It's not really the notch being overwhelmed as such. The deep notch is from cancellation between the direct sound from the speaker and the output of the room's modal response as measured at the listening position. The waterfall shows what happens after the direct sound stops, so in the absence of direct sound the notch rapidly disappears from the plot and what's left is the response of the mode.

I’ve played with the waterfall graphing a little, but not much. Have you seen anything in the program that indicates a time value? It would seem to be a “must have,” since waterfalls are graphing time domain. I’d sure be interested to see what your graphs is showing us in real time. |
The times are shown in the trace labels area of the graph, which shows the time of the front-most slice at the top (changes as you move the slice slider) and the total time span at the bottom.
