      What's New in the November 2007 DirectX SDK

      This version of the DirectX SDK contains the following new features, tools, and documentation.

      Changes in Visual Studio Support

      The March 2008 DirectX SDK will include support for Visual Studio 2008. At the same time, the DirectX SDK will drop support for Visual Studio 2003 while continuing to maintain support for Visual Studio 2005.

      XAudio2 Beta Improvements

      This release includes several new features.

      • XAPO is a new DSP plug-in model. Using XAPO,developers can write and use their own DSP effect in XAudio2 applications.
      • XAudio2 now supports ADPCM on Windows. In addition, the ADPCM encoder tool, adpcmencode.exe, enables creation of ADPCM content.
      • XAudio2 source voices can now run without source data. This is useful for oscillator modeling or other generative audio effects.
      • Using IXAudio2::RegisterForCallbacks and IXAudio2::UnregisterForCallbacks, developers have more flexibility in registering callbacks in XAudio2, allowing them to be registered or unregistered on the fly.
      • Using IXAudio2Voice::GetVoiceDetails, developers can get the creation flags, input channels, and sample rate of a voice.
      • Using IXAudio2SourceVoice::Discontinuity, developers can indicate that a voice is not to expect any more buffers after the last one that is currently in its queue.
      Holiday 2008 titles may want to consider switching to XAudio 2, since no changes will be made to XAudio going forward.

      New and Updated Samples

      This release has several new samples.

      • The AdvancedParticles sample shows a particle system that interacts with its environment. The system is managed entirely by the GPU.
      • The GPUBoids sample shows a flocking algorithm managed entirely by the GPU.
      • The NBodyGravity sample shows an n-body particle system managed entirely by the GPU.
      • The XAudio2BasicSound sample demonstrates how to initialize the XAudio2 library and play a variety of sounds files.
      • The XAudio2Sound3D sample demonstrates how to use XAudio2 with the X3DAudio library for spatialized audio.

      Known Issues with the November 2007 SDK

      XAudio2: Queries about Volume, Pitch, Frequency Ratio, and Filter Parameters May Not Return Currently Set Values

      In the August 2007 and later SDKs, changing state (such as the volume, pitch, frequency ratio, filter parameters, and others) is deferred. The following methods will all return the most recently set value, even if that value hasn't yet been applied to the sounds.

      • IXAudio2Voice::GetChannelVolumes
      • IXAudio2Voice::GetOutputMatrix
      • IXAudio2Voice::GetVolume
      • IXAudio2SourceVoice::GetFilterParameters
      • IXAudio2SourceVoice::GetFrequencyRatio
      In a future release of the SDK, these methods will return the values that are currently applied to the sounds.

      Microsoft Cross-Platform Audio Creation Tool (XACT)

      The Microsoft Cross-Platform Audio Creation Tool (XACT) has the following issues:

      • Users of XACT must explicitly create a new project (or open an existing one) before any object creation will be enabled. To create a new project after launching the authoring tool, select New Project from the File menu and specify the location and filename for the project.
      • The peak LED meters in the XACT auditioning monitor may get stuck. Users can choose to ignore this and let other playing content clear the stuck meters. As long as content is playing, the peak LED meters will eventually clear. Alternatively, users can right-click on the level meters and select Clear Clip LEDs.
      DXGI: Cross-Process Shared Surfaces not Supported in the Reference Rasterizer

      Cross-process shared surfaces are not supported when using the Reference Rasterizer.

      Symbols for DirectX

      The latest and most complete source for debugging symbols is the Microsoft Symbol Server. We recommend using the symbol server rather than using the included partial symbols package. For instructions on using the Microsoft Symbol Server, see

      Windows 95, Windows 98 and Windows ME Are Unsupported by the DirectX SDK

      Starting with the December 2006 SDK, the DirectX SDK does not support targeting of applications for Windows 95, Windows 98, Windows 98 SE, or Windows ME. The D3DX DLL does not install or load on these legacy operating systems. To support these legacy operating systems, use the October 2006 SDK or an earlier version.

      Installation Notes for All Platforms

      • This SDK installs on Windows XP, Windows Server® 2003, and Windows Vista using Visual Studio .NET 2003 or 2005.
      • Before installing the current DirectX SDK, remove previous versions of the DirectX SDK.
      • Some samples require that you install the latest Microsoft Windows SDK (Platform SDK) on your system.
      • If you encounter compilation issues related to the DirectX headers, make sure that the include directories in Visual Studio are set correctly. On the Win32 platform, make sure that there is a reference to the DirectX headers. "$(DXSDK_DIR)include" should appear in the include directory "$(VCInstallDir)Include."
      • SDK Installation to a network share is not supported. Some components (documentation and managed samples) do not run.
      • Several virus protection software applications interfere with SDK installation. They may require you to disable virus protection software until SDK installation is completed.
      • If you encounter the error message "A cabinet file is necessary for installation and cannot be trusted" during installation, your system may be corrupted, or cryptographic services may be disabled. To resolve the problem, try the following:

        1. Enable cryptographic services. On the Start menu, right-click My Computer, and then click Manage. The Computer Management window appears. In the left navigation pane, click Services and Applications. In the right pane, double click Services, and then double-click Cryptographic Services. The Cryptographic Services Properties property sheet appears. On the General tab, make sure that Service Status is Started, and that Startup Type is Automatic.
        2. If you are running Windows on a FAT32 drive, run scandisk.
        3. Try the resolution steps in Detecting digital signing issues in Windows XP.
        4. Try the resolution steps in You cannot install some updates or programs.
        5. Remove temporary files in %temp%. If you are installing end-user runtime, also remove "%windir%\system32\directx\websetup Error."
      • External firewall programs may indicate that the file InstallDeveloperFiles.exe wants to access the Internet. This is by design, and should be enabled.
      Installation Notes for Windows Vista

      Running Microsoft_DirectX_SDK.msi instead of setup.exe requires that you run as administrator. If you install by using setup.exe instead of the MSI, you will be prompted for elevated permissions before the installation can succeed.

      The DirectX SDK No Longer Contains...

      The DirectX SDK no longer contains the following components:

      • Direct3D8 and all of the earlier versions
      • Direct3D RM
      • DirectAnimation
      • DirectMusic
      • DirectInput7 and all of the earlier versions
      • DirectPlay
      • DirectPlayVoice
      • DirectX8-era HRESULT conversion routines
      • Managed DirectX samples and documentation
      Developers wanting to use these components will need to download the August 2007 DirectX SDK, available from MSDN.

      The REDIST and Web DXSetup have not been not be affected by these removals.
