I am pretty much doing the art direction on this thing, but I am working on sound effects too. As you might guess there are not enough people or enough money, but that is the way it is and so we are going to do the best we can. At the moment I am looking for sound files, if you go to http://www.trainhornsunlimited.com you can see what I mean. They sell a lot of ridiculously expensive air horns, I guess you are supposed to put them on cars, although that does not seem like a good use for them or a very simple idea. At any rate if you look closely you will see the pictures and the descriptions of the horns that they sell and you will see a little audio applet. That is supposed to show you what the air horn sounds like, although I suspect that it is going to be a lot louder than your computer will be if you listen to that file.
I found those when I was looking around and we were hoping for a bit that the sound files they had would be good. This is going to take part on an old train. It is set around 1935 when trains were the main way that you got around the country. That was not the original plan, but we adapted it because we found an existing stage set that was quite nice. It was a cost saving measure, which is important when you are trying to make something on a shoe string budget like we are. It was not that big of a deal to me, as I had not started on anything which mattered and this makes my job a bit easier in many ways. There is less variation in the scenery.
