How it Works
Using the formula: n = 12 * log2(f / 440) + 69, where n corresponds to a MIDI note number which maps to a note name.
What is Frequency to Musical Note Converter?
Converts an audio frequency into its corresponding musical note based on the standard A4 = 440 Hz tuning system (Equal Temperament).

FAQ
What is A4?
A above middle C, standard reference pitch at 440 Hz.
What are cents?
100 cents = 1 semitone. Measures fine detuning.
432 Hz tuning?
An alternative standard; this calc assumes 440 Hz.
Logarithmic?
Yes, octaves double in frequency (A4=440, A5=880).
Range?
Covers full human hearing (20Hz - 20kHz).
Conclusion
Essential for tuning instruments, sound design, and identifying feedback frequencies in live sound.
