Channel by channel, through the film
One lane per speaker, the whole film from left to right. Bar height is how loud that speaker gets (square-root scale against this film's loudest moment, so quiet passages stay visible). The amber line under a lane marks the moments counted as playing, and the figure on the right is their share of the film. For the six height speakers that share is part of BUBBLE.
