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.

```Rust

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

```

Types

-----

- [**Hz**](http://en.wikipedia.org/wiki/Hertz): "times per second".

- [**LetterOctave**](http://en.wikipedia.org/wiki/Letter_notation): musical letter notation.

- [**Mel**](http://en.wikipedia.org/wiki/Mel_scale): 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**](http://en.wikipedia.org/wiki/Semitone): MIDI semitone steps.
