View menu
The View menu (Figure 9-10) lets you choose how
to display the audio channel(s) being displayed.
View menu settingWhat it displays
Left Left channel only
Right Right channel only
Split screen Left channel on top; right channel on the bot-
tom
Shared Left and right on top of each other; left is
green, right is red
Add Left and right channels' amplitudes are added
together
Subtract L-R The right channel's amplitude is subtracted
from the left channel's amplitude
Display options
The Axes control (Figure 9-10) sets the opacity of
the grid displayed in the graph, from 100% (fully
visible) down to 0% (fully hidden). The Show Ruler
option toggles the measurement items (see
"Measurement information" on page 95).
Pausing the display
The Pause button in the upper right corner of the
View section (Figure 9-10) allows you to freeze the
display at any time. To resume, click the button
again. The level meters will remain active while the
display is paused.
Horizontal controls (time axis)
The Horizontal controls (Figure 9-11) configure
the value range of the x-axis (time). Click and drag
the values up or down to set them, or double-click
to return to the default value.
There are two modes for the controls: Zoom/Offset
and Min/Max. To change the mode, use the
Horizontal control menu (Figure 9-11).

Figure 9-11: Horizontal controls.
In Zoom/Offset mode, Zoom sets the display zoom
from 1/1000x to 10x, where the number represents
the number of pixels per sample. For example,
when the horizontal zoom value is 10x, 10 samples
are displayed in 100 pixels; when the horizontal
zoom value is 1/10x, 100 samples are displayed in
10 pixels. Pos moves the line marking time equals
zero left or right.
In Min/Max mode, Min and Max set the earliest
and most recent displayed time.
Time Units
The Time Units sub-menu (Figure 9-11) provides
the option to view the X axis in Seconds or
Samples.
Vertical controls (amplitude axis)
The Vertical controls (Figure 9-9) operate similarly
to the Horizontal controls, except that they
configure the y-axis (amplitude).
In Zoom/Offset mode, Zoom sets the display zoom
from 1/2 to 100x, and Pos moves the line marking
amplitude equals zero line up or down.
In Min/Max mode, Min and Max set the smallest
and largest displayed amplitude.
Waveform Recognition
The Waveform Recognition option (Figure 9-9)
searches through new audio data looking for a
waveform which most resembles that which was
previously displayed. The region where this takes
place is a small window around the line marking
time equals zero, denoted by the extra vertical
graph lines surrounding it. There are two kinds of
waveform recognition available: Type I and
Type II.
