Better Sound with the Ess Library
The necessary time delays between each note sent to Roomba makes for a less-than-convincing
theremin simulation. Instead of a smooth tone characteristic of a theremin, the best that can be
done on Roomba is a repetitive beep-beep-beep that is limited by the time it takes the robot to
execute the SONG and PLAY commands.
An optional library for Processing called Ess makes it really easy to load, play, and manipulate
sounds on your computer. It is built on JavaSound (the standard Java sound API), but is much
