The new version of AV Voice Changer Software Diamond 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.

In this tutorial, we demonstrate how to use the Voice Changer Software Diamond 7.0 for changing your voice in Skype application.

- Make sure that the Timbre and Pitch (1) graph has been switched on for use.
- Because most instant messenger programs support Mono 8000Hz (3) only, we will need to set the output voice in VCSD to Mono mode for better quality.
- Move the cursor (2) around the graph to change Pitch and Timbre of the voice until you get the desired one.
- Reduce the Advanced tune (4) setting down to 0 (zero) for a better voice.

Now, just turn the Duplex on to pre-listen to your morphed voice and make any changes if necessary.

Open the VoIP program or any Voice Instant Messenger programs you want to use and dial the number.
As long as  AV Voice Changer Software Diamond is running and the Morphed feature is on, your voice will be morphed in real time.

- The current version of AV Voice Changer Software Diamond supports most voice chat and calling services of the common instant messenger programs.
