Flash has four different sync options: event, start, stop, and stream. The event sync enables layering of sounds which may create an amplification effect. The start sync forces you to wait until the end of the track before you can re-trigger the sound. Sometimes, the "Stop before Re-Trigger" technique is best suitable for your needs. It stops any instance of the same frame before start playing a new instance. This technique ensures that the new frame is the only instance playing -- no layering of tracks is allowed. It also allows you to stop the sound immediately instead of waiting for the end of the track (start sync).
