VB-Cable for Virtual Audio Cables

VB-Cable is probably the simplest way to set up a virtual audio cable between two applications.

The software is free and easy to download and install. It adds two virtual audio devices to your computer: CABLE Input (like a virtual microphone) and CABLE Output (like a virtual speaker).

The following is a typical use case.

• You have some program to add filters and tweaks to your microphone input, e.g. using OBS or specialized software.
• You prefer this processed audio and would like to use it elsewhere, say, a voice/video call software like Discord.

Using OBS+Discord as an example, these are the steps to accomplish the above.

• Set an audio monitor on the processed audio, and use CABLE Input as the monitoring device. That is, one end of the virtual cable is listening to your desired audio output. In OBS, this would be changing the monitoring device in the settings menu.
• Set the audio input as CABLE Output in the Discord. This is the other end of the virtual cable that outputs the same desired audio from the input end. In Discord, this would be changing the audio input device in the settings menu.

Visually, the setup looks like this: OBS --> CABLE Input --> VB-Cable Software --> CABLE Output --> Discord. The user only needs to configured the two ends.

Obviously, both ends of the virtual cable need to be up and running for the cable to work. For example, if OBS is shut down, Discord won't pick up anything from CABLE Output.
