Top of the Chasm was recorded where the steep rocky cliffs of the Zambezi River Gorge reverberate with the sounds of rushing water. Recorded at the top of the chasm, overhanging the river far below, the sound of running water is blended and modified by the morning air and multiplied by echoing cliffs yielding a unique river gorge sound.
The deep gorge is a result of waterfall erosion that takes thousands of years to create. It is an ongoing process that we can only participate as reverent observers because the magnitude of the forces and time the process requires are beyond our intuitive comprehension. This unique peacefulness of the gorge sound is a result of a natural merging of the effects of vast volumes of air and water.
Behind a bend in the gorge and half a kilometer away, the waterfall still plummets, as the geological process is never-ending. That ancient presence is represented in the recording as a sub bass rumble at about 10 Hz (10 Hz is the same frequency as alpha brain waves), created as the massive amount of water tumbles down 108 meters (360 feet) and shakes the earth.
Top of the Chasm is a natural soundscape composed of a digital stereo binaural field recording. Recorded above the Zambezi River downstream from Victoria Falls in southern Zambia, Africa. Encoded at a bitrate of 192 kbps for quality listening.
