Poltergeist

Poltergeist is a unique and truly original effect pushing the boundaries of audio processing. In multiple stages, it generates intricate, fractal-like phasing patterns on the audio input - a vast soundscape capable of producing:

1) bold new sounds, 2) subtle textural depth and beauty, 3) thrilling reimaginations of traditional analog effects,

4) and everything in-between. The many possible uses of Poltergeist are largely unexplored - tread bravely.
