Director allows a variety to methods to play sound.
You can import sound as a linked member, which streams the sound data incrementally from disk as it plays, allowing large sound files to play even in low memory configurations. Director itself imposes few practical limitations. Note that, in general, the likelyhood of success increases with less complex data. For example, an 8-bit, mono, 11.025 kHz, uncompressed, .WAV sound file is usually the most likely to play correctly on most Windows systems. There are many possible reasons why sound might not play, or a certain sound might interfere with other Director functions.
