Vocal Doubler
Vocal Doubler is a free VST audio plugin from iZotope that adds natural doubling and layering effects to vocal tracks. It uses iZotope's acclaimed doubling technology with an interactive interface to help producers create rich, dimensional vocal sounds by stacking additional voices from a single vocal source. The plugin is compatible with major digital audio workstations (DAWs) and runs as a VST component within the host application.
AI Recommendation
1 suggestionVocal Doubler has shipped with native Apple Silicon support since an earlier version — the iZotope release notes explicitly state that native arm64 support was added to the installer and Rosetta is no longer required. To get the native build, download and run the latest Vocal Doubler installer from iZotope's website (izotope.com/products/vocal-doubler). The installer will automatically detect your Mac's architecture and install the correct native component. If you use a DAW that manages plugins through its own plugin manager or a dedicated iZotope portal (such as iZotope Product Portal), you may also update Vocal Doubler through that channel — check your DAW's preferences or iZotope's support site for the specific steps. Since Vocal Doubler is a plugin component, not a standalone application, there is nothing to update in the App Store; the plugin update happens through the vendor installer or your DAW's plugin management system.
