What is VAC?

VAC is a software suite which includes an Audio Repeater, and Control Panel.

1. VAC Control Panel

VAC Control Panel allows for the creation of Virtual Audio devices (Cables) or VACs. VACs are created in pairs; one Line-In (input, capture) and Line-Out (output, render). Many VAC pairs may be created.

2. VAC Audio Repeater

VAC Audio Repeater is a useful tool which allows for an audio stream to passthrough between two devices (cables). By default, Windows will allow for up to one output cable to "listen" to one input, equivalent to an "audio repeater". VAC Audio Repeater allows for many more of these to exist.

Why?

1. Mirror Audio Sources

By default, Windows allows for a Video source to be mirrored across multiple displays. VAC Manager aims to do the same, but for Audio and with a nice user interface.

2. Multiplexing

Want to broadcast video game audio and voice chat together to your headphones, but on separate lines for game session recording or streaming? You can do that.

Or you want to play music directly to your voice chat, by a virtual microphone? You can do that, too.

These examples are known as multiplexing.
