tool.musical-intervals-hz Calculator
Converts between musical note names, MIDI numbers, and frequencies in Hz, displaying all 12 semitones relative to a reference pitch. Useful for synthesizer tuning, acoustic analysis, and pitch-matching between instruments in different tuning standards.
Inputs
Base Frequency Hz
Cycles per second (Hz). Audible sound: 20 Hz – 20 kHz. Make sure units match what the formula expects.
Semitones Above
Reference formula or conversion factor shown for context.
Results
frequency (Hz)
Sample size or count used in the calculation.
note name
Supplementary information explaining an assumption, caveat, or important context for interpreting the result.
octave change
Sample size or count used in the calculation.
f = f₀ × 2^(n/12)
Sample size or count used in the calculation.
A4=440Hz → A5
