About 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.
If you select global compression settings for event sounds or stream sounds in the Publish Settings dialog box, these 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.
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.
Compress a sound for export
1. Do one of the following:
Double-click the sound’s icon in the Library panel.
Right-click (Windows) or Control-click (Macintosh) a sound file in the Library panel and select Properties from the context menu.
Select a sound in the Library panel and select Properties from the Panel menu in the upper-right corner of the panel.
Select a sound in the Library panel and click the Properties button at the bottom of the Library panel.
2. If the sound file has been edited externally, click Update.
3. For Compression, select Default, ADPCM, mp3, Raw, or Speech.
The Default compression option uses the global compression settings in the Publish Settings dialog box when you export your SWF file. If
you select Default, no additional export settings are available.
4. Set export settings.
5. Click Test to play the sound once. Click Stop if you want to stop testing the sound before it finishes playing.
6. Adjust export settings if necessary until the desired sound quality is achieved, and then click OK.
ADPCM and Raw compression options
ADPCM compression sets compression for 8- or 16-bit sound data. Use the ADPCM setting when you export short event sounds such as button
clicks.
Raw compression exports sounds with no sound compression.
Preprocessing Converts mixed stereo sounds to monaural (mono) when you select Convert Stereo To Mono (mono sounds are unaffected by
this option).
Sample Rate Controls sound fidelity and file size. Lower rates decrease file size but can also degrade sound quality. Rate options are as
follows:
5 kHz Barely acceptable for speech.
11 kHz The lowest recommended quality for a short segment of music and one-quarter the standard CD rate.
22 kHz A popular choice for web playback and half the standard CD rate.
44 kHz The standard CD audio rate.
Note: Flash Professional cannot increase the kHz rate of an imported sound above the rate at which it was imported.
ADPCM Bits (ADPCM only) Specifies the bit depth of the sound compression. Higher bit depths produce higher quality sound.
