OSCILLOSCOPE
The Oscilloscope (Figure 9-10) 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 9-10, 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 9-11) provide several
options for the oscilloscope display.
Figure 9-11: View controls.
View menu
The View menu (Figure 9-11) lets you choose how
to display the audio channel(s) being displayed.

the grid displayed in the graph, from 100% (fully
visible) down to 0% (fully hidden). The
