Tool to generate audio frequencies.

## Synopsis

```swift

let notes = HarmonyKit.tune(

    configuration: .init(

        temperament: .equal,

        pitch: 442,

        transpositionTone: .C,

        octaveRange: 1..<2

    )

)

notes.forEach { print($0) }

// =>

// tone: E, octave: 1, frequency: 41.390736

// tone: F, octave: 1, frequency: 43.851955

// tone: B♭, octave: 1, frequency: 58.53534

// tone: G♭, octave: 1, frequency: 46.459526

// tone: A♭, octave: 1, frequency: 52.149055

// tone: E♭, octave: 1, frequency: 39.06765

// tone: C, octave: 1, frequency: 32.851845

// tone: B, octave: 1, frequency: 62.016026

// tone: D, octave: 1, frequency: 36.87495

// tone: G, octave: 1, frequency: 49.222153

// tone: A, octave: 1, frequency: 55.25

// tone: D♭, octave: 1, frequency: 34.80532

```

You can also specify pure temperament:

```swift

let pureMajorNotes = HarmonyKit.tune(

    configuration: .init(

        temperament: .pure(.major, rootTone: .C),

        pitch: 442,

        transpositionTone: .C,

        octaveRange: 1..<2

    )

)

let pureMinorNotes = HarmonyKit.tune(

    configuration: .init(

        temperament: .pure(.minor, rootTone: .C),

        pitch: 442,

        transpositionTone: .C,

        octaveRange: 1..<2

    )

)

```
