How To Build A Synthesizer Made Of Light


In this video, synthesist Frazer Merrick documents his journey of building, composing and performing with a synth that turns light into sound.

Merrick has created a custom synthesizer, Pulsar, that translates Pulse Width Modulation of LED lights into sound. The synthesizer is build around the Photon Smasher, a device that he designed that translates light into sound. As a result, light acts as the sound source of the synthesizer.

The Photon Smasher can be thought of as a microphone for light. Merrick started by using the Photon Smasher as a type environmental sound tool, exploring how environmental lights translate into sound. But he realized that he could also use fixed light sources with the Photon Smasher, and by modulating the frequency and width the LED modulation, he could musically control the resulting sounds.
