Virtual Audio Driver for Windows 10: A Comprehensive Guide

As a WDM/KS filter, Virtual Audio Cable (VAC) represents the lowest-level audio layer in Windows. This kernel-mode module requires administrator rights to install and provides a Windows WDM/KS virtual device driver that creates virtual audio devices.

One of the primary uses of VAC is to perform endpoint-to-endpoint transfer using the included Audio Repeater application. Virtual Cable devices, also known as endpoints, allow you to organize application-to-application audio transfer only.

The VAC Control Panel application offers a range of features, including the ability to change the number of Virtual Cables, view and modify VAC driver and cable settings, and monitor cable/stream activity. This flexibility makes it easy to customize your audio experience.

One of the most significant benefits of VAC is its ability to work without an audio adapter (card). You can still record audio signals produced by applications on a computer with no audio hardware, using the virtual devices created by VAC. Additionally, you don't need any audio hardware to use VAC for digital audio transfer.

While VAC provides a similar function to the 'Stereo Mix' feature found in some hardware audio adapters, it's important to note that this functionality comes at the cost of double digital-to-analog and analog-to-digital conversions, which can degrade audio quality. In contrast, VAC performs signal transfer completely inside the computer, without any audio hardware or quality loss (unless format conversion and/or volume control are involved).

With VAC, you can select playback and recording endpoints in source and destination applications to create a connection between them. This allows you to route audio signals between different applications, giving you greater control over your audio experience.

The 'Virtual Cable' term is used to describe the virtual devices created by VAC, which are actually just endpoints with unique names. Overall, VAC provides a powerful tool for connecting Windows PC audio applications together, making it easier than ever to route audio signals between different applications and enhance your overall audio experience.
