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 human hearing range (20hz - 20khz)).
ScaledPerc (Scaled percentage of the human hearing range).
Step (MIDI semitone steps).

Add the following to your Cargo.toml.

[dependencies.pitch_calc]
git = "https://github.com/RustAudio/pitch_calc"

or

[dependencies]
pitch_calc = "X.X.X"

where "X.X.X" is the version you want (find the latest version in the Cargo.toml).

See the example for a simple demonstration.
