Noise

Audio modules - Noise

There are 4 different kinds of noise that you can choose from:

  • White Noise
    Random signal with a flat power spectral density.
  • Pink Noise
    Noise with the volume of the higher frequencies gradually reduced by 3db/octave.

    • In both the pink noise and white noise setting, Zebra2 has a 6dB low pass and a 6db high pass filter to adjust the sound of the noise.

  • Digital Noise
  • Crackles

The noise modules can be used either mono or stereo. In stereo mode the width controls the spread of the two channels. Use pan to set the stereo position of the modules output and volume to adjust its level. Both pan and volume can be modulated directly from within the module using the usual knob/popup menu (see “Knobs” in “User Interface”).

There are two filters built into the noise module. In white noise and pink noise mode Filter 1 is a lowpass and Filter 2 a highpass in the other modes Filter 1 controls the pitch and Filter 2 controls the amount of noise. Both filters have direct modulators using the usual knob/popup menu(see “Knobs” in “User Interface”).
