Description
iZotope Vocal Doubler is a dedicated vocal doubling plugin that adds natural-sounding width and depth to vocal recordings. It uses iZotope's acclaimed doubling algorithm to generate a convincing second voice from a single take, eliminating the need for manual double-tracking.
The interface centers on a single interactive control area where dragging vertically adjusts stereo separation and dragging horizontally controls human variation. This two-axis approach lets you dial in anything from subtle thickening to wide stereo spread in seconds.
Beyond vocals, producers regularly use Vocal Doubler on synths, guitar solos, and percussion to add stereo width and ensemble-like movement. The plugin runs with minimal CPU overhead, making it practical even in dense sessions with dozens of tracks.
Vocal Doubler supports all major DAW hosts including Logic Pro, Pro Tools, Ableton Live, Cubase, FL Studio, Studio One, and Reaper. It ships as a 64-bit plugin in AU, AAX, VST2, and VST3 formats for both macOS and Windows.
Users consistently praise its simplicity and sound quality, noting that it delivers results comparable to paid alternatives at a fraction of the setup time. The plugin has become a staple in vocal mixing templates across genres from pop and EDM to hip-hop and R&B.

Frequently Asked Questions
Can Vocal Doubler be used on instruments other than vocals?
Yes. Despite the name, Vocal Doubler works well on synths, guitars, percussion, and any mono source. Many producers use it as a quick stereo widener on lead instruments or to add ensemble-like thickness to drum loops.
How does Vocal Doubler compare to Soundtoys MicroShift or Waves Doubler?
Vocal Doubler focuses specifically on natural vocal doubling with a two-parameter interface, while MicroShift offers three hardware-modeled widening styles with more tonal control. Waves Doubler provides four voices with up to 100ms delay. Users often keep all three for different situations, with Vocal Doubler excelling at quick, transparent vocal doubles.
Does Vocal Doubler introduce latency or affect CPU performance?
The plugin is designed with minimal CPU overhead and introduces negligible latency. Multiple instances can run simultaneously in complex sessions without performance issues, making it practical for applying doubling to individual vocal tracks rather than using a single send.
Does Vocal Doubler work natively on Apple Silicon Macs?
Yes. The current version runs natively on Apple M-series chips as well as under Rosetta 2 on Intel Macs. It officially supports macOS Sonoma, Sequoia, and Tahoe.
