The FitzHugh-Nagumo ("FHN") model is a "relaxation oscillator" that approximates the excitation of squid neurons. It exhibits chaotic behavior that, when sonified, moves from pure tones to overtone-rich buzzes to white noise. The sonic material here is made up of networks of FHN oscillators. These produce idiomatic, speech-like phrases that are tracked for silences and used to trigger changes in speed / timbre / density. The results are arranged in non-linear, contrasting plateaus. This is a downmix of a quad recording.
