Ganzfeld effect

Without looking up what Ganzfeld effect is or reading the comments, try this video: http://www.youtube.com/watch?v=8z7cE-M0ZaI

Really intense... Damn. I cannot get past 2 mins before it becomes too overpowering.

This is one of the I-Doser binaural beats. I have all of them. Here's the SBaGen source:

Code:

-SE

h5:   pink/10 100+.5/90
h1:   pink/10 100+1/90
h2:   pink/10 200+2/90
h4:   pink/0 400+4/300
alloff:      -

NOW       h5
+00:05:00 h5 ->
+00:06:00 h1
+00:13:00 h1 ->
+00:14:00 h2
+00:22:00 h2 ->
+00:23:00 h4
+00:28:00 h4 ->
+00:30:00 alloff

Here's a video I made about the effect:

Are there any puredata patches?

I don't know anything about that.

The concept is pretty simple, so you should be able to deal with binaural beats in any environment.

Code:

pink/10 100+.5/90

This means:
- Play pink noise at volume 10.
- Play a sine wave at 100 Hz at volume 90 in one channel.
- Play a sine wave at 100.5 Hz at volume 90 in the other channel.

100 Hz is the carrier frequency. 0.5 Hz is the entrainment frequency.

In the SBaGen timings, "->" slides frequencies to the target so that there isn't an abrupt change.

Strange. It worked last night; first time I was seeing stars then faces and I instantly stopped because it freaked me out. Second time some big ancient tunnels. But now this morning nothing's happening :/

Guess you have to be tired and relaxed.

Edit: OK, well I got some nice visuals and cool imagery, but nothing as intense as last night...

You get acclimated to these quickly. Try this, one of my favorite I-Doser ones:

It's basically just several different euphoria frequencies. (It's not designed to make your head explode like Gates of Hades or Hand of God.)
