otomata

29 Apr

Otomata is a generative sequencer. It employs a cellular automaton type logic I’ve devised to produce sound events.

Each alive cell has 4 states: Up, right, down, left. at each cycle, the cells move themselves in the direction of their internal states. If any cell encounters a wall, it triggers a pitched sound whose frequency is determined by the xy position of collision, and the cell reverses its direction. If a cell encounters another cell on its way, it turns itself clockwise.

This set of rules produces chaotic results in some settings, therefore you can end up with never repeating, gradually evolving sequences. Go add some cells, change their orientation by clicking on them, and press play, experiment, have fun.

Over on BLDGBLOG, a discussion with Bryan Pijanowski on sound:

Sound, Pijanowski suggests, is a kind of ecological indicator: an audible symptom of other, sometimes literally invisible changes in a living network or ecosystem. Sound, for instance, can “be used to detect early changes in climate, weather patterns, the presence of pollution or other alterations to a landscape.” As Pijanowski explains one example of this approach, “The dawn and dusk choruses of birds are very characteristic of a location. If the intensity or patterns of these choruses change, there is likely something causing that change. Ecologists have ignored how sound that emanates from an area can help determine what’s happening to the ecosystem.”

Not too long ago, I mentioned using dawn- and dusk-time birdsong as a clock, a practice still of some Papua New Guineans, but one that’s faded from American communal memory. Here, Pijanowski looks to birdsong not for the time but for a prediction of the future—or rather for signs of changes already set in motion.
