What does it sound like?

How is it different from Radio?
Megaphone is harsher and distorted for a shouting tone; Radio stays cleaner.
What lines work best?
Short, punchy call-outs and commands land hardest; keep the source clean so the grit sits on top of clear words.

What the megaphone effect does
It squeezes the voice into a punchy midrange, adds a touch of distortion and a short slap echo, so speech booms out like a bullhorn or PA system. The result is loud, urgent and hard to ignore.
Megaphone vs radio
Both thin out the sound, but megaphone is harsher and more distorted for a shouting, in-your-face tone, while Radio stays cleaner. Reach for megaphone for protests, coaches and announcements.
Tips
- Short, punchy phrases and call-outs land best.
