Our verdict on Tunix

Tunix combines low-latency vocal pitch correction with a scale-aware harmonizer for macOS. It is aimed at singers, producers and other vocal-focused creators who want corrected pitch and arranged harmonies in one tool. Automatic key detection and selectable scales provide a starting point, while MIDI and chord-following modes let harmony track musical input. The product is available in AU and VST3 formats, as well as standalone, so it can fit different macOS workflows without requiring a host for standalone use.

The harmony section is the clearest point of distinction. Tunix provides three voices, with individual controls for interval, level, pan, formant, detune, vibrato and Humanize. Formant preservation and throat shaping support changes to vocal character, while the correction engine is described as PSOLA-based and low-latency. For users who want more than fixed intervals, the choice between scale-aware, MIDI and chord-following modes gives the harmonies different ways to follow a song. The three-voice ceiling makes it a focused tool rather than a solution for larger vocal arrangements.

Beyond pitch and harmony, Tunix includes doubling, dual-LFO modulation, stereo widening, de-essing and output mixing controls. Ducking reverb and delay wash, plus a tempo-synced rise, add effects-oriented options within the same product. Tunix is sold as a one-time purchase and has no free plan, so it suits buyers looking for a dedicated macOS vocal plug-in rather than a free option or a cross-platform tool. Mac-based creators seeking low-latency correction and controllable harmonies have a compact set of vocal features here; users on other operating systems or needing more than three harmony voices should look elsewhere.
