This August 2014 video says about itself:
Nightingale and Canary
Australian artist Andy Thomas specializes in creating ‘audio life forms’: beautiful abstract shapes that react to sounds. In this animated short, he visualizes two recorded bird sounds from the archives of the Netherlands Institute for Sound and Vision [beeldengeluid.nl] in Hilversum.
This video, from Victoria, Australia, also by Andy Thomas, is called Whip Bird Sound Sculpture test 1.
