The record

Purpose: OpenVoxTuner is a real-time vocal pitch correction and harmony generation plugin.
Auto correction: Auto mode uses scale quantization with 14 scale types and adjustable correction speed and amount.
Manual editing: Graphic mode lets users draw and edit pitch curves with snapping, grid, copy and paste, and undo and redo.
Harmony: The harmony engine supports up to four voices and offers voice and synthesized modes.
Key detection: Key detection can use audio input, the OpenVoxKey companion bridge, or a sidechain input.
Effects: Built-in effects include formant processing, reverb, a noise gate, and an upward compressor.
DAW integration: ARA2 integration reads key, scale, and time signature from the DAW timeline and syncs the playhead and waveform.
ARA2 limitation: The product page says OpenVoxTuner is a real-time effect and does not provide offline, note-level editing like dedicated pitch editors.
MIDI: The plugin supports MIDI note output generated from detected pitch and MIDI input to control correction pitch.
Platforms: The documentation lists Windows, macOS, and Linux builds, with plugin formats including VST3, CLAP, and AU depending on platform.
License: OpenVoxTuner is free for personal and commercial use under AGPLv3, with source code available on GitHub.
Privacy and transparency: The maker says the project is open source and has no telemetry or feature paywalls.
Support: The maker directs users to GitHub issues and discussions for support and accepts project sponsorships.
Intended users: The maker describes the free license as suitable for musicians, producers, studios, and educators.
