Figure 9-7: The Vertical controls.
In Zoom/Offset mode, Zoom sets the display zoom
from 1x to 100x, and Pos sets the center amplitude
of the graph. In Min/Max mode, Min and Max set
the smallest and largest displayed amplitude.
Spectrogram controls
The Floor control (Figure 9-8) sets the amplitude
threshold for the spectrogram display, from -144
dB up to 0 dB.
Figure 9-8: The Spectrogram controls.
The Alpha control (Figure 9-8) sets the opacity of
the spectrogram information displayed in the
graph, from 100% (fully visible) to 0% (hidden).
OSCILLOSCOPE
The Oscilloscope (Figure 9-9) graphs the
amplitude of an audio signal over time.
Amplitude is displayed on the y-axis and time is
displayed on the x-axis. A thick white vertical line
marks where time equals zero; a thick white
horizontal line marks where amplitude equals zero
(Figure 9-9, below).
Level meters are displayed to the right of the graph.
One or two meters are shown, depending on the
current view mode (see “View controls”).
View controls
The View controls (Figure 9-10) provide several
options for the oscilloscope display.
