Chapter 13. Animation > Adding sound

Adding sound

Sounds add a whole new dimension to Web pages. Sounds can be fun, beautiful, or irritating, but they're hard to ignore. LiveMotion supports the .aif, .av, QuickTime, and .wav sound file formats.

To add sound to an animation:

If the sound you want to use is not already on the Sounds palette, drag the sound file icon from the Desktop into the Sounds palette. Or, in the Mac OS Finder or in Windows Explorer, drag the sound file you want to use into the Adobe LiveMotion > Sounds folder, then relaunch LiveMotion.

Position the current time marker at the time when you want the sound to occur.

Show the Sounds palette. Click a sound icon, then drag the sound icon from the palette into the composition window or into the Timeline to place the sound in the main composition (Figs. 12).

Figure .


In the Timeline editor, double-click a time-independent object, position the current time marker, then drag the sound icon onto the time-independent Timeline or onto the object in the composition window to place the sound in that independent timeline.

The sound will automatically be added to the timeline as a separate object at the current time marker position.

Position the sound duration bar and adjust the start and end points. Shorten the duration to truncate the sound; lengthen the duration to cause the sound to loop. The delicate vertical lines that appear on the duration bar mark where the sound is repeated (Fig. 3).

To sync a sound with an object change or motion, reposition or extend the sound duration bar so its vertical line aligns with the frame where the object change or motion occurs.

Optional: Expand the Object Attributes list under the sound object name to access the Pan and Volume sound properties. Pan causes the sound to move from the left stereo channel to the right stereo channel. Volume controls the loudness of the sound (Fig. 1). Use the Properties palette to change the current values for these properties (Fig. 2). Set keyframes to animate these properties as you would for any property. Align the sound keyframes with object change keyframes to have pan and/or volume changes sync with object transitions.

Sound options

These Sound options are available on the pop-up menu on the Properties palette:

Event Sound

The sound will play after it has downloaded and will be stored in memory for reuse. Use this option for a sound that plays more than once at separate points on the timeline.

Solo Event Sound

The sound will play in response to a mouse event, but all other playbacks of this sound will stop once the sound is played. This will prevent the sound from playing several times if the button to which it is attached is clicked on repeatedly.

Choose an option from the pop-up menu on the Properties palette (see the sidebar).

Figure .

▸ All sounds that are added to a composition become objects in the timeline (with the exception of a sound that is attached to a selected rollover state other than Normal via the Rollovers palette).

▸ Additional sound files are contained in the Adobe LiveMotion > Goodies > Sounds folder.

▸ All sounds from LiveMotion are exported to the MP3 format, but LiveMotion can't import MP3 sounds.
