The Magnify Tool |
|
From the Edit menu, choose Tool and then choose Magnify from the submenu to select the Magnify tool.
Use the Magnify tool to zoom in to a particular region without losing your selection. Drag the mouse over an area to zoom in. Sound Forge will draw a dotted rectangle around the area and will magnify the area when the mouse button is released.
While holding the left mouse button, click the right mouse button to toggle through the three magnification modes:
Zoom Time only: magnifies horizontally without changing the vertical level of the data window.
Zoom Level only: magnifies vertically without changing horizontal zoom level of the data window.
Time/ Zoom Level: magnifies horizontally and vertically.
While using any tool, if you hold the Ctrl key down before making
a selection with the mouse, you will switch to the Magnify Tool. This
is handy for quickly magnifying a particular section of your sound file.
