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.<div>
<br></div><div>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.<br>

<div><font face="Tahoma" color="#808080" size="2">hmm..., sure i've noticed the
<em>delta v </em>and <em>delta t</em> constrains at both: sonogram and matrixes
above, but it still look different to me. i'm musician, and at my first
[and the second :)] glance i see on sonogram kind of rhythmical points with a
different harmonics composition, and matrixes show to me something like fluent
crescendo and then diminue,do process of one complex sound . Do <em>delta v</em>
and <em>delta t</em> show the same periods both at matrixes and sono? No i
still can't find and similarities. Maybe it's more clear for any phisician
?</font></div>
