Re: [Openeeg-list] sound file timing

Ian, AFAIK there is no way how to explore and analyse a piece of sound file in Flash and automatically synchronize with graphics with scripting. But it is very easy to synchronize graphics and sound directly - you see the sound's time domain in flash's timeline and when you go through the timeline (drag the red square, the sound synchronization must be set to "stream") you will hear the sound at current frame - so you will exactly hear where the word begins and ends. To synchronize a word with graphics this way takes few seconds and is just a matter of moving keyframes. I really doubt you find a simple way of automatic synchronizing in any other software.
