You can fully adjust the range that the signal can vary between (randomly), as well as the distance or duration of one random value until it changes to another, but it will always be smooth regardless of this setting, this just tells it how slow it should be with changes. Now, do the moving average on this whole thing (with the period or length set to the distance between points) - and you got the smooth random signal… Basically, think of it as generating a specific amount of random points for a given time frame, and drawing lines between these points: that’s your linear interpolation. The smoothing method used is a quadratic function, based on the moving average of linear-interpolated randomly-generated points. It basically generates a “control” signal as an audio signal (or random LFO), so it is definitely not meant to be listened to (directly)! The signal generated is random, however, it will be smooth between the random points generated. Random Smooth Signal is a JSFX script that generates a continuous random smooth signal. Random Smooth Signal is a free oscillator VST plugin for Reajs and Reaper developed by octarone.
