I want to create silent subliminal am

Eldon Taylor says that silent subliminal fm tone doesnt work, so i want to create silent subliminal am, i wonder if somebody can help me, there is any script to make silent subliminal am?? thank you and sorry for my bad english. :blush:

Many people say that AM silent subliminals don’t work either.
Nevertheless, see this topic for how to create them: https://forum.audacityteam.org/t/silent-subliminals-solved/20100/1

If it’s not too complicated, could you explain what is the difference between “silent” subliminal AM and FM message?

Also what in practice means “silent”? What should then be non-silent?
