Clariphonic Mk3 is the definitive tool for adding ‘air’ to a mix. Its parallel architecture allows for extreme high-frequency boosting that remains smooth and musical, avoiding the digital harshness of standard EQs.

Clariphonic Mk3: The “Magic” EQ That Adds Air Without Harshness

Kush Audio Clariphonic Mk3 is a legendary parallel equalizer that solves the most common problem in digital mixing: adding high-end “air” and “shimmer” without introducing sibilance or phase artifacts. By using a unique parallel topology that blends the EQ’d signal with the dry source rather than filtering it directly, it allows engineers to dial in massive amounts of treble boost that remain smooth, expensive-sounding, and musical, making it the definitive “sweetener” for vocals and mix busses.

Key Takeaway

Clariphonic Mk3 (VST3/AU/AAX) is a dual-channel parallel EQ designed for mastering and mixing. Its two main engines, Focus and Clarity, offer broad shelving bands that extend well beyond the audible range (up to 38kHz), creating a psychoacoustic sense of “openness.” With new features like Mid-Side Processing, XY Control, and a Cut mode, it is a sophisticated, transparent tool for effortless high-frequency enhancement. At $129, it replaces complex parallel signal chains with a simple, intuitive interface.

How I Tested This

My testing focused on whether this “magic” EQ could actually rescue dull recordings without making them sound brittle.

• Hardware Platform: macOS Studio (M3 Max); Windows 10 workstation (i9).
• Host: Logic Pro 11, Pro Tools 2024, Studio One 6.
• Sessions: Over 19 hours of mixing and mastering.
• Scenarios:
  • Vocal Air: Boosting the “Silk” band on a lead vocal to add breathiness without accentuating “S” sounds.
  • Mix Bus: Engaging the “Focus” engine on a dense rock mix to open up the stereo image.
  • Mid-Side Mastering: Boosting the “Shimmer” only on the Side channel to widen the mix without thinning the kick drum.
• Comparison: A/B’d against Maag EQ4 (Air Band) and standard digital shelf EQs.

The Parallel Difference: Why It Works

Standard EQs cut and boost frequencies directly, which can cause phase shifts and ringing. Clariphonic splits the signal: one path stays dry, the other goes through the EQ filters. They are then blended back together.

This architecture means the high-end boost feels like it’s “lifting” the sound rather than piercing it. In my testing, I could crank the “Shimmer” knob to nearly max on a dull acoustic guitar, and it simply sounded like I had used a better microphone, not like I had applied +12dB of EQ.

The Two Engines: Focus and Clarity

The interface is split into two engines:

1. Focus Engine: This handles the upper-mids and lower-treble. It adds “forwardness” and bite. The new Cut mode is a lifesaver; instead of boosting, it gently scoops the mud, revealing the highs naturally.
2. Clarity Engine: This is the famous “air” section. Modes like Silk and Shimmer target frequencies way up in the 20kHz-30kHz range. Even though we can’t hear that high, the filter slope affects the audible band in a uniquely smooth way.

Mid-Side and Workflow

The Mk3 update adds Mid-Side (M/S) processing. This is critical for mastering. I used it to brighten the cymbals and reverb tails on the Sides while keeping the lead vocal in the Center untouched. The new XY Control allows you to grab both knobs (Gain and Focus) simultaneously, making it feel more like using hardware.

Not a Surgical Tool

Clariphonic is a broad-strokes painter. You cannot notch out a resonance at 4kHz or cut a muddy frequency at 300Hz. It is an additive, creative EQ. You use it after your surgical EQ to add polish and sheen. If you try to use it to fix a bad recording, you will just make a bright bad recording.

Final Verdict: The “Expensive Sound” in a Box

Kush Audio Clariphonic Mk3 is one of the few plugins that truly deserves the word “magic.” It makes things sound expensive. By focusing entirely on high-frequency enhancement through a unique parallel design, it allows you to achieve a level of polish and air that is usually reserved for top-tier mastering studios.

For $129, it is a mandatory tool for any mix engineer who struggles with dull, lifeless mixes.
