Virtual Audio Driver

Virtual sound card with SOUND4 processing engine at its core

What is Virtual Audio Driver Mode?

Virtual Audio Driver mode integrates processing engines with a WDM-compatible driver for input/output. After installation, new audio devices for input and output will appear in your Windows audio device list. Audio enters the processing core through the SOUND4 Virtual Audio Driver In, undergoes processing, and then exits via the SOUND4 Virtual Audio Driver Out.
