An updated version of the machine I created for the RCA Work In Progress show this January:
Inspired by the Leslie speaker, another sound modification device developed by Donald Leslie between the 1930s - 1960s, the Doppler machine is also capable of modulating sound and creating the Doppler effect as the disc with the speakers on, spins around.
It was used as part of a performance with RCM musicians earlier this year, and I'll hopefully continue to develop it and work on further performances and collaborations (If you're a London-based musician, or someone with an interest in sound art, and would like to hear your instrument played through the disc, or to share thoughts, please get in touch!)
