More about this voice

Why it sounds big, not slowed down

A record played too slow sounds sluggish because everything moves down together. The monster preset moves the size of the voice (Tone -6) further than its note (Pitch -8), so it sounds like a huge throat speaking at normal speed. That's what makes it a creature rather than a broken tape.

The growl is distortion at 0.5, mixed in at 60%, so your words stay under it. A bass boost below 140 Hz adds weight, and the treble above 7 kHz is cut so the distortion doesn't fizz.

Growl tips

Roar from your chest, not your throat. The effect adds the grit, so you don't have to strain.
Keep a hand's width from the mic. Up close, plosives turn into thumps.
If your mic clips on roars, turn its input level down in your system settings rather than the effect.
