A _very_ roundabout way... You can set the bitrate of mp3, and using 
FLfile.getSize(fileURI) you can get the file size of the swf, so it 
should be possible to change the bitrate, export the swf, find the 
change in filesize which will be the change in size of the mp3, 
calculate the size of the mp3 based on change in size and change in 
bitrate, find the length in seconds by dividing the mp3 size on the 
bitrate... as I said a very roundabout way which you must be desperate 
to use.
