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

TRANSPARENT BY DESIGN
Ten measurements.
One clear methodology.
PhoniPy maps detected fundamental frequencies to individual musical notes and measures the duration and harmonic purity of stable intervals.
Read the technical specificationFind the stable intervals.
Eight consecutive same-note frames qualify by default, corresponding to a nominal 138 ms hold.
Describe the recording.
Ten defined measures describe timing, stability, fragmentation, harmonic energy, and reference-note offset.
