I made this as a strange wake-up alarm.
I was wondering at what point I will wake-up? What frequency will break my dream and bring me back on earth?

Created using Audacity.

    I'm surprised with your rich feedback! Thanks! :)

    @ AlienXXX :

    I believe the first thing I heard when I woke up was between 200-400 Hz, my speakers are boosting around 400 Hz, so maybe that's the reason. I'll try it again today (it's 4 AM now, I was on a party).

    Too bad my guitar amp makes fuzzy noises (I can't sleep when it's on), it reflects frequencies below 150 Hz much better.

    I actually wanted to make this a gentle but reliable alarm. The glissando is really slow, but noticeable. The frequency range is wide.

    I also wanted it to start as unaudible - instead of making a fade-in, I made it begin at 10 Hz - 10 Hz below human hearing and around 30 Hz below common speaker's range.

    @ AlienXXX - I was surprised how beautiful these colors are, I didn't think of this :D

    There are loud peaks at 3 and 8KHz ... http://en.wikipedia.org/wiki/File:Perceived_Human_Hearing.svg

    I also want to know how the experiment worked.
    But I suspect unfa uploaded this sound just to see the pretty colours. :p
