the ear

bright sounds have lots of energy above ~3-4kHz. cymbals + hi-hats + air + breath all live in this range. a bright mix feels open, alive, modern. too bright = harsh + ear-fatiguing.

dark sounds have less energy above ~3kHz. cymbals sit back, vocals feel inside the speaker not outside. classic on dub, sade, mid-90s downtempo. too dark = muffled + boring.

a round sound has even energy across 200Hz-3kHz — no resonant peaks, no scoops, just a smooth hill. vocals sound full + relaxed. mixes feel pro. it's the goal state for most acoustic-feeling productions.

a nasaly sound has too much energy in the 1-2kHz band (the 'nose' frequency in human voice) + scooped lows + scooped highs. it sounds like you're singing through your nose. on vocals it kills warmth; on synths it can be a feature (acid bass, 303).

a punchy sound has fast attack + fast decay. you feel the strike physically. kicks + snares + slap-bass + claps are usually punchy by design.

smooth sounds have slow attack + long sustain + gentle release. pads, strings, ambient washes, R&B vocals on a ballad. no scary transients, no surprises.

crisp sounds have clear top-end + sharp transients + no muddiness. hats sound clear, vocals sound articulate, every detail is audible. modern productions lean crisp.

dusty sounds carry the wear of analog playback — vinyl crackle, tape hiss, slight high-end roll-off, slight wow + flutter. lofi hip-hop, J Dilla beats, Madlib productions all aim dusty.

woody sounds have body resonance — bass guitars, double basses, marimbas, log drums all woody. specific 100-250Hz peaks that the ear reads as 'a wooden box vibrating.'

plastic sounds are synthetic in the WORST way — every preset that comes with a budget DAW. no body, no character, no analog warmth, no human imperfection. usually a problem.

boomy is too much energy in a narrow low band, usually 100-200Hz, that rings longer than it should. it's almost always a ROOM problem masquerading as a mix problem — your monitors are exciting a mode in an untreated room, so you hear bass that isn't really on the record. it makes kicks and basslines feel loose and one-note instead of tight.

boxy lives at 300-500Hz — the frequency of a cardboard box, a small wooden room, a cheap acoustic guitar body. when a sound is boxy it feels closed-in and cheap, like it was recorded in a closet. super common on drum overheads, room mics, and any sound that was recorded in an untreated small space.

harsh is the 2-5kHz range pushed too hard — the band your ear is MOST sensitive to (evolution: it's where a baby's cry lives). a little gives presence and bite; too much and the sound stabs, fatigues you in minutes, and gets worse the louder it goes. digital distortion, cheap cymbals, and over-EQ'd vocals all go harsh.

muddy is the most common mix complaint there is. too much energy stacked in 200-400Hz across multiple sounds — kick, bass, vocal low end, guitar body, pad — all piling into the same band until nothing has its own space. the mix sounds thick but undefined, like everything's behind a curtain.

airy is the very top — above 10kHz, the 'air band.' it's not brightness (that's 3-6kHz); it's the sheen and openness above that, the sense that a sound is breathing in a real space. vocals, cymbals, and acoustic guitars come alive with air. it reads as expensive, modern, hi-fi.

present means a sound feels close and forward, right in your face — driven by the 3-5kHz 'presence' band. it's how you make a vocal cut through without turning it up. the opposite is a sound that feels distant or buried. presence is about FORWARDNESS, not volume.

woolly (or 'woolen') is muddy's softer cousin — a lack of definition in the low-mids combined with rolled-off highs, so the sound feels like it has a blanket over it. warm but vague. no transient snap, no top-end clarity. often from too much low-mid + a slow attack + dark source.

brittle is high-end with nothing underneath it. the treble is there — even excessive — but there's no low or low-mid body to support it, so the sound feels fragile, glassy, like it could shatter. common on cheap digital sources, over-compressed samples, and anything bit-crushed wrong. brittle = thin + harsh together.

honky is a concentrated bump around 500-800Hz — the 'cupped hands' or 'megaphone' frequency. it's nasaly's lower neighbor. a honky sound feels pinched and forward in an unpleasant, telephone-y way. common on cheap speakers, horn-loaded cabinets, and DI'd guitars/synths with a midrange resonance.

scooped is the opposite of honky/present — the mids (especially 400Hz-2kHz) are pulled DOWN while the lows and highs are boosted, making a 'smiley face' on the EQ. it sounds huge and hi-fi on its own, but scooped sounds DISAPPEAR in a mix because the midrange is where a mix's intelligibility lives. classic beginner mistake + classic metal guitar tone.
