EQOMP

Threshold-Curve-Driven Dynamic EQ

A revolutionary approach to frequency-selective dynamics processing where the EQ curve itself defines the reduction threshold.

Introduction

EQOMP (EQ + Compressor) is a professional dynamic equalizer that introduces a fundamentally new approach to frequency-selective dynamics processing. Unlike traditional multiband compressors or dynamic EQs, EQOMP uses the EQ's frequency response curve as the compression threshold itself.

The Core Innovation

In EQOMP, the threshold is not a horizontal line — it's a curve that follows the exact shape of your EQ band's frequency response. This creates musical, transparent dynamics processing that respects the natural harmonic structure of your audio.

🎯

Precision Targeting

Apply dynamics processing with surgical precision using parametric EQ-style frequency selection.

🌊

Continuous Response

Core Concept

The Threshold Curve Paradigm

Traditional compressors use a single threshold value — a horizontal line at a fixed dB level. When the signal exceeds this line, overall level reduction occurs. Traditional compressors adjust the overall output level within a fixed time period. This works well for overall dynamics control, but lacks frequency selectivity.

EQOMP introduces the Threshold Curve concept: instead of a flat line, the threshold follows the shape of your EQ band. So the center frequency is most sensitive, and the effect tapers off toward the edges of the band — just like your EQ curve.

Why This Matters

This approach solves several fundamental problems with traditional frequency-selective dynamics:

No Crossover Artifacts

Unlike multiband compressors, there are no crossover filters splitting the signal. The audio path remains intact.

Harmonic Preservation

Because processing follows the natural EQ curve, harmonics above and below the fundamental are treated proportionally.

Intuitive Control

If you know how to use a parametric EQ, you already know how to target frequencies in EQOMP.

What Makes EQOMP Different

Comparison with Traditional Tools

Feature Multiband Comp Dynamic EQ EQOMP
Frequency Selection Fixed crossovers Parametric bands Parametric bands
Threshold Shape Flat per band Flat per band Follows EQ curve
Phase Coherence Crossover issues Maintained Maintained
Harmonic Treatment Band-limited Partial Proportional
Processing Method Split → Process → Sum Gain modulation Curve-weighted reduction
Transparency Moderate High Very High
CPU Efficiency Good Good Excellent

In Short

Threshold follows your EQ curve — so the band you set is the band that gets dynamics. Q sets how wide that area is (narrow = surgical, wide = gentle). No splitting the signal like multiband compressors; you get transparent, musical control. Think of Ratio as “how much to turn down” when the level exceeds the threshold, not classic compression.

Global Controls

Input/Output Gain

INPUT
-30 to +30 dB
Adjusts the level entering the processing chain. Use to drive into the threshold or reduce input level.
OUTPUT
-30 to +30 dB
Final output level adjustment. Use for gain staging and matching bypassed level.

Bypass

The global BYPASS button operates in the same way as normal mode, but audio passes through unchanged and "BYPASS" text appears in the waveform display. When bypassed:

License Note

Without a valid license, EQOMP operates in bypass mode. In this case, the BYPASS button is disabled to prevent accidental processing. Activate your license to unlock full functionality.

Bypass Mode (UNITY / GAIN)

Bypass affects only the signal path — whether the output is passed through (bypassed) or processed. It has no effect on GUI or DSP operation; meters and displays continue to work.

Select UNITY when you want to hear the dry signal; select GAIN when you want the full processed signal. The setting is available in the Utility panel (BYPASS MODE).

Oversampling

1x
Native
No oversampling. Lowest CPU usage. Suitable for most applications.
2x
2× sample rate
Moderate oversampling. Good balance of quality and CPU.
4x
4× sample rate
High quality. Recommended for final mixing.
8x
8× sample rate
Maximum quality. Use for mastering or critical applications.

Right Panel Slider

The right panel contains a vertical slider located to the left of the output meters. This slider provides powerful global control over EQ curves and threshold settings with four different modes.

