I am flirting with the idea of using 1/f noise (pink noise) as a control signal to various PD parameters. As some of you may know, the 1/f noise equation is commonly found in nature and various natural systems. It is characterized by a frequency power spectral density that decreases as the frequency increases, following a power-law distribution. It can be observed in many natural phenomena such as earthquakes, wind, even in the heartbeat. I am thinking-exploring ways (and the know how) to apply this characteristic to control various parameters within a self-generative future patch, from microscopic to macroscopic level (in either audio or control rates). Things like ADSR curves, to the density of pitched sounds within a time framed composition and everything in between.
As an example, 1/f noise can be observed in the sound of Rainfall The different raindrop sizes result in variations in sound frequencies and amplitudes. Suppose one drop of rain is synthesized, how could you apply the 1/f noise to generate a complete Rainfall realistically?
Any ideas and reference to other patches exploring this idea are welcome.
