Elisha Gray could have been known to us as the inventor of the telephone. Instead, he goes down in history as the accidental creator of one of the first electronic musical instruments, the "Musical Telegraph." There are many other examples of early electronic instruments, including: the Teleharmonium, the Audion Piano, the Optophonic Piano, the Trautonium, the Ondes Martenot, the Rhythmicon, the Theremin Cello and the better-known Aetherphone (aka Theremin) to name a few. MetaFilter discussed odd music previously.

The research could result in much smaller, more powerful computers and other devices with the ability to process many more channels of high-resolution audio and video than current products can manage. The abstract is available in PDF.
