i was just (3 minutes ago...) trying to make some textures with pure data, with 4 oscillators and 1 LFO on each... and suddenly wanted to try binaural beats stuff...
well, everything was fine, until i try to get a under 4hz binaural beat !
suddenly i felt really strange feelings, being a bit drowsy...
a MUST TRY ! but a bit dangerous...

before i started doing electronic music, pre-astroid powerup in 2003, i did a bunch of stuff with detuning sine waves, blasting low ones through headphones. it brought back all kinds of short memory images from my youth-the wind in the trees, ice on a lake in november, etc.
very powerful stuff.
as i recall, it was none too precise, either. didn't really have to think about anything except for consonantly resonating my brain. simple consonance with some mild detuning of sine waves worked best. basic ratios separated by a couple of cents, turned up loud.

Sure. You start with a sine wave, at about 200hz. Now play a second sine wave, at about 218hz. When you have two waves that are detuned like this, you get an interference or beating pattern; instead of the pure sine tone it now goes woowoowoowoo, and the speed of the interference is the difference in original frequencies, 18hz in this case.
The next step is to take this signal, and pan one one the sine waves completely left, and one completely right. If you listen to only one side, you head a pure sine tone. But if you put on headphones, you will hear the interference pattern again. This is sorta odd, because the waves aren't actually interfering with each other in the air..the reason why you still hear it is not fully understood. Maybe your brain is exploited into perceiving it, or maybe that it resonates around inside your skull bones.
Anyway, the brain itself has its own frequency that changes when you change activity level, like from sleep to bored to fully alert. Normal consciousness is around 18hz. The theory behind the binaural frequencies for messing with your brain waves, hinges on a process called 'entrainment'. The general idea is that your brain would change operating frequency to resonate at the same frequency. And once achieved, you can slowly lower the resonating frequency, dragging the brains natural rythyms deeper. This may aid relaxation, induce trance states, whatever. The exact methods for doing all this vary quite a lot, and no one really knows if it fully works or not. Different people have many different ideas about the subject, so it's recommended to test for yourself to see if it works for you.
In my own case, I experimented with different carrier frequencies and descent rates, and played some ambient music over the top (which is often tuned to octaves of the carrier frequency). The interference patterns don't need to be very loud in the mix to get an effect. I found it relaxing, and after working on it I noticed that I could remember my dreams a lot more clearly. I got pretty spaced out during a few sessions, but nothing that wouldn't occur anyway with ambient music and a tired brain. Must try some longer or stronger sessions soon.
It's also interesting also to explore some of the ratios between brain frequencies and dance music bpm's.

thanks dach! i think i will try to create my own binaural music. nice primer!

idoser is bull - but binaural beats... well, YMMV... fun to play with, anyway. I used a SabGen sequence for the first track on my latest EP.

I just made a 4 channel piece based around binaural beats. 4 big Mackie monitors blasting bass -- it was wicked.

easy stuff... goood for changing brainwave states for use in meta-cognative programming and meditations.

yep binaural beats is cool stuff.
im sure there are some other insane things that can be done along this line that haven't been discovered yet, or ways to improve the effects.... part of the reason i am interested in making music is this.

yeah they're pretty awesome. I don't know how much you can really call it music, though, because binaural beats almost always sound the same except for a few minor variations. I guess it is, by the broad definition of music, but I see it more as a thing that people can do to help themselves relax or enter a certain state, and that's why there's so many programs that automatically make them for you, no need for a DAW ;)

It can be rich complex. I was running 16 oscillators (in pairs of 4 all modulating eachother [fm]).
"I don't know how much you can really call it music, though, because binaural beats almost always sound the same except for a few minor variations."
It's an effect, not a sound source. You could say that about heavy-compression or phasers. Sure, beating sine-waves are boring, but you needn't use sine-waves, and the beating need not be the entire mix.
