Again, we don't live in a fairyland, we live in reality. A gun is real, your magic is not. If you had a gun that fired based on a sound, the fact that a sound is used does not matter. It is not "speech". Noise is not protected speech.

Likewise, if you had the magical ability to kill a random person with your magical sounds, you are not practicing "speech", you are using a magical technique in your make believe land to kill random people.
