Urban noise pollution has been a problem since the days of Buddha. Walkmans help, but issues of both social and accoustic isolation have become more urgent with the popularity of the iPod. Addressing these issues may require a look at how recorded music devices work at a fundamental level. Ambient Addition is a Walkman-like device, built on a DSP core, that synthesizes music by sampling the sound around the listener, creating harmony and rhythm from the chaos and noise of the environment. By simultaneously opening music to incorporate the environment, but also turning the environment into music, the sound stays fresh and the listener is encouraged to explore new territory.
