THIS FILE IS JUST TONES, NO WORDS. This is the audio illusion of the ever-decreasing tone with a simple 2Hz beat on it. I have been experimenting with this effect for some years but this is the first version I have been satisfied with. It may send you very, very deep. Or it may give you vertigo. Or both. Let me know! If you want to publish a file with this file as part of it then please do, but please give credit! My beats have been known to induce trance on their own so USE WITH CAUTION. This is a mono file, 44 minutes, 320kbps, 100Mb.
