Noise module provides the basic material to produce a whole spectrum
of sounds that do not have a defined pitch.
White noise can
be used to produce sounds such as wind, rain and surf.
`Pink' noise, which is white noise with the low frequency components
boosted, is used for sounds having a strong bass content, such as
the rumbling of thunder. The ASM-2 takes the fixed `pink' noise circuit
of the ASM-1 and adds two new controls that allow the user to increase
or decrease the Red (higher frequency components) and the Blue (lower
frequency components) of the `coloured' noise and provides a more
flexible noise source.
A further, third
stage, provides a random voltage output.
In addition to
modulating VCO signals, noise can be added to these signals to simulate
wind noise in organ pipes and woodwind instruments.
