The loops contain brainwaves. The range is more or less from 3 cycles per second (Hz) to 13 Hz. It depends on the loop. You should use headphones, because the spatial sound between channels is the most important to the proper functioning. The loops are highly recommended for chronic addicted masturbators. They give an excellent effect when you listen to them in the background to your favorite porn.

Selected Mindfuck Loops Vol.2 - Loop7

Each compilation (Vol.1,2,3) contains brainwaves  - the spatial phase rotations between left and right channel. For  example: one cycle per second = 1 Hz. I used the range between 3 - 15  Hz, each loop is encoded separately. 
So, it is very important to understand - you have to use headphones for these loops to put yourself into bate trance - and the best effect is when music is just a background for your favorite porn. Enjoy your self hypnotic trance!
