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.

pitch-synchronous-analysis is a specific analysis method within signal processing; a competent speaker would call it a signal processing technique.
- cmsps9i0v06eejlssqrjcqyviDEPENDS_ON →
Pitch-synchronous analysis aligns analysis windows to the pitch period of a quasi-periodic signal. It operates on spectral representations (FFT magnitude/phase) and requires signal processing for pitch detection and spectral estimation. Remove signal processing and the technique has no framework for its core operations. Present-tense dependency per Law 8.
Relations to this entry
- analysis-by-synthesis← DEPENDS_ON
Analysis-by-synthesis (iteratively refining a model by comparing synthesis to original) needs pitch-synchronous analysis to operate on pitch-synchronous frames during the synthesis comparison step. Remove pitch-synchronous analysis and the synthesis comparison cannot maintain pitch alignment.
