KERN Bundle
The deal
$55 at Plugin Boutique (down from $69), 20% off KERN Audio's full plugin bundle. This is an ongoing sale.
What it is
The KERN Bundle collects four mixing and mastering plugins from KERN Audio built around psychoacoustic frequency analysis. SMOOTH is a resonance suppressor that scans 40 ERB frequency bands to tame harsh peaks without dulling the mix. WARM adds tape, tube, and transformer-style saturation with adjustable harmonic character. WIDE expands stereo width while checking mono compatibility across the frequency spectrum, and PUSH is a multiband dynamics processor with three distinct modes (SETTLE, TIGHT, DRIFT). A free correlation meter, CHECK, is included for monitoring phase issues.
Who it's for
Mixing and mastering engineers who want precise, ear-friendly control over resonance, width, and harmonic saturation without stacking a dozen separate plugins to get there. It suits anyone finishing tracks in the box who needs mono-safe, phase-coherent processing on the way to a master.
Key features
- Uses 40 ERB psychoacoustic frequency bands for natural-sounding resonance control rather than generic EQ notching
- Every plugin includes real-time spectral visualization so you can see what's being processed
- Full M/S (mid-side) processing is supported throughout the bundle
- Each plugin runs under 3% CPU, and a single license key unlocks all four paid tools plus the free CHECK meter
