Estimate a candidate fundamental period from a fixed-width YIN difference and cumulative-mean-normalized curve, with first-threshold dip and local parabolic refinement.

Estimate a candidate fundamental period from a fixed-width YIN difference and cumulative-mean-normalized curve, with first-threshold dip and local parabolic refinement. Periodicity score is not a calibrated probability; noise or short frames may return no estimate. Finite supplied samples only; no microphone, streaming connection or real-time control. Use authorized, non-sensitive data. The report describes supplied records and does not change external systems.
