AI Harmonizer

BandLab's AI Harmonizer is a one-tap tool that generates natural-sounding vocal harmonies from your existing recordings. Add instant depth, richness, and professional polish to your vocals, saving you from manual pitch editing, duplicating tracks, or recording extra layers from scratch.

Designed for beginners and seasoned producers alike, AI Harmonizer removes the music theory guesswork from vocal arrangement so you can stay in your creative flow.

Note: AI Harmonizer is available on Web and Mobile exclusively with a BandLab Max Membership
