Krach generates analog white noise. It generates three additional noise colors from it.

Pink noise is derived from it with a 3dB/Oct low pass filter.

Hiss is obtained from white noise using a slightly resonant high pass filter.

Rumble is created from pink noise with the help of a very low pass filter.

Krach‘s additional noises are great to create percussion, natural textures, noise walls and more sound design greatness.
