Well , almost.
But here's a neat idea. We all know about brainwaves right? That they change depending to what we're doing? For instance, the brainwaves of a sleeping person are vastly different than the brainwaves of someone wide awake. When the brain is given a stimulus, through the ears, eyes or other senses, it emits an electrical charge in response, called a Cortical Evoked Response. These electrical responses travel throughout the brain to become what you "see and hear". This activity can be measured using sensitive electrodes attached to the scalp.
So where am I going with all this? Well what if you could create the buzz you get from a cup of coffee, just by listening to a sound?
That's exactly what Anabubula.com has done. They've made a 20 minute stimulating mp3 to give you energy. Download Squad gave it a listen and said "The sound file sounds like a nature tape (birds chirping, etc) mixed with what seems like random noise at a very slowly escalating pitch. I was surprised how much it affected me; a couple of times I found myself actually becoming anxious, before realizing that I was simply being manipulated (by my own doing) by a sound file. Crazy, eh?" I'm downloading it now so I can work all night!
