pitch_calc 
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.
