Thanks to Google Cache, I was able to find my Megaupload link for my BWGen Binaural Beat I made.

So, basically, it starts you off at 8hz (so as not to hurt your ears) and then over 10 minutes takes you down slowly to 4hz... then keeps you there for 40 minutes. Afterwards it takes you back up to 8hz over another 10 minutes. Smiley
Lemme know if it downloads and works okay.
(( I had one that started at 15hz, but I found it too shocking to the system to start that high... it was very uncomfortable until it got below 10 hz. However, at 15hz... it really does wake you up! LoL ))
Whens the best time to try exit in 4hz?
For myself, generally I don't do "exits"... I do phasing.
"Exits" don't happen. So, through experience, I couldn't tell you... from research, I'd say try your exit technique whenever you're fully relaxed enough. :)
