iZotope VocalSynth

What is iZotope VocalSynth?

iZotope VocalSynth is a vocal synthesizer plug-in made by iZotope that transforms and synthesizes vocal recordings through modulation, harmony, and pitch manipulation tools. The plug-in combines traditional vocal effects with synthesis capabilities to enable producers and engineers to create new vocal textures, harmonies, and automated effects within a mixing or production workflow.

VocalSynth includes several core modules: a harmony generator that creates natural-sounding vocal layers, a vocoder for robotic and synthetic vocal effects, a compressor for dynamic control, and creative effects including distortion and filtering. The interface organizes these tools into intuitive, stackable processing chains. Users can control pitch independently from formant content, apply automatic pitch correction, and generate up to eight harmonies based on detected key and scale. The plug-in detects input melody and harmony automatically, reducing manual parameter adjustment. Presets come pre-configured for common production scenarios like doubled vocals, lo-fi effects, and harmonic stacking.

iZotope positions VocalSynth for mixing engineers, music producers, and songwriters working in DAWs like Ableton Live, Logic Pro, Pro Tools, and Studio One. The plug-in operates as a standard AU, VST, or AAX plug-in and integrates with iZotope's broader Music Production Suite, which includes mixing tools like Neutron and Ozone. VocalSynth is available as a standalone purchase or included within subscription plans. Users can access a free trial before committing to purchase.

The tool addresses vocal enhancement and creative synthesis needs, competing directly with software like Melodyne (Celemony), Auto-Tune (Antares), and Native Instruments Komplete's vocal modules. Production professionals often layer it alongside dedicated vocal mixing plugins for comprehensive vocal control.
