This is a .aud player that can be used in both Windows or DOS.
This is the first beta of my new AUD Player for Windows, which will also be used in RA-MIXer 6.0 for Windows (not released yet!). AUD Player for Windows does NOT work with RA-MIXer 5.x, so don't try to use it as an add-on.
AUD Player works like the Media Player in Windows, but has less functionality (forward + backward or not working yet). I'll probably add these things to later betas -- that means this version (beta 1) is NOT feature complete!
As AUD Player is able to read FileNames that are passed to it using parameters, you can also associate the extension "AUD" with AUDPLAY.EXE (in your Windows Explorer!). If you don't like to do so, you can open files inside AUD Player using the "Open..." command from the file menu.
