Auburn Sounds Graillon 3 vs OpenVoxTuner

Auburn Sounds Graillon 3 is a live vocal processor and pitch-correction plug-in for shaping standard or edgy vocals. Its pitch tools include pitch shifting, formant shifting, pitch correction, and three engines: G2, G3, and I1. A compressor, gate, chorus, preamp, and bitcrusher are built in; Auburn Sounds says the vocal-tuned effects add no latency. The free edition includes the pitch features and effects. The Full Edition adds Pitch-Tracking Modulation, keyboard tuning, a vocal doubler, and 20 more presets. Graillon supports CLAP, VST3, VST2, Audio Unit v2, AAX, LV2, and FLP formats on Windows 7 or newer, macOS 10.15 or newer, and Ubuntu 22.04 or newer. Listed host software includes Pro Tools, Cubase, Logic, Live, and FL Studio. The Full Edition costs $29.00 USD or more as a one-time purchase. The maker states there is no subscription or update fee. Session compatibility is maintained across minor version changes, but may break across major changes.

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.
