Changing the level zoom
To edit the level ruler zoom, use the Zoom In/Out spinner control located above the playbar.
• Clicking the magnifying glass buttons increases/decreases the level ruler
zoom by single-step increments.
• Dragging the spin control increments the level ruler zoom quickly in the corresponding direction.
At high zoom levels, only low-level samples are visible because the peaks of the waveform move beyond the
vertical scope of the data window. Consider the following data windows.
Both data windows display the same audio file at a 1:1 zoom ratio. The window on the left shows the level
ruler zoomed to its maximum out position. The window on the right shows the level ruler zoomed to its
maximum in position. Notice that wave peaks clearly visible in the left window are out of display range in
the right window.
Using zoom level commands
If you prefer using commands, you can control the level magnification from the View menu. The following
table briefly describes the three available zoom level commands. You can access these commands from the
View menu by choosing Zoom Level and choosing the desired command from the submenu.
Formatting the level ruler
You can configure the level ruler to display in decibels or percent by right-clicking the ruler and choosing
Label in Percent or Label in dB from the shortcut menu.
Using custom zoom settings
