The Feen
Class-A Mastering EQ
Three active bands per channel. Note-based frequency selection. Class-A Color circuit. High-pass filter. Dual-channel processing with L/R Link. A/B comparison.
Feature Set
Note-Based Frequency Selection
12-note chromatic selector on every EQ band. Choose the note, choose the octave. Every octave available. The plugin calculates the exact hertz value.
+1 STEP
Reach between-note frequencies without leaving the musical grid. STEP is always independent of L/R Link — create stereo harmonic complexity while keeping your EQ decisions coupled.
Class-A Color Circuit
Analog harmonic saturation, selectable per band or full-range. Ten-step amount control. 2× oversampling in Full mode for clean high-end while harmonics do their work.
High-Pass Filter
Dedicated HPF with adjustable cutoff. 12 dB/oct slope. Independent per channel when L/R Link is off.
Three Active Bands Per Channel
Low, mid, high — each with note selector, gain, bandwidth, and Bell/Shelf mode. Gain range ±12 dB. Bandwidth 0.1 to 4.0 octaves.
Dual-Channel Processing
L/R Link for fast stereo work. Fully independent per-channel control when you need surgical precision. All parameters available on both channels.
A/B Snapshot Compare
Store two complete plugin states. Switch instantly. Trust the comparison your ears make, not your memory.
Standalone App
Runs without a DAW. Useful for a dedicated mastering workflow where you want the EQ session to live outside your project.
