Starting and stopping sounds at keyframes

The most common sound-related task in Flash is starting and stopping sounds at keyframes in synchronization with animation.

 
To stop and start a sound at a keyframe:

1

Add a sound to a movie.

To synchronize this sound with an event in the scene, choose a beginning keyframe that corresponds to the keyframe of the event in the scene. You can choose any of the synchronization options. See Adding sounds to a movie.

2

Create a keyframe in the sound layer's Timeline at the frame where you want the sound to end.

A representation of the sound file appears in the Timeline.

3

Choose Window > Properties and click the arrow in the lower right corner to expand the Property inspector.

4

In the Property inspector, choose the same sound from the Sound pop-up menu.

5

Choose Stop from the Synchronization pop-up menu.

When you play the movie, the sound stops playing when it reaches the ending keyframe.

6

To play back the sound, simply move the playhead.
