Ultrasonic Scapes

Buzzing of cicadas, pulses of bats, repeated beats from automatic gate, drone sounds from street lights…We usually don’t hear but so many ultrasonic sounds are emitted on the street as well as in nature. Some are intense, continuous and harsh others are pulsing, fragmentary and more harmonious. This is another soundscape documentary beyond our audible range. All ultrasonic sounds were captured and real time converted by bat detector. All tracks are unprocessed except for a little amplification.
