It calculates the average alpha and beta wave level from the first two channels (0,1).

    • All eight channels were working fine. In the video I was playbacking a file with only the first two channels recorded. And the reason the use the first two is like that two channels appeared to be sufficient (though scientifically you could use more), and it is an easier hacky way to adapt to different head sizes, since we only had size L at hand (my head was smaller than that but I could still get the first two attached).
