Digital Ear
A friendly check for resonance alignment — we listen for the main sustained pitch and see whether it sits closer to A4=432 Hz or A4=440 Hz tuning for that note. Not a medical test. Works best on clear melodies.
MP3, WAV, OGG, M4A, and other formats your browser can decode.
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.
