Found out how it works (quoted from wikipedia):
As a conceptual example of an ascending Shepard scale, the first tone could be an almost inaudible C(4) (middle C) and a loud C(5) (an octave higher). The next would be a slightly louder C#(4) and a slightly quieter C#(5); the next would be a still louder D(4) and a still quieter D(5). The two frequencies would be equally loud at the middle of the octave (F#), and the eleventh tone would be a loud B(4) and an almost inaudible B(5) with the addition of an almost inaudible B(3). The twelfth tone would then be the same as the first, and the cycle could continue indefinitely.

TRANSLATION:
The bottom notes start out really quiet, and get louder as they go upwards, while the top notes start out loudest, and progressively lose volume as they descend. The process repeats, resulting in the constantly falling feel.

*descend=ascend

Yeah they faded it in too hard. When done well the transition can be almost imperceptible.

And the Battle Against Lord ExDeath (Fierce Battle) from Final Fantasy 5

also, this is probably what hell sounds like.

It's the place between Hell and the Land of Myths.

5 stars for Baleen

More for Baleen.

You have introduced me to the most unsettling sound I have ever heard. It's like something out of Lovecraft.

Baleen just proved e-Dosing is real.
