4.5.5.2.3 Audio Waveform Panel
The Audio Waveform Panel displays the captured audio waveform. If the waveform is stereo, both channels
are visible in the Wave Panel. The user can view the entire waveform or can zoom to view a portion of the
waveform in more detail.

Waveform
The audio waveform is plotted as amplitude versus time on the Wave Panel. The amplitude
scale is located on the left edge of the Wave Panel. The waveform’s amplitude can be linear
or in decibels. The linear range is -1.0 to +1.0. The range for the dB scale is 0 dB for the
maximum positive and maximum negative values, and silence is negative infinity. A toggle
switch at the bottom of the amplitude scale will switch between
Linear
scale and
dB
scale.
Moving the switch to the left will display the
Linear
scale and moving it to the right will
display the
dB
scale.
Play Cursor
The Play Cursor is identified by a white vertical line on the Wave Panel. The Play Cursor appears when user
clicks on any point in the waveform, or, if the cursor is already present it can be dragged to another position.
To drag the Play Cursor, hover the mouse cursor over the Play Cursor until the mouse cursor changes to a
pointing hand; click and drag the cursor to a new position.
