Supplementary material for 'Developing the hertz art-science project to allow inaudible sounds of the Earth and Cosmos to be experienced'

This repositary contains a sample audio clip that has been produced by using an infrasound signal from the Aurora Borealis to manipulate pink noise. In the hertz project this output has been low pass filtered to 120Hz for the hertz playback equipment. It has been low pass filtered at 400Hz here so it is audible through a standard laptop speaker. The video was a clip from a trial development session of the hertz project featuring Juliet Robson.
