AutoTune Pro 11 vs OpenTune

AutoTune Pro 11 is a plugin for automatic and manual vocal pitch correction. Auto Mode applies real-time correction and includes formant and vibrato controls. Graph Mode supports detailed manual editing of pitch and time for vocal tuning. The Harmony Player provides four individual harmonies that can be mixed and triggered with MIDI, and Smart MIDI Mapping can assign a controller to any AutoTune Pro function. ARA2 support is listed for Logic, Studio One, Cubase and Nuendo. Other supported host integrations include Ableton Live, Cubase, FL Studio, Logic Pro X, Pro Tools and Studio One, with AU, VST3 and AAX formats depending on the host and operating system. Technical specifications list macOS 14 or higher and Windows 10 and 11. AutoTune Central installs and activates the plugins and is officially supported on macOS 11 or higher and Windows 10 and 11. A three-day trial is available. The perpetual license is described as a one-time payment to keep forever and includes a free month of AutoTune Unlimited; the subscription is billed monthly and can be canceled anytime. No price figure is listed for either plan.

OpenTune is a free, open-source vocal pitch correction tool for macOS and Windows. It regenerates vocals with a neural vocoder while preserving formants, and offers hand-drawing, note, and anchor tools for pitch editing. Automatic key detection supports Chromatic, Major, Minor, Pentatonic, Dorian, Mixolydian, and Harmonic Minor scales. Per-note EQ provides another way to adjust individual notes. The software imports WAV, FLAC, OGG, and MP3 audio and is available as a standalone executable or a VST3 plugin with ARA2 support. Its AI engine combines FCPE pitch extraction with a PC-NSF HifiGAN vocoder and ONNX Runtime inference. GPU acceleration uses DirectML on Windows and CoreML on macOS. The interface supports Chinese, English, Japanese, Russian, and Spanish. OpenTune is permanently free and licensed under AGPL V3.0. On macOS, release packages use ad-hoc signing without Apple notarization, so the first launch may show a developer verification prompt.
