Your operating system sees this as a speaker. You can configure any application (like Google Chrome or a video game) to send its sound to this "speaker." virtual audio cable
Virtual Audio Cable is a software-based audio driver that creates virtual audio devices on your computer. Think of it as an invisible wire that routes audio signals directly from one application to another. Where you would typically need physical cables to connect a synthesizer to a mixer, VAC achieves the same connection digitally, sending pristine audio from a media player to a recording app without a single physical cord.
The setup process is generally the same regardless of which software you choose: The magic of VAC becomes clear when applied
If using a mixer like Voicemeeter, increase the buffer size (latencies) in the settings menu to give your CPU more time to process the digital audio. The "No Sound" Issue
⚠️ Windows may show a driver signature warning — you’ll need to allow unsigned drivers or disable signature enforcement temporarily. If you share with third parties, their policies apply
There are a few big names in this space, ranging from simple "one-wire" fixes to complex digital mixers.
Developers who work with audio processing libraries, speech recognition, or text‑to‑speech systems can use VAC to create automated test environments. They can generate synthetic audio in one program, route it through a virtual cable, and capture it in another program for analysis—all without physical hardware.
