How to EQ a Vocal in Your Browser

A 6-band graphic equalizer set up to EQ a vocal, with the 80 Hz band cut and the presence bands lifted

To EQ a vocal, you shape its tone by turning specific frequency bands up or down until the voice sits clearly in the track. In Vocal Cut's free browser equalizer you do this with a 6-band graphic EQ: pull the low band down to remove rumble, dip the low-mids if the voice sounds boxy, and gently lift the upper bands to add presence and air. It runs entirely on your device, takes a few minutes, and needs no account. Here's exactly how to do it.

What you'll need

  • A vocal file — the cleaner and more isolated, the better. EQ can't un-blend a voice that's baked into a full mix. If your vocal is buried in a song, isolate it first (or run the track through the vocal remover) before you EQ.
  • Headphones or decent monitors. Small differences in the top end are hard to judge on laptop speakers.
  • The free equalizer — the graphic EQ tool opens in your browser, no install.

If you're not yet sure what each frequency range does, the primer on what EQ actually does and the guide to audio frequency ranges are worth a quick read first.

The six bands as a map of the voice

The tool is a graphic EQ: the frequencies are fixed, and you control how much gain (from -12 dB to +12 dB) you add or remove at each one. That means classic vocal-EQ advice maps to the nearest available band rather than an exact number — here's how each band translates to a real voice.

Band What it controls on a voice Typical move
80 Hz (low shelf) Rumble, mic handling, plosive thump Cut -3 to -6 dB to clean the bottom
240 Hz (peaking) Warmth, and "boxiness" if there's too much Cut -2 to -4 dB if the vocal sounds muddy
750 Hz (peaking) Body and "honk"/nasal midrange Usually leave flat; small cut if honky
2.2 kHz (peaking) Presence, intelligibility, "forwardness" Lift +1 to +3 dB to bring the voice out
6 kHz (peaking) Clarity, bite — and harsh esses Small lift for clarity, or a small cut to tame sibilance
12 kHz (high shelf) "Air," openness, sheen Lift +1 to +3 dB for a modern, open top

Notice that 6 kHz pulls double duty: it's where a vocal gets its bite and where harsh sibilance lives. You'll usually pick one job for it per vocal.

How to EQ a vocal, step by step

  1. Load your vocal. Drag the file onto the equalizer or click to browse. It decodes on your device — your audio never leaves your device, because there's no server to send it to.
  2. Start previewing. Press Play. Live preview means every slider move changes the sound in real time, so you can hear each decision as you make it rather than exporting to check.
  3. Cut the lows at 80 Hz. Pull the 80 Hz low shelf down 3–6 dB. This is a shelf, not a true high-pass, so it gently rolls off everything below ~80 Hz rather than slicing a hard wall — but it's still very effective for removing rumble and plosive thump, and it clears headroom for everything above.
  4. Dip 240 Hz if it's boxy. If the voice sounds thick, cardboard-y, or "muddy," ease the 240 Hz band down 2–4 dB. Muddiness in a vocal almost always sits in this low-mid region.
  5. Set the presence. To bring the vocal forward and improve intelligibility, lift 2.2 kHz and/or 6 kHz by 1–3 dB. Add a little at a time — this is where a voice goes from "buried" to "in front of the track."
  6. Add air (optional). A small +1 to +3 dB nudge on the 12 kHz high shelf opens up the top end and adds a modern sheen. Skip it if the recording is already bright or hissy.
  7. Tame sibilance if the esses bite. If "s" and "t" sounds are harsh, ease the 6 kHz band down a couple of dB. Be honest with yourself here: this is a static cut, so it reduces those frequencies all the time, not just on the esses. Use a gentle amount and trust your ears — a dedicated de-esser is more surgical, but a small 6 kHz cut solves most cases.
  8. A/B against flat. Hit Flatten to reset every band to 0 dB, then re-apply. Comparing your EQ'd version against the original is the single best way to catch a move that made things worse. If flat sounds better, you overdid it.
  9. Export. When it sounds right, choose your format — WAV (lossless, the default), MP3, or FLAC/M4A — and download.

A few golden rules

These matter more than any specific band:

  • Make small moves. Most of the work happens in the ±1 to ±3 dB range. The sliders go to ±12 dB, but you'll rarely need it — a big boost usually means you're solving the wrong problem in the wrong place.
  • Cut problems before you boost. Removing what's wrong (rumble, boxiness) sounds more natural than piling on what's missing. Reach for a cut first, a boost second.
  • EQ in context, not soloed. A vocal that sounds perfect on its own can vanish or clash once the music is back. If you can, judge it against the backing track. This is also why a muddy overall mix is often several elements fighting in the low-mids, not the vocal alone.

Troubleshooting

It still sounds muddy after cutting 240 Hz. Try a slightly deeper 240 Hz cut, and make sure the 80 Hz shelf is doing its job — leftover low-end energy reads as mud too. If the whole track is muddy, the fix may not be on the vocal at all.

The vocal sounds thin now. You cut too much, or cut too high. Bring the 80 Hz shelf back toward flat, and if you dipped 240 Hz hard, ease it back — that band carries warmth as well as boxiness.

It's harsh or sibilant. Back off any 6 kHz boost first; if it's still spiky, apply a small 6 kHz cut instead. Also check the 12 kHz air — too much shelf can exaggerate esses and breath noise.

The EQ seems to do nothing. Confirm you're previewing (Play is running) and that you actually moved a slider off 0 dB. Very small moves on a quiet vocal can be genuinely subtle — try a more decisive ±3 dB to hear the band clearly, then dial back.

The vocal still sits behind the music. EQ can carve space, but it can't fix a poorly balanced level. Lift 2.2 kHz for presence, but also check the vocal's volume against the track — sometimes it just needs to be louder, not brighter.

Frequently asked questions

Should I high-pass a vocal? Rolling off the extreme low end is standard practice — it removes rumble, plosives, and mic handling noise that a voice doesn't need. This tool doesn't have a true high-pass filter, but its 80 Hz low shelf does the same job gently: pull it down 3–6 dB and you'll clear the bottom without a harsh brick-wall cut, which is enough for most vocals.

What frequencies make a vocal sound muddy? Muddiness in a voice usually lives in the low-mids, roughly 200–400 Hz. On this 6-band EQ the nearest lever is the 240 Hz band — a 2 to 4 dB cut there cleans up boxy, thick, cardboard-sounding vocals. If the whole mix is muddy rather than just the vocal, the culprit is often several instruments crowding that same region at once.

Can I de-ess with an EQ? Partly. Harsh esses sit around 5–8 kHz, and a small cut on the 6 kHz band will reduce them. The catch is that a graphic-EQ cut is always on, so it also dulls the vocal's clarity even when there's no "s" sound. It works for mild sibilance; for heavy, spitty esses a dedicated de-esser that only acts on the loud sibilant moments is more precise.

Do I EQ vocals before or after compression? Both are common, and it depends on the problem. Many engineers make a corrective cut (rumble, boxiness) before compression so the compressor isn't reacting to junk, then make a tonal boost (presence, air) after, so compression doesn't squash the character they just added. If you're only doing one EQ pass, do it and listen — trust the result over the rulebook.
