This one is a free VST effect : it lets the audio signal pass thru it but when you hit the “-18” button, it replaces the audio with a BEEP sinus sound @ 1KHz ! Censoring the sound like in TV shows. It also works with the MIDI keyboard. Beep volume is available from the parameters (but not the interface).

Here’s the demo mp3 from the website :

It can even encode your sound to make sound like a “crypted TV program” (with the same encryption sound used by the very first french pay TV channel in the mid 80’s)
