You can connect Windows PC audio applications with Virtual Audio Cable (VAC), routing audio signals between them. You cannot relate Electric (analogue or digital) cables to traditional hardware audio devices (CD/LP player, FM receiver, equalizer tool, amplifier, etc.). VAC gives a set of virtual audio devices named Virtual Cables. To connect, you can select playback, recording endpoints, and destination applications. Without audio hardware, VAC performs signal transfer completely inside the PC. There is no quality loss, and no volume control is involved.

FULL NAME:Virtual Audio Cable

Source application produces digital audio signal via digital-to-analogue converter then through an electric cable, then analogue-to-digital converter, and lastly recorded by destination application. In case of connection, double digital-to-analogue and analogue-to-digital conversions are performed, and audio quality is degraded. Stereo Mix behaviour is similar to the VAC feature of hardware audio adapters. It would be best if you had functions such as “Stereo Mix” in Vista/Win7/8/10.

Key Features-

  • No audio hardware required– You don’t need either built-in or external audio hardware (sound adapter/card) for digital audio transfer. Audio hardware is necessary to record signals from external sources or to hear the results. Without an audio adapter (card) on PC, you can still use VAC to record audio signals produced by testing audio broadcast on a virtual server.
  • Control panel application– VAC enables you to change several Virtual Cables, cable settings, view VAC driver, and watch for cable/stream activity.
  • Device-to-device audio transfer– VAC devices helps you to organize application to application audio transfer only. Use the Audio Repeater application to perform endpoint to endpoint transfer. It’s included in the product package.
  • Driver-based solution– This driver needs to be installed with administrator norms. This driver is off the kernel-mode module. In windows, VAC represents the lowest- level audio layer being a WDM/KS filter. Any upper-level layer can successfully use it. For example: KS-aware applications, WASAPI and ASIO wrappers, and so on.
  • Comprehensive user manual -Free trial VAC user manual package is available on the download page. The manual details are useful for a better understanding of the product and for using it correctly. Read the user manual, and you don’t need to install the trial version to open. Download the ZIP archive and see the contents. Double click on the file by name “VAC.” You can recognize it by a question mark.
