Description

Enhance vocal depth and presence with the Sonnox VoxDoubler, a specialized tool designed to add rich, natural-sounding vocal doubles to your tracks. Perfect for creating wider, fuller vocals, the VoxDoubler offers both Widen and Thicken modes, allowing you to either expand the stereo image or add a layered, thickened vocal effect for added texture and impact. Whether you’re crafting subtle vocal layers or bold, upfront doubles, this plugin provides flexibility for any genre or production style.

The Sonnox VoxDoubler integrates seamlessly with your DAW and boasts an intuitive interface, making it easy to dial in the right amount of doubling effect without overpowering the original signal. With built-in pitch and timing controls, you can adjust each layer for a truly organic, natural sound, eliminating the need for multiple takes or extensive editing.

No more painstaking hours spent layering multiple takes. With VoxDoubler, doubling your vocals is effortless. Whether you want to add punch to your leads or spread your backing vocals across the stereo field, VoxDoubler delivers pro-quality results fast.

    Widen Your Backing Vocals

Add VoxDoubler to Your FX Chain

Why stop at vocals? Place VoxDoubler before your reverb to achieve haunting, spacey effects with endless depth, or add it before a delay for tape-like delays with subtle, evolving variations.


Not Just for Vocals

Double a brass or string instrument and watch VoxDoubler turn a solo into an entire ensemble. Whether you’re scoring for film or creating a bigger-than-life band arrangement, this tool adds richness and fullness to any instrument.

If you’re looking for a utility stereo-izer effect to use for various elements in your mix, VoxD Widen works great as a send/return effect and it’s worth the money alone for that. Produce Like A Pro
