Frequency Chart
A quick reference for where instruments live in the spectrum, where problems usually hide, and what the words engineers use actually mean in Hz. Keep this page open while you mix.
Every recording is different. A "mud" area of 250 Hz on one vocal might be 400 Hz on another. Use these ranges to know where to start sweeping, then trust your ears. The EQ lesson explains how to sweep and cut.
The Spectrum at a Glance
| Region | Range | Feel | Too much | Too little |
|---|---|---|---|---|
| Sub-bass | 20–60 Hz | Weight, rumble | Boomy, eats headroom | Thin on big systems |
| Bass | 60–250 Hz | Warmth, punch | Boomy, heavy | Thin, weak |
| Low mids | 250–500 Hz | Body | Muddy, boxy | Hollow, cold |
| Mids | 500 Hz–2 kHz | Presence of most instruments | Honky, nasal | Scooped, distant |
| Upper mids | 2–6 kHz | Clarity, attack | Harsh, fatiguing | Dull, lifeless |
| Highs | 6–12 kHz | Brilliance, sibilance | Sibilant, brittle | Muffled |
| Air | 12–20 kHz | Openness, sparkle | Hissy | Closed-in |
Instrument Frequency Ranges
The fundamental range is where the notes themselves sit (the lowest to highest pitches the instrument normally plays). Harmonics extend much higher, which is where most of the character lives.

Problem Frequency Words
Engineers use descriptive words to talk about tone. Learn what each word means, and which way to move the EQ.
| Word | Typical range | Sounds like | Usual fix |
|---|---|---|---|
| Rumble | 20–40 Hz | Low noise from traffic, handling, air conditioning | High-pass filter |
| Boomy | 60–150 Hz | Too much bass, a ringing low end | Cut or high-pass; check the room |
| Muddy | 200–400 Hz | Thick, cloudy, unclear | Wide cut of 2–4 dB, often on several tracks |
| Boxy | 300–600 Hz | Recorded inside a cardboard box | Narrow-to-medium cut |
| Honky | 600 Hz–1.2 kHz | Like a horn or a megaphone | Cut a few dB |
| Nasal | 800 Hz–1.5 kHz | Talking with a pinched nose | Narrow cut |
| Harsh | 2–5 kHz | Hard, piercing, tiring after a few minutes | Narrow cut or dynamic EQ |
| Sibilant | 5–10 kHz | Hissing "s" and "sh" sounds | De-esser |
| Brittle / tinny | Too little below 500 Hz, too much 3–8 kHz | Thin and sharp | Cut highs, add some low mids |
| Airy | 10–20 kHz | Open, breathy, expensive (a good thing) | Gentle high shelf boost of 1–3 dB |
| Warm | 100–300 Hz | Full and pleasant (a good thing) | Gentle boost, or saturation |
| Presence | 3–6 kHz | Up front, close, intelligible | Small boost on the lead |
Hear It: EQ Moves
- Put an EQ on a vocal or full loop (Ableton: EQ Eight; FL Studio: Fruity Parametric EQ 2; Logic: Channel EQ).
- Make a narrow boost of about
+10 dBand sweep it slowly from 100 Hz to 10 kHz. - Stop when you hear one of the words in the table above (muddy, boxy, nasal, harsh, sibilant). Note the frequency.
- Turn the boost into a cut of 2–4 dB at that frequency and widen it slightly. Compare with the EQ bypassed at matched level.
Note-to-Frequency Table
These are the standard frequencies for equal temperament tuning with A4 = 440 Hz. Each octave doubles the frequency. Middle C is C4.
A notes
| Note | Frequency | Where you hear it |
|---|---|---|
| A0 | 27.5 Hz | Lowest key on a piano |
| A1 | 55 Hz | Low 808 and sub notes |
| A2 | 110 Hz | Open A string on a guitar |
| A3 | 220 Hz | Low male vocal range |
| A4 | 440 Hz | Tuning reference (concert A) |
| A5 | 880 Hz | High female vocal range |
| A6 | 1,760 Hz | High whistles, piccolo, synth leads |
| A7 | 3,520 Hz | Near the top of the piano |
C notes
| Note | Frequency | Note | Frequency |
|---|---|---|---|
| C1 | 32.70 Hz | C5 | 523.25 Hz |
| C2 | 65.41 Hz | C6 | 1,046.50 Hz |
| C3 | 130.81 Hz | C7 | 2,093.00 Hz |
| C4 (middle C) | 261.63 Hz | C8 | 4,186.01 Hz |
Useful low notes for bass and 808s
| Note | Frequency | Note | Frequency |
|---|---|---|---|
| E1 | 41.20 Hz | A1 | 55.00 Hz |
| F1 | 43.65 Hz | B1 | 61.74 Hz |
| G1 | 49.00 Hz | C2 | 65.41 Hz |
The formula
Use this to tune a kick or 808 to the key of your song: find the root note's frequency, then tune the drum's fundamental to match.
DAWs don't agree on octave numbers. Ableton and Logic (by default) label middle C as C3, and FL Studio labels it C5. The frequency is the same, 261.63 Hz; only the name changes. See MIDI.
A4 is Hz, so A5 is Hz.
A thick, cloudy sound around 200–400 Hz is usually called .
1. A vocal sounds harsh and tiring. Where should you start looking?
- 40–80 Hz
- 200–400 Hz
- 2–5 kHz
- 15–20 kHz
Harshness usually lives in the upper mids, where the ear is most sensitive.
2. What tool usually fixes sibilance best?
- A de-esser
- A high-pass filter at 100 Hz
- A low shelf boost
- A longer reverb
A de-esser reduces only the "s" sounds when they happen, instead of dulling the whole vocal.
3. What frequency is A2?
- 55 Hz
- 110 Hz
- 220 Hz
- 440 Hz
A4 is 440 Hz. Halve it twice: A3 is 220 Hz and A2 is 110 Hz.
4. A kick sounds like someone hitting a cardboard box. Which range should you cut?
- 30–50 Hz
- 3–5 kHz
- 10–15 kHz
- 250–500 Hz
The boxy, cardboard tone of a kick sits in the low mids. A modest cut there cleans it up.
