Compressing Sounds For Export - MACROMEDIA FLASH MX 2004-USING FLASH Use Manual

Compressing sounds for export

You can select compression options for individual event sounds and export the sounds with those
settings. You can also select compression options for individual stream sounds. However, all
stream sounds in a document are exported as a single stream file, using the highest setting of all
those applied to individual stream sounds. This includes stream sounds in video objects.
You select compression options for individual sounds in the Sound Properties dialog box. You
can also select global compression settings for event sounds or stream sounds in the Publish
Settings dialog box. These global settings are applied to individual event sounds or all stream
sounds if you do not select compression settings for the sounds in the Sound Properties dialog
box. For more information, see
You can also override export settings specified in the Sound Properties dialog box by selecting
Override Sound Settings in the Publish Settings dialog box. This option is useful if you want to
create a larger high-fidelity audio file for local use and a smaller low-fidelity version for the web.

The sampling rate and degree of compression make a significant difference in the quality and size
of sounds in exported SWF files. The more you compress a sound and the lower the sampling
rate, the smaller the size and the lower the quality. You should experiment to find the optimal
balance between sound quality and file size.
When working with imported MP3 files, you can export the files in MP3 format using the same
settings that the files had when imported.
Note: In Windows, you can also export all the sounds from a document as a WAV file using File >
Export > Export Movie. For more information, see
on page 345.
