How to EQ Vocals — Exact Frequencies That Work

The Complete Vocal EQ Map

Here are the critical frequency zones for vocal EQ, from bottom to top:

Below 80Hz — High-Pass Everything

There is nothing useful in a vocal track below 80Hz. What's down there is mic rumble, HVAC noise, handling noise, and the low-frequency component of plosive sounds ("p" and "b" consonants). Apply a high-pass filter with a 12dB/octave slope at 80-100Hz on every vocal, every time. This cut alone makes a noticeable improvement on most home recordings.

200–400Hz — The Mud Zone

This range is where "boxy," "muffled," or "phone-sounding" tones live. When a vocal sounds like it was recorded in a cardboard box, this is usually why. Use a narrow bell cut (Q of 2-4) and sweep slowly to find the worst buildup — it'll jump out at you. Cut 3-6dB. Be careful not to over-cut or the vocal will lose body and warmth.

800Hz–2kHz — The Nasal Range

This is where nasal, honky, or "thin" vocals get their character. Some singers have natural resonance here that can get fatiguing in a mix. A moderate cut (2-4dB, Q of 1.5-2) can open the mix and reduce listener fatigue without making the vocal sound hollow. This is a "cut if needed" zone — not every vocal has a problem here.

3–5kHz — The Presence Zone

This is the most important EQ zone for vocal intelligibility. Boosting here (1-3dB, bell shape, Q of 1-1.5) makes vocals "cut through" a dense mix — you can hear every word clearly even when the instrumentation is full. This is an additive boost, applied after corrective cuts. The exact frequency depends on the vocalist: male voices tend to benefit from boosts lower in this range (3-3.5kHz), female voices higher (4-5kHz).

5–8kHz — Sibilance (Handle With De-Esser)

This zone is where "s," "t," and "sh" sounds become harsh and distracting — especially after compression has already made them louder. Don't try to fix sibilance with static EQ cuts. A static cut takes the life out of the vocal and still sounds wrong when the sibilant sounds arrive. Use a de-esser (dynamic EQ or dedicated plugin) that only engages when the harshness actually occurs.

10kHz and Above — Air and Shimmer

A gentle high-shelf boost above 10kHz (1-3dB) adds "air" — that open, breathy, spacious quality that makes a vocal sound expensive. Use a shelf rather than a bell for this boost. Too much and you'll emphasize breath noise and make the vocal harsh. Too little and it makes no difference. Experiment in 0.5dB increments.

The Order Matters

Always do corrective EQ cuts before additive boosts. Cut the 200-400Hz mud, pull back any nasal buildup, then boost presence and air. If you boost presence first and then cut mud, the cut affects the presence you just added. Correct → then enhance, in that order.
