01Overview

Vocal Harmonizer is built for producers who need harmony parts without recording and tuning multiple takes. From one vocal recording, it generates the extra voices itself, so there is no need to stack tracks or coordinate several singers. The developer says it produces full four-part harmonies instantly. Once the voices are generated, you can adjust EQ and panning to place the harmonic section in the mix, which helps the added parts sit with the lead vocal.

Generating Harmonies From a Single Vocal Track

Vocal Harmonizer works from one audio track of lead vocal. You can add a fifth below the melody, a major or minor third above it, or build a full background vocal section. AIR Music Technology says the plugin creates four-part harmonies instantly.

Because the harmony voices are generated by the plugin, timing and pitch alignment are handled for you. This is the main problem the developer highlights with stacking recorded vocal tracks or working with multiple background singers.

Mixing the Harmony Section

After the harmony voices are created, you can open the controls to adjust EQ and pan. This lets you shape the harmonic layer separately from the lead so it sits in the mix rather than competing with the main vocal.

Use the EQ and panning controls to position the added voices in the stereo field and balance them against the lead. The developer positions the plugin as a way to get professional-sounding vocal results while finishing tracks faster.
