Lite2Sound in Downtown Austin

The urban landscape is secretly generating its own synthesizer soundtrack – with lights as the instruments. This video montage asks, could it evolve into a form of music?

We used an experimental Lite2Sound stereo photodiode amplifier to make field recordings in Austin in December 2022. Lite2Sound has silicon analog sensors that detect small fluctuations in light intensity, amplifying them into audible sounds. The device was mounted under the camcorder with its audio output going into the camcorder’s mic input. The video soundtrack is 100% raw audio from the camcorder – no effects or synthesizers were used.

Lite2Sound devices are available from and in the Rare Waves reverb store. We offer DIY electronics kits and pre-assembled.
