HarmonyKit

CI Status Xcode 10.0+ iOS 11.0+ Swift 4.2

Tool to generate audio frequencies.

Synopsis

First you need to define a tuning setting

let setting = HarmonyKit.Setting(
    pitch: 442,
    scaleType: .equal,
    rootTone: .C,
    transpositionTone: .C,
    octaveRange: 1..<2
)

and then

let harmonies = HarmonyKit.tune(setting: setting)
let sortedHarmonies = harmonies.sorted()
sortedHarmonies.forEach { print($0) }
// =>
// tone: A, octave: 1, frequency: 55.25
// tone: Bb, octave: 1, frequency: 58.5353
// tone: B, octave: 1, frequency: 62.016
// tone: C, octave: 1, frequency: 32.8518
// tone: Db, octave: 1, frequency: 34.8053
// tone: D, octave: 1, frequency: 36.875
// tone: Eb, octave: 1, frequency: 39.0676
// tone: E, octave: 1, frequency: 41.3907
// tone: F, octave: 1, frequency: 43.852
// tone: Gb, octave: 1, frequency: 46.4595
// tone: G, octave: 1, frequency: 49.2222
// tone: Ab, octave: 1, frequency: 52.1491

If you specify .pureMajor for scaleType:

sortedHarmonies.forEach { print($0) }
// =>
// tone: A, octave: 1, frequency: 54.7544
// tone: Bb, octave: 1, frequency: 59.1335
// tone: B, octave: 1, frequency: 61.5983
// tone: C, octave: 1, frequency: 32.8518
// tone: Db, octave: 1, frequency: 34.2212
// tone: D, octave: 1, frequency: 36.9581
// tone: Eb, octave: 1, frequency: 39.4213
// tone: E, octave: 1, frequency: 41.0645
// tone: F, octave: 1, frequency: 43.8013
// tone: Gb, octave: 1, frequency: 45.6271
// tone: G, octave: 1, frequency: 49.2791
// tone: Ab, octave: 1, frequency: 51.3302

.pureMinor:

sortedHarmonies.forEach { print($0) }
// =>
// tone: A, octave: 1, frequency: 54.7544
// tone: Bb, octave: 1, frequency: 59.1335
// tone: B, octave: 1, frequency: 61.5983
// tone: C, octave: 1, frequency: 32.8518
// tone: Db, octave: 1, frequency: 35.4792
// tone: D, octave: 1, frequency: 36.9581
// tone: Eb, octave: 1, frequency: 39.4213
// tone: E, octave: 1, frequency: 41.0645
// tone: F, octave: 1, frequency: 43.8013
// tone: Gb, octave: 1, frequency: 47.3071
// tone: G, octave: 1, frequency: 49.2791
// tone: Ab, octave: 1, frequency: 52.5634
