How to make new sounds?

[griffinrails]

Hi all.
I'm working on a couple of my mods, and I'm trying to figure out how to make new sound effects such as horns, engine sounds and how to make a new forest sound.
Does anyone know how to make any? Stuff like what kind of audio format and XML coding info would be very appreciated.

P.S. How can I add a new forest sound effect? Will it make a new tab in the advanced scenario editor or will I just have to replace the existing sound?
P.S.S. What is the forest sound even called?

all sound files must have a .wav file and a .xml file with this configuration. and you must comple both together with wrapper.

I am not sure. But I think the sound from the forest comes from the .exe file. If necessary, I don't know a file with this effect.

I think he wants to make an invisible vehicle that has a forest sound. Not to sure about that though.

Walter's guess is right, it's the sounds that occurs when several trees are added.
Thanks for the help norfolksouthern16.

I've made a test sound for the SAR Redhen Railcar, one of Walter's assets. It's being tested on a built in DAT at the moment, should go all to plan.
