Adobe® 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 and 2.x support 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, as you can with standard sounds.

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
