Possibly incorrect window calculation in documentation
Under "Audio packet decode and synthesis - packet type, mode and window decode", the line: window([i]) = sin(.5 * PI * sin^2( ([i]-[right_window_start]+.5) / [right_n] * .5 * PI/2. + .5 * PI) ) looks like it's got a typo in it, "PI/2.", which generates an incorrect looking curve. Removing it seems to generate the right curve.
