In this tutorial, we will show you how to convert any audio file to mono for the use of Non-human Voice (NHV) feature in Voice Changer Software Diamond 9.

Non-human Voice (NHV) is a very interesting feature that can change your voice to various fabulous animal sounds when talking in real time. However, Voice Changer Software Diamond 9 can do much more than just changing voice to a bear, dog, birds or many other built-in animal voices. The software gives you the ability to add your own sounds such as your child’s crying, metal sounds and many more.To use your own audio sounds, NHV feature requires audio files with monochannel type.

Method #1: Convert any stereo file directly into mono type

This is a very simple way by using built-in Voice-overs Editor of Voice Changer Software Diamond to convert an audio file from stereo type into mono type.

  • Within the voice changing program main UI, explore Utilities and select to open Voice-Overs Editor.

After the file is converted, we can check again to make sure it is a mono file by loading the converted file in Voice-Overs Editor again. If you only see one channel just like the image below, the file can be used for NHV feature now.

Method #2: manually select which channel from the stereo file to use

A stereo file always contains 2 channels described as Left channel and Right channel. Usually, one of them sometime contains different audio data from the other one. The difference could be slightly or could also be largely.

So, in that case, we may want to select a single specific channel, which we believe it is better for the job, from the stereo file to save as a new mono type file.

  • Click on New file icon at the top-left of Voice-Overs Editor program to start a new blank audio file. Select any Sample Rate as your wish, but you must select Mono under Channels option.
