Harmonic EQ: Free Pitch Tracking EQ Plugin by Aeons Light
Aeons Light has released Harmonic EQ, an intelligent pitch-tracking equalizer plugin available as an unconstrained free download with no trial expiration. The plugin detects incoming pitch or accepts MIDI control to modulate eight filter bands across fundamental and harmonic frequencies in real time. Producers can grab the installer directly from the developer without account creation or email registration.
Pitch-Tracking Equalization and Harmonic Control
Harmonic EQ simplifies cleaning or sculpting resonant frequencies in monophonic material like vocals, 808s, lead synths, and bass lines. Rather than drawing complex frequency automation over changing notes, the equalizer follows performance pitch swings automatically.
Key features include:
- 8 independent filter bands supporting bell, shelf, notch, high-pass, and low-pass curves
- Pitch detection driven by audio analysis, direct MIDI input, or external sidechain routing
- Dynamic mode with per-band threshold controls and real-time spectrum analysis
- Band soloing to isolate overtones, partials, and unwanted resonances
- 75 factory presets tailored for vocal clarity, bass tightening, and instrument tone shaping
- Broad cross-platform support across Windows, macOS (Intel & Apple Silicon), and Linux
Free Version vs Lifetime License
Unlike traditional evaluation software, the free edition of Harmonic EQ provides unrestricted audio functionality. There are no intermittent audio dropouts, periodic bursts of noise, or disabled preset save features. The only difference between tiers is a brief countdown splash screen shown when loading the plugin.
Users who wish to remove the launch countdown can purchase a lifetime license for $25 to $50, but the developer has committed to keeping the free version indefinitely usable with zero functional compromises.
You can download Harmonic EQ directly from Aeons Light.
Harmonic EQ provides complete harmonic and dynamic equalization for Windows, macOS, and Linux systems in VST3, AU, and CLAP formats. The free download remains fully functional without an expiration date or software registration requirements.
