Lyapunov Space of Coupled FM Oscillators
I'm currently enjoying the Linux Audio Conference 2013 in Graz, Austria. On Saturday morning I'll present my paper Lyapunov Space of Coupled FM Oscillators:
I consider two coupled oscillators, each modulating the other's frequency. This system is governed by four parameters: the base frequency and modulation index for each oscillator. For some parameter values the system becomes unstable. I use the Lyapunov exponent to measure the instability. I generate images of the parameter space, implementing the number crunching on graphics hardware using OpenGL. I link the mouse position over the displayed image to realtime audio output, creating an audio-visual browser for the 4D parameter space.
I'll upload the slides and demos soon.
