Aire freshener is a software relaxation tool much like a sound spa. It works fine on my XP Sp-1 install. Dunno about other operating systems. If you have a colicky baby at home or a grandpa who watches television without his hearing aids, then this software was what the doctor injected into you with a 12-inch long syringe.
Aire Freshener is the best music to sleep by. Aire Freshener has real recorded audio that loops seamlessly. It has many different soothing environments to choose from, waves at beaches to Crackling Fireplaces to Wind Chimes. There are just too many options to mention, so here's a screenshot.
Apart from Environmental sounds, it can also have Air Chimes, which let you decide the right kind of ambience, and an inspirational quote for the day, which gave me this
"One person's bullshit is another person's chicken soup for the soul."
If you have the bandwidth, then you must try this software out. I just leave it on all day and it circulates the room with soothing sounds. There's a direct download link from the authors Web site, please leech it off while you can, because at 14 MB, it's only a matter of time before he exceeds his bandwidth quota and has to pull the link down.
