Telinga Digital
Pelacakan nada (YIN): mencari not yang paling lama berkelanjutan, lalu membandingkan frekuensi terukur lebih dekat ke temperamen sama La4=432 Hz atau La4=440 Hz untuk not yang sama. Bukan diagnosis medis. Akor dan campuran padat membingungkan satu nada.

Exploration only. This is not proof the entire track was remastered from A440 — only how one predominant sustained pitch compares on this pass. Not a lab-grade measurement. When shown, overall tempo uses a browser-side rhythm model (Essentia) on the uploaded or linked file — not the live microphone. Weird meters, heavy rubato, very short clips, or sparse material can still mislead any tempo estimator.
