Ultraworld, Jana Winderen, 2012
All sound is invisible; ultrasound is inaudible. Of course, many species have a greater range of hearing than us humans... dogs, for example, can hear the silent whistle we blow... this is the mysterious world of ultra sound.
Both creatures on land and under water produce and/or perceive very high frequencies. Some species of insects, birds, fish, and mammals can emit and hear ultrasound, used for communications, hunting and orientation. These creatures operate on a different level of perception to us, in an inaudible range above 20kHz...
The mix for the piece is based on ultra sound recordings made with specialist microphones above and below the water. The recordings were made in various locations in Russia, Thailand, England, Norway, Denmark and Sweden. The sound is time stretched to bring it into a frequency area audible for human beings.
The piece is co-produced by Touch (UK)
Spatial audio software programming by Prof Tony Myatt.
Recordings made with a Pettersson D1000X ultrasound detector, Batbox duett, Reson 4032 and DPA hydrophones onto a Sound Devices 477T recorder.
