20Hz Geo Magnetic Storms as Audio Sculpture


20 Hz observes a geo-magnetic storm occurring in the Earth’s upper atmosphere. Working with data collected from the CARISMA radio array and interpreted as audio, we hear tweeting and rumbles caused by incoming solar wind, captured at the frequency of 20 Hertz. Generated directly by the sound, tangible and sculptural forms emerge suggestive of scientific visualisations. As different frequencies interact both visually and aurally, complex patterns emerge to create interference phenomena that probe the limits of our perception.

 

I don’t think you really need to understand exactly how this was created, it’s nice to look at, sounds interesting and space made it, enough said really!

But seriously this reminds me of the times I used to spend sitting in front of my friends awesome projector while I was a student, we would sit there listening to our favourite tracks while staring at the output from the Winamp plugin Milkdrop. Beautifully hypnotic.

I digress however, just watch the video. I really wish this was how we visualised audio with our test equipment in the studio! This video was created by Semiconductor and will be on show as part of the Invisible Fields exhibition at Arts Santa Monica in Barcelona Spain. Go to www.lighthouse.org.uk you should also check out the ‘Light painting WiFi’ too, I had an idea about doing this a while ago and I’m just glad someone has done it and done it well.
