Hello,
I got this crazy idea to attempt to edit the horn sound for the GP7 on the Horse Shoe Curve. To me it sounds like it lacks the natural ambient reverb or echo that a typical horn would create in the real world. So I have this Creative Wave Studio program that came with my Sound Blaster sound card, and thought I would take the horn sound file for that locomotive and add some reverb/echo to it, put it out in the file library (That way I can say I contributed something!

) and enjoy a more realistic horn to play with as I drive along. Sounded easy at first. BUT...where is that file at? Im still baseing my minimal experience with MSTS on this, and each loco had individual files for specific attributes of the model. i.e. cab view, sound, horn, etc.
So based on what I want to do here, I think my "Wave Studio" program might be able to do the task...but

...Ive never actually used it before, so actually I dont know what it can and cant do...Im just assuming here. But if it cant do what Im trying to do, Ill find another program (free) to do it, and in advance, does anyone know of such a program that would be able to edit sound files? (free)
