INFRASONICON: Time-Compressing Infrasonic Recordings to Discover New Sounds, by Clark Huckaby
The Infrasonicon is a work in progress. My present version demonstrates some ways infrasonic phenomena can be mined for new sounds. In future work, I want to expand the number of channels (to at least stereo) and increase the resolution (to 16-bit). Of course, high resolution is only useful if transducers match such performance. For example, I'd like much better dynamic range, linearity and resolution in a water surface wave transducer. I'm also developing more kinds of transducers, so a wider variety of signals can be captured.
I have posted technical details of my infrasonicon hardware and software (Data Converter, Interface Unit, Optical Probe, Water Theremin, and Audio Amplitude Detector). But if you are interested in making your own channel(s), diverse approaches are possible. For example, perhaps you like to work in software and use ready-made hardware; in that case, you could (for example) write code to convert data files form an oscilloscope module or data logger into sound files, increasing the playback sampling frequency to hear them as sound.
There are many time-compressed infrasonic signals already available on the internet and elsewhere. (I am not the first to use an "infrasonicon" even though I made up the term.) I will provide links to some of these in the near future. For me, much of the fun in hearing time-compressed signals is understanding how they were recorded and the nature of their sources. That's why I plan to publish some sidebar essays addressing topics that you will find pretty diverse. So stay tuned if the infrasonicon idea resonates with you.
As a closing thought, consider the growing global infosphere. Standing at the threshold of a highly networked sensor-rich era (Ref. 10), we will soon be awash in all kinds of data with periodicities at all time-scales. The orthodox approach to its analysis will be to use powerful computational algorithms. But let us not forget the awesome power of the human ear as well. By formatting the data properly for it, a good ear can tell an experienced brain a great deal about the data. And some of the resulting sounds might just be interesting enough to use in music or other cultural artifacts.
