Obtén la frecuencia exacta en Hz de cualquier nota musical en todas las octavas, con referencia A4 personalizada (440, 432, 442 Hz) y soporte de desafinación en cents.
| Nota | Frecuencia (Hz) | MIDI | Período (ms) |
|---|
Temperamento igual: f = A4 × 2^((midi − 69) / 12). Cada semitono equivale a 2^(1/12) ≈ 1.0595×. Los cents son 1/100 de un semitono: un desplazamiento de +c cents multiplica por 2^(c/1200).
La nota MIDI 69 = A4. C4 (do central) es MIDI 60.
