OpenAL or Fsound?

Which are the differences ?

Ok, never mind, I readed earlier post.

Just to know, excpet Xbox and other consoles portability, why Fmod is better ?

Depends what your talking about, Fmod or FmodEx.  Hands down FmodEx is the best choice in my opinion… Fmod vs OpenAL… I'd rather go OpenAL.

FmodEx comes with designer tool and supports an insane amount of features… only bad thing about FmodEX is if you plan to make your game commercial you have to pay them, however they will let you use it for only a few hundred bucks if your a small developer.  Check their site for more info.
