Sound of the Rings of Saturn – A sonification of Space

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.

An interactive sound waves building tool based on live video

The interactive sound waves builder was presented at the Helsinki Hacklab stand at WÄRK:fest, a DIY/Hacker/Culture -festival. The system consists of a small table, webcam and Max/MSP/Jitter process. Visitors were able to manipulate the sound waves by (re)arranging colorful objects on the table.

The table was simultaneously scanned in two dimensions, and the extracted data was used to create the sound waves, pitches and amplitudes for the oscillators. Besides the musical piece the rearrangement of the colorful objects created a transforming visual piece.

Mixing and Mastering Songs for a Movie Soundtrack

A few songs from the soundtrack of Anni, a Finnish indie feature film. The songs have been written, performed and produced by Simo Salo, and they are presented here as mix demos on my behalf.

Workshop about Digital Sound Environment

The workshop was held for theaters’ staff and lasted two hours. The workshop was organized as a part of Teatterilaiva theater festival.

By lightly discussing about the general principles of sound design the attention was drawn to available technology and digital sound processing. Sounds and soundscapes were created by using generally available free software and sound libraries. The workshop provided to be a source of interesting ideas for coming shows.

Sound design for an exhibition

The Finnish Aviation Museum organized an exhibition about flight related myths and legends. The exhibition is called Myyttinen Lento or Mythical Flight in English. The exhibition was designed to spur imagination of kids (and adults). One of the objects of the exhibition was a magic carpet you could ride yourself.

For the design I co-operated with Marko Ahokangas from Dept. of Lighting and Sound Design of Theatre Academy of Finland. Marko created the sounds and I programmed the player. Plogue Bidule was used to create an ever changing and never repeating soundscape, which was fed to an eight channel PA-system, which encompassed the exhibition space.

The location of the sounds in space was controlled by four  separate eight channel linear output selectors, which were modulated by independent sine wave oscillators. The sounds were divided in two categories – fast and slow sounds were panned and controlled by separate sub-programmes.

One layer of the soundscape was a synthesized wind like instrument, which picked its pitch (Via FFT) from the other sounds and acted as the musical element. For example when a sound of an airplane was playing and the synth was trigged the synth picked a frequency from the sound of the airplane and generated a musical tone that was in tune with the sound of the airplane.

Provided here is a two channel sample of the completed soundscape.
