Is there  subliminal audio in this. I hear something  but can't make it out. It sounds a little bit like random rhythms made by someone swiping their fingernails on some taught fabric but muffled and very low volume. Its distracting me from the low frequencys.
The low frequencies sounds like a big truck idling.
hehe, nope :)
If you have the know-how, check out the audio track in a spectrum analyzer. Just 2 pure tones. It's not uncommon to hallucinate while falling asleep.
