NUCLEAR CRANIUM is a free multi-band distortion and sound shaping tool designed to inspire creativity in experimental music production. It processes audio by dividing the input into four distinct frequency bands: high, mid, low, and an additional layer labeled 'else.' This allows for detailed manipulation of different parts of the sound spectrum, enabling unique and complex sonic transformations.

Each frequency band features its own set of effects, including pitch shifting, bit crushing, waveshaping, crunch, psychodelay, and autopan, with independent wet/dry controls and volume sliders. Users can toggle each band on or off to optimize CPU usage, providing flexibility in sound design and system performance. This approach allows for precise and layered distortion effects that can radically alter the character of any audio source.

NUCLEAR CRANIUM also offers fully customizable LFOs on nearly every parameter, enabling dynamic modulation and evolving sound textures. The user interface is designed with comprehensive tooltips, making it accessible for both beginners and experienced producers seeking to explore new sonic territories. Overall, NUCLEAR CRANIUM delivers a powerful environment for crafting distinctive and experimental audio effects.
