With the recent advances in EEG technology and the popularization of low-cost mobile EEG devices, brain-computerinterface (BCI) systems and neurofeedback tools have become more accessible. Real-time EEG signal processing isincreasingly popular in the context of digital arts projects powered by a neuroaesthetic approach. CoCo Brain Channelis one such project : designed to use real-time processing of EEG signal in order to generate a musical environment, itprovides the user with a means to hear and control his own brain activity. This is achieved by hooking-up a commercialmobile EEG device to a music generation algorithm built in PureData. The generative algorithm uses features fromEEG signals to modulate harmonic and rhythmic structures of multiple oscillators. The result is a continuous musicalsoundscape reflecting the evolution of EEG signals. Improvements and possible applications for basic research will bediscussed.
