7 Select an effect option from the Effects pop-up menu:

None Applies no effects to the sound file. Select this option to remove previously applied effects.

Left Channel/Right Channel Plays sound in the left or right channel only.

Fade Left To Right/Fade Right To Left Shifts the sound from one channel to the other.

Fade In Gradually increases the volume of a sound over its duration.

Fade Out Gradually decreases the volume of a sound over its duration.

Custom Lets you create custom in and out points of sound using the Edit Envelope.

8 Select a synchronization option from the Sync pop-up menu:

Note: If you are placing the sound on a frame other than Frame 1 in the main Timeline, select the Stop option.

Event Synchronizesthesoundtotheoccurrenceofanevent.Aneventsound,suchasasoundthatplayswhenauser

clicks a button, plays when its starting keyframe first appears and plays in its entirety, independently of the Timeline,

even if the SWF file stops playing. Event sounds are mixed when you play your published SWF file. If an event sound

is playing and the sound is instantiated again (for example, by the user clicking the button again), the first instance

of the sound continues to play and another instance begins to play simultaneously.

Start The same as Event, except that if the sound is already playing, no new instance of the sound plays.

Stop Silences the specified sound.

Stream Synchronizes the sound for playing on a website. Flash forces animation to keep pace with stream sounds.

If Flash can’t draw animation frames quickly enough, it skips frames. Unlike event sounds, stream sounds stop if the

SWF file stops playing. Also, a stream sound can never play longer than the length of the frames it occupies. Stream

sounds are mixed when you publish your SWF file.

An example of a stream sound is the voice of a character in an animation that plays in multiple frames.

Note: If you use an mp3 sound as a stream sound, you must recompress the sound for export. You can export the sound

as an mp3 file, with the same compression settings that it had on import.

9 Enter a value for Repeat to specify the number of times the sound should loop, or select Loop to repeat the sound

continuously.

For continuous play, enter a number large enough to play the sound for an extended duration. For example, to loop

a 15-second sound for 15 minutes, enter 60. Looping stream sounds is not recommended. If a stream sound is set to

loop, frames are added to the file and the file size is increased by the number of times the sound is looped.

10 To test the sound, drag the playhead over the frames containing the sound or use commands in the Controller

or the Control menu.

Synchronize a sound with animation

To synchronize a sound with animation, you start and stop the sound at keyframes.

1 Add a sound to a document.

2 To synchronize this sound with an event in the scene, select a beginning keyframe that corresponds to the

keyframe of the event in the scene. You can select any of the synchronization options.

3 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.
