"Greg Hooper's EEG Sonification, like Neural Dialogues and Polyrhythms, seeks to isolate a particular feature of scientific interest in the large dataset and sonify that. Mr. Hooper uses the General Mutualized Information algorithm to calculate a non-linear correlation between all possible pairs (26!) of the EEG signals, sonifying only those channels that exceed a threshold correlation coefficient. Substantial domain-specific data reduction by external algorithms before sonification is yet another consideration in the design process. Mr. Hooper's piece is effective since there are periods of sparse correlation (hence very quiet) that contrast well, from a musical standpoint, with the busier sections."
