FAQ

How does the megaphone effect work?

A megaphone effect is created by combining three processing steps: a band-pass filter that removes bass and high treble (limiting frequency range like a real speaker), dynamic compression that reduces loudness differences, and light distortion that adds the characteristic crunch of a cheap amplifier.

Can I use this on music, not just voice?

Yes. The effect works on any audio. Music will sound as if it is being broadcast through a PA system or over a walkie-talkie — useful for film sound design, music production intros, and creative effects.

What do the Drive, Tone and Echo controls do?

Drive controls the intensity of distortion and compression — higher values create a grittier, more aggressive sound. Tone adjusts the frequency range from a narrow telephone-like band to a wider stadium PA. Echo adds reverb and delay for a spacious, broadcast-like quality.
