Metal Demon Usage Notes

These notes will help you get the most out of Metal Demon, the death metal vocal effect that defiles even the purest voice. DirectX and VST versions are available.

Metal Demon works best on solo vocal tracks, before any echo or reverb has been applied.

Controls

The Balls knob controls how butch the voice sounds, ranging from almost natural to diabolically deep. Metal Demon always transposes the vocal one octave down, the Balls knob changes the vocal characteristics or formants.

The Throat knob controls how hoarse the demon's larynx is, from relatively clear to totally tortured.

The Muffling knob adds further control to how clear the vocal sound is. The minimum setting is quite clear but may have some edgy glitches, higher settings will reduce the glitches but also the clarity.

A word about FFT-based vocal format shifting

Metal Demon works by dividing a small "chunk" of sound into a large number of frequency-based components. This is done using a method called "fast fourier transform", or FFT for short. After the sound is divided, some of the components are shifted, changing their frequency.
