Random Signal Generator

FUNCTION DESCRIPTION

The Random Signal Generator produces continuous bursts of random frequencies and waveshape from approximately 25 Hz to 20 kHz. Two types of energy distribution are provided: White noise and pink noise. The former distributes amplitude evenly throughout the indicated audio spectrum. The latter reduces the amplitude of each frequency increment proportionally to produce equal energy per octave. Pink noise, thus, sounds “lower” in pitch to the ear.

This Module is based on the original design from 1969
MUSICAL APPLICATION

Almost all acoustically generated sounds one hears, at all times, contain some amount of random noise. Most obvious are wind, surf and thunder. Some amount of unpitched sound is evident in just about every environment. Acoustic instruments produce varying amount of unpitched sound along with specific notes. Drums, Tam-Tam, blocks, gongs and various other percussion instruments are all unpitched instruments. White and pink noise provides the synthesist with a basic source for simulating these instruments, as well as a source for recreating “environments”.
As an audio source, the Random Signal Generator is most often used in connection with filters to create a desired frequency band or correct spectral sweeps. The Random Signal Generator also provides a source of control voltage for filters, oscillators, amplifiers and other voltage controlled modules, producing interesting random modifications.

As a source for the Envelope Follower, random triggers can be produced as well as slowly varying DC voltage contours (with slow response time). Noise is also useful as a control source for sample and hold circuits and random sequencer triggers.
