Scrubbing with the audio event locator
Dragging the mouse within the overview bar initiates playback of small audio loops adjacent to the cursor position. This is not

events within a file. Playback stops when the mouse button is released.

Zooming and magnifying
Because there are considerably more samples in a sound file than horizontal points (pixels) on the screen, many data samples must be
represented by each horizontal point when audio data displays in the data window. Depending upon the editing operation, you may

time ruler zooming and level ruler zooming. You can also zoom to events when using the Event tool (

Zoom ratio
Understanding the zoom ratio
The zoom ratio determines the number of samples represented by each horizontal point on the screen. The zoom ratio is a value of X:Y,
where X is the number of horizontal points and Y is the number of samples. If the ratio is 1:1, each point on the screen represents one
sample. At this zoom ratio, a brief but detailed selection of time is displayed.

For very precise editing, you may want to zoom in more tightly than a 1:1 ratio. Sound Forge allows up to a 24:1 ratio, where 24 points on
the screen represent one sample. This high level of zoom can be useful when editing with the Pencil tool (
