Selecting audio using start and end values

You can select audio by dragging the mouse or by using keyboard shortcuts (pg. 261). For the sake of accuracy, however, it is often useful to create selections by entering specific start and end point values. The Set Selection dialog allows you to create selections in this way or by choosing a preset selection from the Selection drop- down list.

1.For users of the full version of Sound Forge: from the Edit menu, choose Selection, and choose Set from the submenu.

For users of Screenblast Sound Forge: from the Edit menu, choose Selection. The Set Selection dialog appears.

Press Ctrl + Shift + D .

2.From the Input format drop-down list, choose the format to be used for creating the selection. The values in the Start, End, and Length boxes change to reflect the specified format.

3.Configure the selection by entering appropriate values in the Start and End or the Start and Length boxes.

4.If you are working with a stereo file, choose Left, Right, or Both from the Channel drop-down list.

5.Click OK.
