About sound in Flash Lite

Flash Lite 2.0 supports two types of sound: standard (native) Flash sound and device sound. Native sounds are played directly by the Flash Lite player, just as they are in the desktop version of Flash Player. With some exceptions, you can use native sounds in your Flash Lite application as you would use them in a Flash desktop application. For more information about using native Flash sounds, see Using native Flash sounds.

Device sounds, in contrast, are played directly by the device, rather than by the Flash Lite player. Some examples of device sound formats include MIDI or MFi, but supported sound formats vary from device to device. To use device sounds, you can either bundle them in the published SWF file, or you can load external sound files from a network location or the device's local file system. Device sounds have some limitations that don't apply to native sounds. For more information about using device sounds, see Using device sound.
