Using the sound-editing controls

Use the sound-editing controls in the Sound panel of the Frame Properties dialog box to define the starting point of a sound or to control the volume of the sound as it plays.

Flash can change the point at which a sound starts and stops playing. This is useful for making sounds smaller by removing unused sections.

To edit a sound with the sound editing controls:

1	Add a sound to a frame (see Adding sounds to a movie), or select a frame already containing a sound and choose Modify > Frame; then click Sound in the Frame Properties dialog box.
2	Do any of the following:
	To change the start and end points of a sound, drag the Time In and Time Out controls in the Sound Frame Properties dialog box.
	To change the sound envelope, drag the envelope handles on the envelope lines to change levels at different points in the sound. Envelope lines show the volume of the sound as it plays. Click on the lines to create up to eight envelope handles. To remove an envelope handle, drag it out of the window.
	To display more or less of the sound in the window, click the Zoom In/Out buttons.
	To switch the time units between seconds and frames, click the Seconds and Frames buttons.
