This is a classic theta brainwave entrainment sound made by two sine waves. The pitch shifts gently to produce some slow variation of the actual speed of the pulse. You can use it as a track and add voice (like relaxation or visualization), or just use as is to promote deep relaxation or trance. The pulses are about 8 hz (cycles per second).
25 of those squelching farting sounds you hear in psytrance. Each one is a little different. Made with ni massive, and a bit of processing in adobe audition.
A standard techno or trance bass loop introduction. I made this with the vst instrument called minimal. I forgot where it was from, just google it if you want to know i guess.
