iZotope has released Vocal Doubler, a free plugin that is designed to add a natural doubling effect to your vocal tracks.
The user friendly effect adds rich tones and depth to your voice through an interactive visualization.
Vocal Doubler is perfect for placing directly on your vocal track and just adding a touch of space to make it stand out in the mix.
Using “Effect Only” mode, you can also create multiple doubled vocals on different tracks to further customize your sound.
The plugin is available for Windows and Mac and can be downloaded for free via the link below.
