Well... thanks Mike, but those two hints were fairly obvious in the video.
I'd already done all kinds of bit-shifting and bit-rotating operations I can think of (shift vs rotate, per octate vs. per the whole stream, right vs. left, 1-7 positions, etc), but nothing comprehensible comes out. However, the meaning of the pie I have not been able to figure out...
Next clue please.

Hint, pleeeeease! I'm thinking about this so much it is starting to adversely affect my relationship! But not too many or too easy hints at once - just one small clue at a time!
