you use it must have the FMod Liabrary Wrapper by DotNet
(FModNet.dll)

Nice would be if you re-publish the code on a website with english language, because most Ogre users doesn't speak Chinese.
It seems so, that you (andyhebear1) are the author. In this case you could use the official repository as host for this add-on. So it's on a central place and can't get lost. (I saw several nice projects, add-ons, tutorials etc. which were on private websites or file hosters and got lost after some months or years. This is sad. So a repository would be more save.)
What do you think about?

What are the experiences of other people?
Did anybody use this library and can give a tiny feedback?
