This is a smoothly rising shepard tone that i created using adobe audition 3's tone generator. I generated the tone as sine waves in 7 different octaves and mixed the results together. The period of repetition is 10 seconds. (this is a second version in which i removed the phase variance, making the sound monophonic for all practical purposes).

A highly-modified shepard tone. Reversed, inverted, reverbed, added bass with lowered treble, and to top it all off a highly resonant wah-wah sound effect. All made in audacity.
