Adding Sounds To Buttons - MACROMEDIA FLASH MX 2004-USING FLASH Use Manual

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. For more
information, see
Select a synchronization option from the Sync pop-up menu:
8.
Note: If you are placing the sound on a frame other than Frame 1 in the main TImeline, select
the Stop option.
Event
synchronizes the sound to the occurrence of an event. An event sound 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.
An example of an event sound is a sound that plays when a user clicks a button. 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
is 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. For
more information, see
Enter a value for Repeat to specify the number of times the sound should loop, or select Loop
9.
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.

Adding sounds to buttons

You can associate sounds with the different states of a button symbol. Because the sounds are
stored with the symbol, they work for all instances of the symbol.
To add sound to a button:
Select the button in the Library panel.
1.
Select Edit from the options menu in the upper right corner of the panel.
2.
In the button's Timeline, add a layer for sound.
