Auto-Tune ~$399 perpetual vs Melodyne Studio ~$699 perpetual
Best feature
Industry-standard real-time pitch correction with near-zero latency for tracking sessions
The catch
Real-time mode can introduce artifacts at extreme settings; style is limited to chromatic correction
Best feature
Polyphonic DNA technology allows per-note editing inside chords — unmatched in the market
The catch
No real-time mode; requires audio rendered to clip before editing begins
Use Auto-Tune for real-time vocal tracking and that signature effect; use Melodyne when surgical post-production accuracy is non-negotiable.
