I'm making a rhythm game and I need a quick way to get the length of an ogg file. The only way I could think would be to stream the file really fast without playing it but if I have hundreds of songs this would obviously not be practical. Another way would be to store the length of the file in some sort of properties file but I would like to avoid this. I know there must be some way to do this as most music players can tell you the length of a song.
