Audacity Forum

You seem to believe it's as simple as recording some words, throwing a filter over the audio and ending up with a hypnotic message. If that could be done somehow, the advertising business would be all over it, wouldn't they?

EMI has done some research in the sixties that showed that you can influence people's subconscious feelings with modulated noise patterns. When coupled with single image ads in movie theaters, they could easily double popcorn sales. That particular research has been closed (you won't find anything about it on the net). It's also illegal in most countries.

Modulated noise (as in white noise, hiss) is easy enough to make. Audacity can do that. But you're on your own when it comes to find intensity, modulation frequency and so on. I'm not sure it's even a part of hypnosis.

Our hearing/brain filters out noise after a minute or so, if the modulation is constant and not too wild. But all of this doesn't work "in the wild". It works only in isolated, quiet environments like a movie theater. If there is "normal" background noise, it doesn't work at all.

I don't recall the numbers, if they were in the article I read so many years ago. It was around 1976 or so and it was an article in a fairly serious Dutch scientific magazine called "Natuur en techniek". That article got pulled a couple of months later. N&T doesn't seem to have an archive available that goes so far back.

So you can't simply create an effect. Even if you had the numbers.

You would need to recreate the experiment and the effect works best (or only?) if supported by images.
