VoxDoubler

VoxDoubler is a vocal doubling plugin from Sonnox that addresses a persistent challenge in modern production: generating convincing vocal doubles without access to the original vocalist or the time-intensive process of manual pitch and timing manipulation. The plugin ships as two complementary tools designed for distinct doubling approaches.

The Widen module generates two additional mono voices panned left and right of the center vocal, ideal for opening up mono recordings or creating a stacked vocal aesthetic. Thicken operates differently, layering a new stereo doubled voice directly over the original performance to simulate the density achieved through multiple takes. Both employ sophisticated time-stretching and pitch-shifting algorithms that avoid the brittle, chorus-like artifacts common to generic harmonizer effects.

The core strength of VoxDoubler lies in its humanization controls. Rather than producing mechanically perfect duplicates, the plugin allows independent adjustment of timing and pitch deviation across generated voices, creating the natural micro-variations that characterize genuine multi-tracked performances. The depth slider provides control over how prominently the doubles sit in the mix, enabling anything from subtle enhancement to more dramatic widening effects.

VoxDoubler appeals primarily to mixing engineers and producers working with limited vocalist availability or budgets. It's particularly valuable in remote recording scenarios and for those seeking to preserve creative momentum during mixing without resorting to external editing software. While specialized doubling plugins exist at various price points, VoxDoubler's emphasis on naturalistic results and workflow efficiency positions it as a practical tool for professional work rather than a quick-fix effect, distinguishing it from conventional chorus or spatial processors.
