OpenVoxTuner vs Performative Ear

OpenVoxTuner is a free real-time vocal pitch correction and harmony-generation plugin for Linux, macOS, and Windows. Its Auto mode quantizes pitch to one of 14 scale types, with adjustable correction speed and amount. Graphic mode provides pitch-curve editing with snapping, a grid, copy and paste, and undo and redo. The harmony engine supports up to four voices, in voice and synthesized modes. Key detection can use audio input, the OpenVoxKey companion bridge, or a sidechain input. Built-in effects include formant processing, reverb, a noise gate, and an upward compressor. ARA2 integration reads key, scale, and time signature from the DAW timeline and syncs the playhead and waveform, but the plugin remains a real-time effect rather than an offline note-level editor. MIDI output can be generated from detected pitch, and MIDI input can control correction pitch. The plugin is free for personal and commercial use under AGPLv3, with source code on GitHub. The maker says it has no telemetry or feature paywalls and directs support questions to GitHub issues and discussions.

Performative Ear is a paid pitch-correction plug-in designed for low-latency singing on Windows and macOS. Performative Ear listens to a song and sends its detected key to the pitch-correction plug-in automatically, while passing audio through unchanged without files or network use. Four correction modes are listed: Live at 1.3 ms, Crisp at 18 ms, Voice at 25 ms, and Full at 40 ms. Users can choose chromatic, major, or minor scales and toggle notes to create a custom scale. The maker lists tested support for Ableton Live 11 and 12, Cubase, FL Studio, Fender Studio Pro, Bitwig Studio, REAPER, Audacity, and GarageBand. Formats include VST3 and CLAP on Windows x64 and macOS Universal, plus Audio Unit on macOS. The price is $199 as a one-time purchase, with no free plan and a free Windows demo. One license supports three active machines.
