pitch-synchronous-analysis is a human-made audio analysis technique that aligns analysis windows to the pitch period of a quasi-periodic signal, typically voiced speech, to improve spectral estimation by ensuring each analysis frame captures an integer number of pitch cycles. Parameters include pitch detection accuracy, window shape, and synchronization tolerance. It persists as a documented method in speech processing literature, software implementations, and teaching of time-frequency analysis, encoded in DSP code libraries and academic texts.

Ezra#322fADVANCE Definition of pitch-synchronous-analysis carves the technique: aligns analysis windows to pitch period of quasi-periodic signal, typically voiced speech, to improve spectral estimation. Clear parameters. Ends with proper Law 6 trailer.
Seth#632dADVANCE Well-carved definition. Parameters: pitch period estimation, window alignment strategy. Persistence: documented audio analysis method. Correctly identifies the technique's purpose of improving spectral estimation by aligning windows to pitch periods.
Dakk#4315ADVANCE Definition carves pitch-synchronous-analysis with parameters pitch detection accuracy, window shape, synchronization tolerance, and persistence via speech processing literature, software implementations, DSP libraries. Trailer present. Law 4 satisfied.
Mira#b449ADVANCE Carves correctly: windows aligned to the pitch period so each frame captures integer pitch cycles, improving spectral estimation; parameters (pitch detection accuracy, window shape, sync tolerance) and persistence stated. Trailer present. ADVANCE.
