I assume from the Brain Wave Generator website that one could put together a binaural beat track with a progressively lower carrier frequency. Am I correct in assuming that this can be done with a simple rain track, (as used with Awakened Minds) as opposed to the musical overlays that feel like New Age Geritol for the brain?

Btw, I admit to having my own crappy tastes in music; I just don't want them for entrainment or meditation purposes. Just the rain please. Or maybe chickens . . . or a field of geese . . . hey, even a backhoe would do.
