Please refer to Download the Windows Driver Kit for instructions on how to download and install each one.įrom the Visual Studio Installer, the following individual packages must be installed in order to build SysVAD: Setup the development computerįor building the sample driver, the following components must be installed: Perform the following steps to build this sample driver. Instructions are provided in Run the sample to show you how to set up the target computer - also referred to as provisioning a target computer. If, however, you would like to deploy, run and test this sample driver, then you need a second computer that will serve as your target computer. If you simply want to build this sample driver and don't intend to run or test it, then you do not need a target computer (also called a test computer). This APO demonstrates the use of echo cancellation interfaces that an AEC APO uses to obtain reference audio for cancellation.įor more information about the Windows audio engine, see Hardware-Offloaded Audio Processing, and note that audio hardware that is offload-capable replicates the architecture that is presented in the diagram shown in the topic. Sample capture MFX APO that implements Acoustic Echo Cancellation. Because channel data is removed, the APO negotiates an output format which is different than the input format. If it is interleaved the APO will strip out the loopback audio and deliver only the microphone audio upstream. Sample APO that uses KSPROPERTY_INTERLEAVEDAUDIO_FORMATINFORMATION to determine if the keyword spotter pin is interleaving loopback audio with the microphone audio and identify which channels contain loopback audio. Sample APO that adds a delay to the input samples. Sample APO that installs onto endpoints exposed by the SysVAD sample driver and swaps the left and right channels.

It also contains other common code shared by both sample drivers. DirectoryĮndpoints that are present in TabletAudioSample driver.Įndpoints that are present in both TabletAudioSample and PhoneAudioSample. The following table shows the features that are implemented in the various subdirectories of this sample.

In addition, this class contains common topology property handlers. The CMiniportTopologySYSVAD interface is the base class for all sample topologies. It also implements the IAdapterPowerManagement interface. The CAdapterCommon interface gives the miniports access to virtual mixer hardware.

The framework includes implementations of the following interfaces: The driver uses a "virtual audio device" instead of an actual hardware-based adapter, and highlights the different aspects of the audio offloading WDM audio driver architecture.ĭriver developers can use the framework in this sample to provide support for various audio devices without concern for hardware dependencies. The driver uses WaveRT and audio offloading for rendering devices. Some of these audio devices are embedded in the system (for example, speakers, microphone arrays) while others are pluggable (like headphones, Bluetooth headsets etc.). The Microsoft SysVAD Virtual Audio Device Driver (SYSVAD) shows how to develop a WDM audio driver that exposes support for multiple audio devices.

With the end of support for Windows 10 Mobile, the Phone Audio sample has been also removed from the SysVAD driver sample.
