McDSP FutzBox is a distortion and noise generator plug-in for creating low-fidelity versions of audio signals.

Typical post productions require distorted, or "futzed" versions of dialog and other tracks. Simulations of radios, cell phones and televisions are now available in a single software product. These simulations, called SIMs (Synthetic Impulse Models) provide accurate modeling in an extremely optimized format, allowing FutzBox to use less DSP power than conventional convolution based products. Furthermore, SIMs can be scaled in real-time and changed on the fly.

In addition to the SIM library of sounds, FutzBox also includes filtering and EQ, distortion, a noise generator and gating to complete the sonic destruction required. Original and distorted audio can be mixed in real-time to accommodate scene changes or other automation requirements.
