Well I have an Xbox 360 SDK and I need to encode from wma to xma a lot of files, ~1500. How to do that using xmaencode.exe? I found a way to compile only one file per time, not multiple files.
Seriously? >_>.. Microsoft Cross-Platform Audio Creation Tool (XACT). I don't know how you didn't see that, it's right under the only AUDIO folder in the SDK in your start menu.