Drag (No modifier)
EQ Level Mode
Adjusts the gain of all active bands by the same amount. Dragging up increases gain, dragging down decreases gain. This is useful for overall EQ curve level adjustments while maintaining the relative shape.
Option + Drag
EQ Tilt Mode
Applies a frequency-dependent tilt to all active bands, centered at 1 kHz. Dragging up (right) creates a counter-clockwise tilt (boosts low frequencies, cuts high frequencies). Dragging down (left) creates a clockwise tilt (cuts low frequencies, boosts high frequencies). The effect is proportional to the logarithmic distance from 1 kHz — bands closer to 1 kHz change less, while extreme frequencies (20 Hz, 20 kHz) change more. The existing EQ curve shape is preserved while the tilt is applied.
Command + Drag (Mac: Cmd, Windows: Ctrl)
Threshold Level Mode
Adjusts the threshold of all active, non-bypassed bands by the same amount. Dragging up increases threshold (less compression), dragging down decreases threshold (more compression). This is useful for overall threshold adjustments while maintaining relative threshold relationships.
Command + Shift + Drag (Mac: Cmd+Shift, Windows: Ctrl+Shift)
Threshold Tilt Mode
Applies a frequency-dependent tilt to all active, non-bypassed band thresholds, centered at 1 kHz. Dragging up (right) creates a counter-clockwise tilt (increases low-frequency thresholds, decreases high-frequency thresholds). Dragging down (left) creates a clockwise tilt (decreases low-frequency thresholds, increases high-frequency thresholds). The effect is proportional to the logarithmic distance from 1 kHz. This allows for frequency-selective compression sensitivity adjustments.

Visual Feedback

When dragging either slider, the current mode (LEVEL or TILT) is displayed next to the slider handle. The threshold slider shows both the control type (EQ or THRESHOLD) and the mode (LEVEL or TILT) in two lines. The slider handles return to the center position (0 dB) when released, but the parameter changes remain applied.

EQ Parameters

MODE
5 types
Filter type selection:
  • Parametric — Bell/Peak filter with adjustable Q
  • Shelf-Hi — High shelf filter
  • Shelf-Lo — Low shelf filter
  • Filter-Hi — High-pass filter
  • Filter-Lo — Low-pass filter
FREQUENCY
20 Hz - 20 kHz
Center frequency (Parametric) or corner frequency (Shelf/Filter). Logarithmic scaling for musical control.
GAIN
-20 to +20 dB
Static EQ gain. This is the "resting" gain when no dynamics processing is occurring. Not available for Filter modes.
Q
0.1 to 10
Bandwidth:
  • Low Q (0.1-0.5) — Wide, gentle curves
  • Medium Q (0.5-2) — Musical, versatile
  • High Q (2-10) — Narrow, surgical
In Parametric mode, Q also defines the dynamics processing width.

Dynamic Parameters

THRESHOLD
0 to -60 dBFS
Sets the sensitivity of dynamics processing at the center frequency. Remember: this becomes a curve, not a line. At 0 dBFS, no processing occurs. Lower values = more sensitive.
RATIO
1:1 to 20:1
Controls the amount of gain reduction applied when signal exceeds threshold:
  • 1:1 — No reduction (dynamics off)
  • 2:1 to 4:1 — Gentle, transparent control
  • 4:1 to 8:1 — Moderate compression feel
  • 8:1+ — Strong limiting behavior
Note: This is reduction ratio, not compression ratio. There's no actual compression curve.
ATTACK
0.1 to 100 ms
How quickly gain reduction responds to transients:
  • Fast (0.1-5 ms) — Catches transients, may reduce punch
  • Medium (5-20 ms) — Balanced, preserves some attack
  • Slow (20-100 ms) — Lets transients through, smooth response
RELEASE
10 to 1000 ms
How quickly gain returns to normal after signal drops below threshold:
  • Fast (10-50 ms) — Quick recovery, may pump
  • Medium (50-200 ms) — Natural, musical
  • Slow (200-1000 ms) — Smooth, sustained reduction

Dynamics Enable

Each band's dynamics processing can be independently enabled/disabled. When disabled, the band functions as a static EQ only. Enable dynamics to activate the threshold-curve processing.

Filter Modes

Parametric (Bell/Peak)

The default and most versatile mode. Creates a bell-shaped curve centered at the frequency with width determined by Q.

  • Dynamics behavior: Gain reduction follows the Q curve exactly
  • Best for: Surgical frequency control, resonance taming, tone shaping

Shelf-Hi (High Shelf)

Boosts or cuts all frequencies above the corner frequency.

