e2eSoft VAudio is a virtual audio driver software for Windows that enables the routing and recording of audio from different applications. It's often used for capturing and mixing audio from different sources, such as online streaming, games, or music apps, and then redirecting or recording that audio. Essentially, it creates a virtual audio device that acts as a bridge between your applications and other software, allowing you to manipulate and record the audio.

e2eSoft VAudio works:

1. It installs a virtual audio driver on your system that behaves like a physical sound device.
2. You can use this virtual device to capture and redirect audio streams from various software applications.
3. You can set the virtual device as the input/output in your audio recording or mixing software, or route the audio to external applications like OBS (Open Broadcaster Software), Skype, or other communication platforms.
