I have no way of synchronizing the sounds to the speed of the train, that requires active sound generation and not just playing recorded sounds. That enters a whole different dimension, you can ask Rudy from Lionel about that, he's their sound guy. I am going to have a sensor input so I can tell if I'm moving or stopped.
At some point, I might consider sensing speed and switching recordings based on relative speed, but that would be down the road. This would simply be switching the soundtrack I was playing based on speed. The good part is I can play a virtually unlimited number of sound clips, and track selection is software controlled, so I can tune it at a later date.
Another big issue would be obtaining realistic sound clips at various road speeds as well, any ideas?
