Virtual audio devices represent the filter graphs that render and capture audio content. The system audio driver (SysAudio) uses the available hardware and software components to determine the filter graphs to build.

For more information about the system audio driver, see SysAudio System Driver.

SysAudio's clients include DirectSound and the WDMAud system driver, which serves as the interface between WDM audio drivers and the audio-specific Microsoft Windows Multimedia APIs waveIn, waveOut, midiIn, midiOut, mixer, and aux (described in Microsoft Windows SDK documentation).

The KsStudio utility in the Windows Driver Kit (WDK) is an example of an application that bypasses SysAudio and allows users to construct filter graphs manually.

Spatial Sound Card is yet another free surround sound software for Windows. It is a really good surround sound software as it can optimize surround sound for both speakers and headphones. It can even simulate 5.1 surround sound effect in headphones. This software is created while considering games, movies, and music in mind. For all three cases. Once you uninstall the program download AnvSoft Video Converter from the AnvSoft website and install it on the PC. After installing the program you should be able to find the AnvSoft virtual sound driver on your PC.

Following PnP device enumeration, SysAudio takes stock of the registered audio hardware and software components in order to determine how to construct the various audio filter graphs that its clients might require.

After determining the list of filter graphs that it can build from the available hardware and software components, SysAudio registers these graphs as virtual audio devices for playback, recording, MIDI input/output, and mixing. SysAudio reserves the registry category KSCATEGORY_AUDIO_DEVICE exclusively for its virtual audio devices. Adapter drivers should not register themselves in this category.

A SysAudio client can treat a filter factory for a virtual audio device similarly to a filter factory for a hardware or software component. When asked by a client to instantiate a particular pin on a virtual device, SysAudio constructs the graph automatically and manages the graph's internal pin connections transparently to the client. This allows the client to treat a filter graph as a single filter, thereby avoiding complexities of graph management such as inter-filter communication.

• Mobile DJs will probably want to get all-in-one controllers, easy to transport and install anywhere.
• Resident DJs will probably want rackmount or table-top controllers (depending on the space available in the booth).
• Turntablists will want a TimeCode solution and a good sound card interface.
• Beginners will be more interested in all-in-one solutions.
