The new version 7.0 of AV Voice Changer Software has a Virtual Audio Driver (AVnex Virtual Audio Device) which works as a virtual audio & sound device. This device can be used with any VoIP, Instant Messenging applications, or online voice chatting or web conferencing websites for changing voice and/or recording in real-time. By setting AVnex Virtual Audio Device as default audio driver for microphone in those applications, you will be able to control your voice tone and speak the way you want.

In this tutorial, we will guide you through the way to set up Voice Changer Software 7.0 (VCS7) to automatically change voice for online voice communication on Callcentric.