  • Dynamics behavior: Processing applies to all frequencies above the corner
  • Best for: Air/brightness control, high-frequency taming

Shelf-Lo (Low Shelf)

Boosts or cuts all frequencies below the corner frequency.

  • Dynamics behavior: Processing applies to all frequencies below the corner
  • Best for: Bass control, low-end management, warmth adjustment

Filter-Hi (High-Pass)

Removes frequencies below the cutoff. No gain parameter — only filtering.

  • Dynamics behavior: Dynamic high-pass filtering based on input level
  • Best for: Dynamic rumble removal, bass cleanup that responds to content

Filter-Lo (Low-Pass)

Removes frequencies above the cutoff. No gain parameter — only filtering.

  • Dynamics behavior: Dynamic low-pass filtering based on input level
  • Best for: Dynamic harshness control, adaptive brightness limiting

Compressor Control in Filter/Shelf Modes

Important: When a band is changed to Filter or Shelf mode, the compressor is controlled per band, not per bandwidth. Unlike Parametric mode where compression follows the Q curve (bandwidth), Filter and Shelf modes apply compression to the entire frequency range above or below the corner frequency, making the compressor operate on a band-by-band basis rather than following a bandwidth curve.

Use Cases

De-essing (Vocal Sibilance Control)

Setup

  • Mode: Parametric
  • Frequency: 5-8 kHz (find the sibilant frequency)
  • Q: 2-4 (narrow enough to target sibilance)
  • Gain: 0 dB (no static EQ)
  • Threshold: -20 to -30 dB
  • Ratio: 4:1 to 8:1
  • Attack: 0.5-2 ms (fast to catch sibilants)
  • Release: 50-100 ms

Why EQOMP excels: The threshold curve means only the sibilant frequencies trigger reduction, and the reduction is proportional to the frequency content — not a blanket cut.

Bass Resonance Taming

Setup

  • Mode: Parametric
  • Frequency: Find the resonant frequency (often 80-200 Hz)
  • Q: 4-8 (narrow to target the resonance)
  • Gain: 0 dB
  • Threshold: -15 to -25 dB
  • Ratio: 3:1 to 6:1
  • Attack: 10-30 ms
  • Release: 100-200 ms

Why EQOMP excels: Tames only the resonant frequency when it becomes excessive, leaving the rest of the bass intact.

Dynamic Air Enhancement

Setup

  • Mode: Shelf-Hi
  • Frequency: 8-12 kHz
  • Gain: +2 to +4 dB (static boost)
  • Threshold: -25 to -35 dB
  • Ratio: 2:1 to 3:1 (gentle)
  • Attack: 20-50 ms
  • Release: 200-400 ms

Result: High frequencies are boosted, but excessive brightness is automatically controlled. You get air without harshness.

Drum Transient Shaping

Setup

  • Mode: Parametric
  • Frequency: 2-5 kHz (attack frequencies)
  • Q: 1-2 (moderate width)
  • Gain: 0 dB
  • Threshold: -20 to -30 dB
  • Ratio: 2:1 to 4:1
  • Attack: 30-50 ms (let transients through)
  • Release: 50-100 ms

Result: The attack of drums punches through while the sustain/ring is controlled in the target frequency range.

Mastering — Gentle Frequency Balance

Setup

  • Multiple bands with very gentle settings
  • Q: 0.5-1 (wide, gentle curves)
  • Threshold: -30 to -40 dB
  • Ratio: 1.5:1 to 2:1 (very gentle)
  • Attack: 20-50 ms
  • Release: 200-500 ms

Result: Transparent frequency balance that responds to the music. Problem frequencies are gently controlled without obvious processing. For mastering applications, you can use the Single Band or Multiband presets for more effective frequency control. Tip: It's recommended to use single-band compressors that apply different gain reduction for different frequencies, rather than uniform gain reduction across all frequencies.

Frequency-Selective Reduction

Concept

With EQOMP, each band reacts only in its own frequency range. A loud snare won’t pull down the whole bass or piano — only the frequencies that overlap. So you can tame problem peaks without changing the rest of the mix.

Setup

  • Mode: Parametric or Multiband
  • Use multiple bands for different frequency ranges
  • Set thresholds per band independently
  • Ratio: 2:1-6:1
  • Attack/Release: Adjust per instrument characteristics

Result: Each band is independent. You control only the frequencies that need it; the rest stays natural.

