A library for musical pitch conversions!

pitch_calc provides functions and methods for converting between frequency, midi-step and letter-octave.

It looks like this.

assert!(Hz(440.0).letter_octave() == (A, 4))

Types

  • Hz: "times per second".
  • LetterOctave: musical letter notation.
  • Mel: a perceptual scale of pitches judged by listeners to be equal in distance from one another.
  • Perc: Percentage of the average human hearing range (20hz - 20khz).
  • ScaledPerc: Scaled percentage of the human hearing range.
  • Step: MIDI semitone steps.
