Random Noise

Faceplate Faceplate

Sources of white and coloured random noise based on Ray Wilson's Noise Cornucopia.

  • Module size: 4HP (20mm)
  • Power: 10mA (+12V); 2mA (-12V)

Project Source

The project files, including schematic and layout, are available on github.

Features

Random noise is a signal source module with multiple line-level audio outputs:

  • White noise between 10Hz and 10kHz+ with a 10Vpp output
  • Pink noise (10dB/dec fractional LPF) with 60Hz corner
  • Blue noise (10dB/dec fractional HPF) with 10kHz corner
  • Grains output with threshold control

The grains output consists of random positive and negative impulses, creating a static sound.
