Method
A basic chart was used with a scale from 0-100 for simplicity.
Setting the value to will play the graph curves, what we want is discrete notes, so we set this value to .AXDataSeriesDescriptorisContinuoustruefalse
Using Piano Key Detector app, the discrete sounds were mapped to music notes across intervals of .5
// .init(time: 0, value: 0), // C5
// .init(time: 1, value: 5), // D5
// .init(time: 2, value: 10), // D5
// .init(time: 3, value: 15), // D#5
// .init(time: 4, value: 20), // E5
// .init(time: 5, value: 25), // E5
// .init(time: 6, value: 30), // F#5
// .init(time: 7, value: 35), // F#5
// .init(time: 8, value: 40), // G#5
// .init(time: 9, value: 45), // G#5
// .init(time: 10, value: 50), // A#5
// .init(time: 12, value: 55), // A#5
// .init(time: 13, value: 60), // B5
// .init(time: 14, value: 65), // C6
// .init(time: 15, value: 70), // C#6
// .init(time: 16, value: 75), // D6
// .init(time: 17, value: 80), // D#6
// .init(time: 18, value: 85), // E6
// .init(time: 19, value: 90), // F6
// .init(time: 20, value: 95), // F#6
// .init(time: 21, value: 100) // G6
Once the notes were identified, a simple version of Clair de Lune was found, https://www.youtube.com/watch?v=ra08MiW8jLw
This was manually mapped to the music notes identified above, with pauses in the song where appropriate.
