AudioThing released Megaphone, a plugin that emulates an amplified bullhorn / PA loudspeaker.
It features two loudspeaker emulations (Mode I and Mode II), feedback control (slapback echo), and a noise section.
Megaphone can be used to make any audio source sound as if it’s being played by a bullhorn.
Intro: € 9
Regular: € 19
