[microsound] Gabor's matrix vs. Xenakis' screens

[Paulo Mouat]

I don't read it as displaying the same info. The two grids at the top
display the same information, the crescendo-diminuendo you talk about; the
sonogram at the bottom has a lot more going on. It looks like the grids are
displaying a single strand of one of the events in the sonogram. I don't
think they were meant to match.

Essentially, the information contained in the Gabor matrices is time along
the horizontal axis, frequency along the vertical and intensity represented
numerically or as the size of the circles. The evolution of the sound is
read from left to right. Xenakis' screens represent frequency and intensity
along the axes, with a single screen representing a single moment in time; a
sequence of screens (or a "book") will represent the evolution of the sound
over time, just like frames in a movie.
