This week I was very happy to present at The Sounds of the Silents, an event at the University of Edinburgh about the history of film sound. There were some amazing lectures and demonstrations from historians and foley artists and more. My presentation was about the Lumièrophone, a screen that I made with Kristina Johansen. As you can see from the photo, this screen has light sensors sewn onto the surface. These sensors control a synthesizer I built that generated sound based on what was projected on the screen. All the sound was thus generated in real time, and without any computers or anything, just a 9 volt battery and some speakers. The Lumièrophone (named after Auguste and Louis)was designed especially for the showing of an abstract film by Walter Ruttman, and I think it worked very well! You can see a video for yourself:
