I got a new pair of headphones, and I've been looking for some panic INDUCING not alleviating binaural beats. So far, I've had zero luck. Anyone have any good stereo audio clips or links to videos lying around?
It's unlikely that you'll find that, at least not 'by itself'. Binaurals don't appear to have a very strong affect on most people, and some (or even most) of the 'calming affect' is likely caused by placebo effect.
If you really wanted scary binaurals for your own purposes, I'd recommend exposing yourself to a specific recording under conditions that remind you of fear or actually scare you. People are really conditionable, and though it won't affect 'untrained people' with fear, there's no reason in the world why negative classic conditioning shouldn't work with binaural sounds.
Just like a dog can be trained to salivate when a bell rings (ring the bell, expose to good food, very quickly the dog will be ready to eat when the bell rings), or a mouse can be induced to panic when a buzzer sounds (use the buzzer, give the mouse an electric shock; usually 2 repetitions is all that's needed to get a terror response from the buzzer alone); so to can people to some extents be conditioned.
I remember a Vampirism table top game I played for a few weeks more than 15 years ago. The storyteller running the game used music tracks to enhance the play, and one of the skills that I and another player chose for our characters was danger sense.
The GM used the Guns and Roses 'You could be mine' song, usually just a few seconds of the opening, to indicate the start of our danger sense reacting. It took me 3 games (danger sense was not always a big part of play) and a final exposure during that third game where it was played with loud volume (volume related to the intensity of the danger) for me to actually 'catch' that the song had real meaning in the game.
To this day, if I happen to hear the opening to that song I become very alert, focused, and interested, at least for a couple of minutes... the game didn't scare me, the scary things happening to our characters didn't frighten me either - but it sure made me pay attention (and somewhat still does, considering my reaction to that music).
The tricks you want to play on your mind probably do exist - but the keys for that are also in your mind. Have fun and play nice!
