Microsoft is making <A HREF="http://www.extremetech.com/article2/0,1558,2164632,00.asp?kc=ETRSS02129TX1K0000532">a tech-demo version of its upcoming DirectX 10.1</A> available via download, including a version of XAudio2, the company's cross-platform replacement for DirectSound.
Users can try out both via the 468MB version of the August 2007 DirectX SDK. There's a catch, though: the August 2007 Direct3D 10.1 Tech Preview requires the Windows Vista SP1 Beta which will be available to MSDN subscribers once it is publicly released.
