Venerable inter-app audio effect Frobulator reborn — at long last — as an AUv3 plugin. Use it in GarageBand, AUM or your favourite audio application. Add multiple instances in the same project. Drag your frobulation kicking and screaming into the 21st century. Frobulator is a spectral delay effect. It makes your noises a little bit stranger. Twiddle the knobs to find something you like, or don't and throw it away. No-one will hold it against you. Frobulator is free as in beer and free as in speech. Freer, probably, given the state of both those things these days. No ads, no in-app purchases, no subscriptions, no surveillance, no nag screens. If you happen to be one of the 6 people who asked for this, rejoice! If you aren't, now's your chance to discover what you've been missing all this time. Or not. I'm not the boss of you.
