Re: Speech Jammer ?
I remember back in the 70s hearing about a device that would do the same thing, it was used to play back to people claiming to be deaf.
If they couldn't talk while the device was on, they were hearing it.
Another thing about singing with delay, it is expected to hear the original signal, and then the delay.
Try doing it without the original signal.
When I do announcements from mix position, my speech slows down a lot, even from as little as 60' (20M) out because of the distraction.
