About using sounds in Flash Lite
Flash Lite supports two types of sound: standard Flash sounds, like those used in Flash
desktop applications, and device sounds. Flash Lite 1.0 supports device sounds only; Flash
Lite 1.1 supports both standard sounds and device sounds.
Device sounds are stored in the published SWF file in their native audio format (such as
MIDI or MFi); during playback, Flash Lite passes the sound data to the device, which
decodes and plays the sound. Because you can’t import most device audio formats into Flash,
you instead import a proxy sound in a supported format (such as MP3 or AIFF) that is
replaced with an external device sound that you specify.
You can use device sounds only as event sounds—you can’t synchronize device sounds with
the Timeline. Unlike device sounds, you can synchronize standard sounds to the Timeline.
Flash Lite 1.0 and Flash Lite 1.1 do not support the following features available in the desktop
version of Flash Player:
■ The ActionScript Sound object
■ Loading of external MP3 files
■ The Speech audio compression option (see “Compressing sounds for export”
on page 321)
For more information about using sounds in Flash Lite applications, see Chapter 3, “Working
with Sound” in Developing Flash Lite Applications.