Unwanted Resonance Reduction

Concept

You can reduce the level of unwanted resonances outside of the essential resonances of the audio source by adjusting the attack time. A huge advantage is that you can use a multiband compressor without worrying about phase.

Setup

  • Mode: Parametric
  • Frequency: Target the unwanted resonance
  • Q: 4-10 (precise targeting)
  • Threshold: -15 to -30 dB
  • Attack: 0.5-5 ms (fast reduction)
  • Ratio: 3:1-8:1

Result: Unwanted resonances are quickly reduced while preserving the essential character of the source. The phase-coherent processing ensures transparent results.

Bus Compressor / Master Bus / Glue Compressor Applications

Concept

Use several bands with wide Q and gentle ratios to add glue and cohesion. Each band reacts to its own range, so you can gently control the low end while keeping mids and highs punchy — or the opposite.

Setup

  • Start with Single Band or Multiband presets to configure your bands
  • Set up multiple bands across the frequency spectrum
  • Each band can control up to half the maximum buffer size in frequency range
  • Adjust thresholds, ratios, attack, and release per band independently
  • Use gentle ratios (1.5:1 to 3:1) for glue compression
  • Moderate attack (20-50 ms) and release (100-300 ms) for musical timing

Result: Cohesive bus or master compression with independent control per frequency range, so the mix gels without losing punch or clarity.

Pro Tips

1. Start with Dynamics Off

Set up your EQ curve first with dynamics disabled. Get the static tone right, then enable dynamics to control problem areas. This gives you a clear reference point.

2. Use the Gain Reduction Meters

Watch the vertical GR lines on each band. If you're seeing constant reduction, your threshold may be too low. Aim for reduction only on problem moments.

3. Q Affects Dynamics Width

Remember: in Parametric mode, Q doesn't just shape the EQ — it defines how wide the dynamics processing applies. A narrow Q means surgical dynamics; a wide Q means broader control.

4. Ratio is Reduction, Not Compression

EQOMP's ratio controls gain reduction, not compression ratio. There's no knee or compression curve. Think of it as "how much to turn down when triggered."

5. Use A/B Comparison

EQOMP's processing is designed to be transparent. Use A/B comparison frequently to ensure you're improving the sound, not just making it different.

6. Oversampling for Critical Work

For mastering or final mixes, enable 4x or 8x oversampling. The CPU hit is worth it for the cleanest possible processing.

7. Shelf/Filter Modes for Broadband Control

When you need to control entire frequency ranges (all highs, all lows), use Shelf or Filter modes. The dynamics will apply to the entire range, not just a bell-shaped area.

8. Avoiding Artifacts from Aggressive Settings

High ratio, low threshold, and very fast attack together can cause harshness or pumping. Ease off ratio, attack, or threshold until it sounds natural. The goal is processing that improves the sound without calling attention to itself.

9. Understanding Compressor Noise

Excessive compressor processing inevitably introduces noise. This occurs because gain reduction operates as a time-varying control signal that modulates the audio itself. This compressor is designed to minimize such modulation, preserving natural sound even under heavy reduction.

10. AM Noise Control: The Foundation of Professional Dynamic EQ

AM (Amplitude Modulation) noise occurs when the gain envelope changes faster than the audio waveform, causing phase distortion and harsh artifacts. EQOMP prevents this by keeping the gain envelope slow and smooth (sub-audio, below 10Hz), even with fast attack settings. Detection can be fast, but gain application must always be slow and musical.

In summary: EQOMP calculates dynamics based on frequency, but always applies gain as a smooth, time-domain envelope. This prevents AM noise from rapid gain reduction while maintaining natural phase and harmonic relationships.

11. Master Bus / Mastering Presets: Full-Range Control via Band 1

Master Bus Comp and Mastering presets are bandwise band compressors that control the full frequency range. After loading one of these presets, adjust the threshold of Band 1 (the lowest band) to control the entire frequency range with a single parameter — a quick way to set overall dynamics.

Global Settings

These settings apply globally across all plugin instances and are saved between sessions.

When to use: 1x for tracking and low latency. 2x–4x for mixing. 8x for mastering or when using heavy reduction and high Q. If you hear harshness or artifacts, try raising oversampling.
