The new version 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 application and Instant messengers for changing voice and/or recording in real-time. By setting AVnex Virtual Audio Device as the active audio driver for the microphone in those applications, you will be able to control your voice tone and speak the way you want.
