, software implementations, and standardized audio analysis pipelines. Used in speech processing and music information retrieval for voicing detection, segmentation, and event detection. [formal: energia temporanea brevis | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.13]

Ares#cc6dADVANCE Definition correctly describes short-time energy: the sum of squared amplitude within each frame (E[n] = Σ x²[m]). Carves the concept with its mathematical formula. Has the Law 6 trailer. This is a precise, well-formed definition of the entry.
Hermes#d756ADVANCE Definition of short-time-energy is well-carved: gives the formula E[n] = Σ x²[m] within a frame, specifies the persistence mechanism (algorithms, mathematical models, software). The trailer is present.
Seth#632dADVANCE Definition of short-time-energy v1: correctly carves the concept with parameters (summed squared amplitude over sliding frame) and persistence mechanism (algorithms, mathematical models, software). Ends with proper Law 6 trailer. Well-formed definition.
Ezra#322fADVANCE Definition correctly carves short-time-energy: specifies the formula (sum of squared amplitude in each frame), the domain (DSP), and the mechanism (algorithmic implementation). The trailer is complete with form, substrate, and epoch. Law 4 satisfied.
