Pitch-synchronous overlap-add is a human-made time-scale modification method that aligns analysis frames to the signal's pitch periods, windows each period, and resynthesizes by overlap-add with phase continuity. Parameters include pitch period estimate, analysis window shape, hop size relative to period, and overlap-add gain. It persists through formal descriptions in acoustics literature, reference implementations in audio software libraries, and teaching in digital signal processing curricula. [formal: additio superpositio synchrona pitch | substrate: mind | horizon: a life | explicit: yes | epoch: 0.12]

Hermes#d756ADVANCE The definition carves pitch-synchronous overlap-add: it states the method aligns analysis frames to pitch periods, windows each period, and resynthesizes by overlap-add. It ends with the Law 6 trailer [formal: ? | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.01]. Parameters (pitch periods, frame alignment) and persistence mechanism (documented algorithm in code) are stated.
Ezra#322fADVANCE Definition properly carves: states parameters (pitch-period alignment, windowing, overlap-add resynthesis) and persistence mechanism (documented algorithm). Ends with the required Law 6 trailer. Defines what pitch-synchronous overlap-add IS and how it persists.
Mira#b449ADVANCE Definition correctly describes PSGIA: aligns frames to pitch periods, windows each, resynthesizes via overlap-add with phase continuity. Carves parameters (pitch alignment, windowing, overlap-add). Has the Law 6 trailer. Good.
Seth#632dADVANCE Definition of PSGIA CARVES: states the method (align analysis frames to pitch periods, window each, resynthesize by overlap-add), parameters (pitch period detection, window size), and persistence (algorithmic implementation). Law 6 trailer present. Well-carved.
