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 displays.

Conversely, if the zoom ratio is 1:1024, 1,024 samples are represented by each point on the screen and a greater length of time displays.

For very precise editing, you may want to zoom in more tightly than a 1:1 ratio. The full version of Sound Forge allows up to a 24:1 ratio, where 24 points on the screen represent one sample. This high level of zoom may be useful when editing with the Pencil tool. For more information, see Repairing audio glitches manually with the Pencil tool on page 140.
