EQ is the tool that turns a thin or muddy mic into a voice that cuts cleanly through your game and music. It sounds intimidating, but a stream vocal only needs a few well-placed moves. Here is a starting-point EQ you can adjust by ear, plus what each band actually controls.
What EQ does
Equalization boosts or cuts specific frequency ranges. Your voice spans lows that add warmth, mids that carry intelligibility, and highs that give it air and clarity. Good EQ removes what muddies the sound and gently lifts what helps you be understood, without making you sound unnatural.
A safe starting curve
| Band | Move | Why |
|---|---|---|
| Below 80 Hz | High-pass (cut) | Removes rumble, fan, desk thumps |
| 200–400 Hz | Cut 2–4 dB if muddy | Reduces boxiness |
| 3–5 kHz | Boost 2–3 dB | Adds presence and clarity |
| 10 kHz+ | Gentle shelf boost | Adds air (careful of sibilance) |
Work in cuts before boosts
The most useful EQ move is the high-pass filter: roll off everything below about 80 Hz to kill low rumble, keyboard thumps, and desk vibration your ears do not miss. Next, if your voice sounds boxy or muddy, a small cut around 250–350 Hz cleans it up more than any boost. Only after cutting should you add a modest presence lift around 3–5 kHz so your words sit clearly on top of game audio.
Handle the highs carefully
A gentle shelf above 10 kHz adds “air” and a polished feel, but push it too far and you exaggerate sibilance and breath noise. Boost in small steps and listen on cheap earbuds, since that is what many viewers use. If the highs start to sting, you have gone too far; pull it back and, if needed, add a light de-esser after the EQ.
Match the EQ to your mic
A warm, dark dynamic mic may want a touch more presence in the 3–5 kHz range, while a bright condenser often needs the opposite: less high-shelf and maybe a small cut around 6–8 kHz to control harshness. There is no universal curve; the table is a starting point. Record a test clip, tweak one band at a time, and stop as soon as your voice sounds clear and natural rather than processed.
Tuning EQ to your voice, not a preset
Downloaded EQ presets are a trap because they were built for someone else’s voice, mic, and room. A curve that adds warmth to a thin voice will turn a naturally deep voice into mud, and a presence boost that helps a dull dynamic mic will make a bright condenser harsh. Use the starting table as a direction, then adjust one band at a time while listening to your own recorded speech, and stop the moment it sounds clear and natural rather than pushing for a dramatic change.
A useful trick for finding problem frequencies is the “boost and sweep”: temporarily add a narrow, strong boost, sweep it slowly across the low-mids, and the spot that sounds boxiest or most honky is the one to cut, gently, once you remove the boost. This finds the exact mud frequency for your voice far faster than guessing. Keep every final move under a few decibels, favor cuts over boosts, and check the result on cheap earbuds, because subtle, personal EQ is what reads as professional while heavy presets read as processed.
FAQ
Should EQ come before or after compression?
Usually EQ first to shape the tone, then compression to even the level. Some prefer a subtractive EQ before and a small tone EQ after; either works if you use gentle moves.
How much boost is too much?
If any single band is boosted more than about 4–5 dB, you are probably fixing the wrong thing. Try a cut elsewhere or better mic placement before big boosts.
Bottom line
Start with a high-pass below 80 Hz, a small cut around 250–350 Hz if muddy, and a gentle presence lift at 3–5 kHz, adjusting for whether your mic is warm or bright. Favor cuts over boosts, keep every move under a few dB, and check on cheap earbuds. Subtle EQ makes your voice clear and effortless; heavy EQ makes it sound processed.
