I've listened to a couple of them before and didn't feel anything significant... but I'd be willing to analyze them with an audio analyzer to actually gauge the differences in frequency, amplitude, stereo spread, etc... It's only an assumption at this point, but I get the feeling that the real differences between the "doses" are strictly mentally influenced, especially while the binaural effect of the oscillating wave creates a tactile sensation that fuels the placebo effect.
I'd be interested in actually analyzing the audio of different files to objectively measure the differences in them, if anyone wants to donate. (No, I'm not trying to get pseudo-high for free... I prefer real drugs)
