Ear filter emulation
The ear filter emulator mimics the ear response to sound coming from different locations. This effect allows sound to appear as coming from behind.

Phase modulation
By changing the stereo separation of audio you can give phase modulated effects. Effect start around 14 seconds into the song (Space Ambience).
