How to EQ vocals (cut before you boost)

EQ is where you place a vocal in the mix — where you clear the mud, tame the honk, and decide how bright it sits. It's also where a lot of vocals get worse, because the instinct is to boost, and boosting is how you add harshness you then have to fight. Here's how to EQ a vocal so it sits clear and present without turning brittle.

Key Takeaways

• Cut before you boost. Subtractive EQ solves most problems without adding harshness.
• High-pass to clear rumble, dip the mud (200–500 Hz) and any boxy/nasal honk, then gently lift presence or air only if the vocal needs it.
• EQ is static; it's the wrong tool for harsh esses. That's a de-esser's job.
• Small moves. A vocal rarely needs more than a few dB anywhere.

Start by cutting, not boosting

The single most useful habit in vocal EQ: cut what's wrong before you boost what's missing. A subtractive move clears space without adding energy, so it can't introduce harshness. Most "this vocal sounds bad" problems are something in the way — mud, boxiness, a resonant honk — not something absent. Remove the obstacle first, and often you don't need to boost at all.

A practical starting map

Every voice is different, so treat these as places to look, not settings to dial in:

• High-pass (~80–120 Hz): roll off rumble and handling noise the vocal doesn't use. Move it up until the vocal thins, then back off.
• Mud (200–500 Hz): a gentle dip here clears the "blanket over the vocal" feeling. Be conservative; too much and the vocal gets thin.
• Boxy / nasal (500 Hz–1 kHz): if the vocal honks or sounds boxed-in, find the offending frequency by boosting a narrow band, sweeping to the ugliest spot, then cutting there.
• Presence (2–5 kHz): a small lift brings the vocal forward and improves intelligibility. Overdo it and it gets harsh.
• Air (10 kHz+): a gentle high shelf adds openness. Do your de-essing first, or you'll amplify the esses along with the air.

EQ is the wrong tool for esses

Here's a distinction worth being clear about: EQ is static — it's on all the time. A harsh ess is intermittent, there for a few milliseconds per word. If you notch out the sibilant frequency with EQ, you dull the vocal the whole time to fix a problem that's only present some of the time.

That's a de-esser's job, not an EQ's. De-ess the esses dynamically, then EQ the tone statically. We unpack the difference in de-esser vs dynamic EQ, and a phoneme-aware de-esser like Sibilance handles the ess so your air shelf can stay open. It's why de-essing comes before EQ in the vocal chain.

Keep the moves small

Vocals reward restraint. A few decibels of cut and a small presence lift is a complete EQ for most voices. If you're reaching for big boosts, the problem is usually somewhere else — the recording, the mic, or the chain order. Big EQ moves are a sign to look upstream, not a solution.

The short version

Cut before you boost, high-pass the rumble, clear the mud and any honk, then lift presence or air gently. Leave the harsh esses to a de-esser, not a static notch, and keep every move small. That's a vocal EQ that places the voice clearly without making it brittle. Handle the esses first with Sibilance — free tier included — so your EQ only has the good top end to shape.

Sibilance is the single-authority de-esser this comes from — a real free tier, and a 7-day Pro trial with no card.
