The advent of Python-based networks creates new opportunities for mobile interaction. A compelling application would be interactive graphic control of audio on one device by deft gestures on a remote device. We have developed a stand-alone frequency modulation synthesizer using a Csound audio engine, Python, along with PyGTK and Cairo graphic control, and will extend this to other audio processing algorithms. This development, currently in a Linux environment, can be ported to networked platforms like mobile phones, handheld devices, and the $100 laptop.
