ANALYSIS COMPLETE

Pitch movement and the intervals that meet your stability settings.

Detected series / total acoustic energy

Blue markers show interval onsets; red markers show offsets. Times follow the analysis hop.

A dash means no qualifying observations were available. These measurements describe the recording; they are not a clinical diagnosis.

TRANSPARENT BY DESIGN

PhoniPy maps detected fundamental frequencies to individual musical notes and measures the duration and harmonic purity of stable intervals.

01 / DETECT

Short overlapping windows identify a periodic pitch candidate and measure its harmonic-series energy.

02 / CONFIRM

Eight consecutive same-note frames qualify by default, corresponding to a nominal 138 ms hold.

03 / MEASURE

Ten defined measures describe timing, stability, fragmentation, harmonic energy, and reference-note offset.
