Sodankylä Jam Sessions realised a remote jam sessions, where musicians played their parts at their homes. The recordings were compiled into a song and a video. I post-processed the sound and mixed the song together.
Does the aurora borealis make a sound? At least for some it does.
This is a reproduction of auroral sound experience I had while working as a research assistant at Sodankylä Geophysical Observatory in Finland. It’s very much a personal experience, and this is an approximation of what I heard. For somebody else the experience might differ.
The aurora activity was at about its peak back then in Winter 2001. There were five of us witnessing a very vivid and bright display of northern lights one evening. It first consisted of three parallel belts, which suddenly converged into one right above us. At that point I started to experience a sound, which I had never before heard in my life.
It appeared to create its own space inside my head. There was no reverberation or any traditional sense of space in it. In a way it was really dry and wet at the same time. It sounded like an infinite number of noises layered on top of each other. Each of the layers could be distinguished however, and it had sort of infinite depth in it, but at the same time it felt constrained (to my abilities?).
On top of that there were these very soft and deep intermittent pops.
The sound didn’t change much, but it came and went away according to the auroral display. The sound ended when the single belt divided back to three. The properties of the sound didn’t change even though I moved my head.
I couldn’t believe what happened, and I hesitated telling the others first. There was a project going on at SGO to collect experiences of the sound of auroras, and I also reported mine. I made a reproduction of my experience later that night, and this is more modern version of that.

I recorded the music video and the sound, and mixed it together.

The rings of Saturn look like a spectrogram, so it occurred to me try how it would sound like. In essence, this a sonification of space!
Sound was created by using an authentic image of rings of Saturn as a spectral source to a series of filters. A 1 pixel slice of the image of the rings was extracted
The ring spectrogram was divided into three color planes, and the color intensity values were transformed into resonant filter cutoff frequencies. In essence one filter unit (per color plane) has 256 sounds playing simultaneously. The individual filters are placed along the x-axis so, that the stereo image consists of 256 steps from left to right. The last two sounds were created with 1024 voices and 3×340 voices.
The spectrum was compressed to a couple of ranges. In some sounds a small variation in certain divider factor per color plane is introduced for a slight chorus like effect. The original lossless sound bits are available on Freesound.
