Here’s a comprehensive EQ Guide for Mixing — a full-text reference covering the fundamentals, practical techniques, frequency ranges, and genre-specific tips.
The Complete EQ Guide for Mixing Introduction EQ (Equalization) is the most fundamental mixing tool. It shapes the tonal balance of individual tracks and the overall mix by boosting or cutting specific frequency ranges. Proper EQ creates clarity, separation, depth, and prevents frequency masking.
1. EQ Fundamentals What is EQ? An EQ adjusts the level (gain) of selected frequency bands. Think of it as a tone control that can target bass, mids, or treble. Common EQ Parameters
Frequency (Hz/kHz): Which part of the spectrum you're affecting. Gain (dB): How much you boost or cut. Q (Bandwidth): How wide or narrow the affected frequency range is. High Q = narrow notch; Low Q = wide shelf. Filter Types: eq guide for mixing
Low Cut / High‑Pass Filter (HPF): Cuts frequencies below a set point. High Cut / Low‑Pass Filter (LPF): Cuts frequencies above a set point. Bell/Peak: Boosts/cuts a specific range (adjustable Q). Shelving: Boosts/cuts all frequencies above or below a set point. Notch: Extremely narrow cut to remove a single problematic frequency.
Types of EQs
Parametric: Full control over frequency, gain, Q. Most versatile. Graphic: Fixed frequency bands with sliders. Shelving: Simple bass/treble controls. Passive (Pultec style): Unique interaction between boost/cut circuits. Linear Phase: Preserves phase relationship; good for mastering. Dynamic EQ: Frequency‑dependent compression/expansion.

2. The Frequency Spectrum & Subjective Sound | Frequency Range | Subjective Character | Typical Instruments | |----------------|----------------------|----------------------| | Sub‑bass (20–60 Hz) | Feel, rumble, power; can be muddy if too loud | Kick drum sub, 808s, synth bass, pipe organ | | Bass (60–250 Hz) | Thump, warmth, fullness; too much = boomy/muddy | Bass guitar, kick fundamental, low tom, piano left hand | | Low mids (250–500 Hz) | Body, thickness, "boxiness" (around 300–400 Hz) | Guitar body, snare body, lower vocals, horns | | Midrange (500 Hz–2 kHz) | Presence, nasality, aggression; crucial for clarity | Vocals, guitars, synths, snare attack | | Upper mids (2–5 kHz) | Attack, edge, definition; too much = harsh | Vocal consonants, guitar pick attack, snare crack, cymbals | | Presence (5–8 kHz) | Clarity, air, detail | Hi‑hats, cymbals, acoustic guitar sparkle | | Air (8–20 kHz) | Sheen, openness, space; too much = hiss | Overheads, vocal air, reverb tails |
3. Essential EQ Techniques A. Corrective EQ (Fixing Problems) Step 1: Listen for issues
Muddy (250–350 Hz) Boomy (80–120 Hz) Harsh (2–4 kHz) Boxiness (300–500 Hz) Ringing/resonances (notch out with narrow Q) Proper EQ creates clarity, separation, depth, and prevents
Step 2: Use a High‑Pass Filter (HPF)
Cut unnecessary low end on non‑bass instruments. Vocals: HPF around 80–120 Hz. Guitars: HPF around 80–150 Hz. Snare: HPF around 100–150 Hz. Hi‑hats/cymbals: HPF around 300–500 Hz.
