VB-Audio Virtual Cable Driver
Virtual Audio Cable (VAC) is a driver-based utility that creates virtual audio devices inside Windows. It enables audio data to flow from a source application to a destination application through software endpoints, effectively acting as a non-physical audio cable. This is essential for livestreaming, podcasting, and complex audio routing workflows where multiple programs need to share audio streams without external hardware.
VAC installs a kernel-mode driver and a user-space control interface that expose virtual input and output endpoints. Applications select these endpoints as their audio devices, and the driver passes PCM data between them in real time, with configurable sample rates and channel counts to suit recording and mixing tasks.
Virtual Audio Cable is a legitimate driver-based tool widely used by content creators and audio professionals to route audio between applications. When downloaded from official VB-Audio sources, installed with administrator privileges, and kept up to date, VAC operates within the Windows audio stack as a controlled virtual device. Like any driver-based software, it should be treated with standard security practices: verify publisher, use reputable installers, and avoid untrusted copies. Regular updates from the official site reduce risk of misconfiguration or driver conflicts that could impact stability.
The VAC executable itself is not a virus when obtained from verified sources and used as intended. However, malicious actors may rename executables or host counterfeit installers to mimic VAC, potentially delivering malware. If you encounter an unexpected file named virtual-audio-cable.exe in a non-official folder, or experience unusual system behavior, treat it as suspicious and perform verification steps. Always confirm publisher, digital signature, file path, and hash before trusting the file.
Red Flags: Unexpected install locations (temp or user downloads), unsigned or mismatched signatures, multiple copies in non-standard folders, or a copy of virtual-audio-cable.exe that appears alongside unrelated software are warning signs to investigate further.
Reasons it's running:
virtual-audio-cable-exe is the executable component of VB-Audio Virtual Cable that powers the virtual audio endpoints. It enables software-based routing of audio between applications, acting as a bridge for input and output channels without needing physical cables.
Yes, VAC is typically safe when downloaded from the official VB-Audio site and installed from trusted installers. It installs a kernel driver and virtual devices; always keep it updated and verify signatures to minimize risk.
Run the VAC installer again and select Uninstall, or use Windows Settings > Apps > VB-Audio Virtual Cable to remove it. A reboot may be required to complete the removal and clean up drivers.
Yes. By routing the system output to a VAC input and selecting the VAC output in the recording software, you can capture game or system audio without hardware cables.
VAC provides 64-bit compatible drivers where available, allowing 64-bit applications to route audio through the virtual endpoints. Check the official site for the latest build notes.
During installation, VAC may expose separate input and output devices for different sample rates or channels. This is normal; select the specific pair needed for your workflow and disable unused ones to reduce confusion.
