Using the sound-editing controls

To define the starting point of a sound or to control the volume of the sound as it plays, you use the sound-editing controls in the Property inspector.

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

To edit a sound file:

1 | Add a sound to a frame (see Adding sounds to a movie), or select a frame already containing a sound.
2 | Choose Window > Properties.
3 | Click the Edit button on the right side of the Property inspector.
4 | 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 Edit Envelope.
| To change the sound envelope, drag the envelope handles to change levels at different points in the sound. Envelope lines show the volume of the sound as it plays. To create additional envelope handles (up to eight total), click the envelope lines. 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 or Out buttons.
| To switch the time units between seconds and frames, click the Seconds and Frames buttons.
5 | To hear the edited sound, click the Play button.
