5.
For Quality, select one of the following options to determine the compression speed and
sound quality:
Fast
yields faster compression but lower sound quality.
Medium
yields somewhat slower compression but higher sound quality.
Best yields the slowest compression and the highest sound quality.
Using the Raw compression option
The Raw compression option exports sounds with no sound compression.
To use raw compression:
1. In the Sound Properties dialog box, select Raw from the Compression menu.
2. For Preprocessing, select Convert Stereo to Mono to convert mixed stereo sounds to
monaural. (Mono sounds are unaffected by this option.)
3. For Sample Rate, select an option to control sound fidelity and file size. Lower rates
decrease file size but can also degrade sound quality. Rate options are described in the
following list:
5 kHz
is barely acceptable for speech.
11 kHz is the lowest recommended quality for a short segment of music and is one-quarter
of the standard CD rate.
22 kHz
is a popular choice for web playback and is half the standard CD rate.
44 kHz
is the standard CD audio rate.
Flash cannot increase the kHz rate of an imported sound above the rate at which it
was imported.
Using the Speech compression option
The Speech compression option exports sounds using a compression that is adapted to
speech.
Flash Lite 1.0 and Flash Lite 1.1 do not support the Speech compression option. For
content targeting those player versions, use MP3, ADPCM, or Raw compression.
