Dedecahedral speaker array
At CNMAT in Berkeley I was fortunate to work on this project during the summers of 2000 and 2001. CNMAT, the Center for New Music and Audio Technologies, mostly makes avant garde music with the help of new technologies developed there and elsewhere. Being an undergraduate student still working in lower-division, there were not many options open to me, but they gave me this one. I worked on fabrication design of what became to be known as the dodecaphone. At first we were considering having the whole box manufactured with plastic, but luckily we ran across Thomas Harder, a carpenter who could work with many materials besides wood.
Alternatively, the vbap~ object for Max/MSP allows a signal to be panned over the surface of the speaker without resulting in any loudness changes. The "width" of the apparent source can also be adjusted. This method is simpler but still presents many possibilities of different sounds. For example, the differing kinds of reverberation produced by parts of a room can be exploited by beaming the sound in different directions.
The speaker has been used for several concerts as well as experiments on sound cancellation and radiation pattern programming.
