What are the best virtual audio cable software tools?

Virtual Audio Cable

Virtual Audio Cable

Virtual Audio Cable is a software tool for Windows computers that does exactly what you’d expect it to do: acts as a virtual version of an audio cable and makes sure that the sound reaches its desired destination every time.

The behavior of this program is similar to the “Stereo Mix” feature of some hardware audio cards, better known as “What You Hear”. Virtual Audio Cable enables you to transfer up to 256 different audio signals between any applications simultaneously.

No audio hardware is required to use Virtual Audio Cable on your computer, but it becomes a necessity if you want to either hear the results or record signals from external sources.

This tool can be used on computers without audio cards to record audio signals that are generated by applications.



VB-Audio CABLE is a specialized software solution that can help you emulate a physical audio cable between apps on your computer by routing the audio signals generated by programs to any other app.

Since this tool acts as an audio driver, it should be very easy to decide the route of your audio signal by simply changing the input and output devices from within the apps you’re interested in connecting via sound.
