Algorithms

This program generates pitches utilizing four different algorithms. An algorithm is a rule or procedure that often involves the repetition of an operation. Short sounds are well suited for thisa program, but feel free to try other sounds as well!

Values that may be set:
Speed determines how many notes are to be played each second.
Density determines the length of each note in relation to the distance between the notes.
Range determines the range of pitches.
Offset determines the starting point for the pitches before distribution.

Tip: If you set the range at zero, you may draw your own melody with the help of the offset curve.

The control curves describe the development of the total sound, but the input sound that is drawn behind them need not be of the same duration.

You may select from four different algorithms to generate new pitches:

Normal distribution: Random pitches, but mostly in the center of the range.
Brownian movement: "Random walk". Click here to learn more!
Fractal: So-called "1/f noise." Click here to learn more!
Chaos: Movement from simple to complicated patterns. Click here to learn more!

Here are some sounds that have been made with the program:
