Mix character
Boom bap is the New York hip hop of the 1990s and its heirs: sampled drums up front (short, round kick; dry, "cracking" snare), a soul, jazz or funk sample as the harmonic bed, short bass (often in the sample or played), and a dry, forward rap vocal. Tempo 85–95 BPM with swing. The classic sound comes from 12-bit samplers (SP-1200, MPC60) and vinyl records: grain, filters and heavy compression are part of the aesthetic.
Typical balance
| Element | Level relative to the mix |
|---|---|
| Rap vocal | −4/−6 LU |
| Snare | −7/−9 LU |
| Kick | −8/−10 LU |
| Bass (or sample low end) | −8/−10 LU |
| Melodic sample | −8/−11 LU |
| Hi-hat | −12/−15 LU |
The drums hit harder than in trap relative to the low end: the groove comes from kick and snare, not from the 808.
EQ
- Kick: body 60–90 Hz, punch 100–150 Hz, light click 2–4 kHz; keep it short.
- Snare: body 180–250 Hz, crack 2–5 kHz; vinyl noise and natural tail.
- Sample: HP 100–200 Hz (kick and bass carry the low end), LP 8–12 kHz for vintage color, cut 2–4 kHz if it masks the vocal.
- Bass: 60–120 Hz, mids 500 Hz–1 kHz; no long sub.
- Vocal: HP 80–100 Hz, presence 3–5 kHz, moderate air.
Dynamics
- Drum bus: 3–6 dB of compression (FET or VCA) + tape saturation or a light bitcrusher (12-bit) for grain.
- Parallel drum compression for punch.
- Vocal: serial compression 6–10 dB, de-esser, consistent level.
- Mix bus: glue 1–2 dB.
Space
- Nearly mono drums, sample with moderate width, vocal in the center.
- Short reverbs (room 0.3–0.8 s) or none on the vocal; doubles only on the final words.
- The character is forward and compact, not airy.
Layering
- Kick and snare are often reinforced with another sample (attack or body), aligned.
- Filtered sample in two copies: one with an HP for the mids, one with an LP for warmth, if you need more control.
Reference loudness
Modern masters −10/−8 LUFS, true peak −1 dBTP, crest factor 8–11 dB. Classic records were less loud (−12/−10 in remasters).
Reference tracks
Nas "N.Y. State of Mind", Gang Starr "Mass Appeal", Pete Rock & CL Smooth "They Reminisce Over You (T.R.O.Y.)", A Tribe Called Quest "Electric Relaxation", Mobb Deep "Shook Ones, Pt. II", Joey Bada$$ "Christ Conscious".
Common mistakes
- Long 808s instead of a short bass: the genre changes character.
- A sample full of low end that clashes with the kick.
- Vocal with long reverbs: it loses its immediacy.
- Clean, modern drums without grain: anonymous sound.
Starting settings
| Parameter | Value | Why |
|---|---|---|
| Vocal | −4/−6 LU, 6–10 dB | Forward rap. |
| Drum bus | 3–6 dB + saturation or 12-bit | Drums with grain and punch. |
| Sample | HP 100–200 Hz, LP 8–12 kHz | Warm bed that doesn't mask. |
| Stereo | Nearly mono drums, moderate sample | Compact sound. |
| Swing | 55–62% on sixteenth notes | The genre's groove. |
| Master loudness | −10/−8 LUFS | Modern level. |
Frequencies to watch
| Range | What to do |
|---|---|
| 60–90 Hz | Body of the short kick; the bass sits above it or alternates with it. |
| 100–200 Hz | Sample HP: low end left to kick and bass. |
| 180–250 Hz | Snare body. |
| 2–5 kHz | Snare crack and vocal presence: make room over the sample. |
| 8–12 kHz | Sample LP for vintage color. |
Example chain
| Step | Tool | Settings | Why |
|---|---|---|---|
| Drums | Samples → EQ → bus → compression + light bitcrusher | 3–6 dB | Punch and grain. |
| Sample | EQ (HP/LP) → tape saturation | Filters 100 Hz–12 kHz | Vintage color. |
| Bass | EQ → compression | 3–5 dB | Short, consistent notes. |
| Vocal | EQ → FET → de-esser → opto | 6–10 dB | Dry, forward vocal. |
| Master | Glue → limiter | −10/−8 LUFS | Level. |
How to check the result
- Master crest factor 8–11 dB: below 7 dB the drums lose their punch.
- Correlation +0.5/+0.9 (compact mix); Sub and Bass Side/Mid at −20 dB or lower.
- Sub band (20–60 Hz) at least 3–4 dB lower than the Bass band (60–120 Hz): no long subs.
- High-mid band: the vocal stands out over the sample.
- Air band 2–4 dB lower than pop references (vintage color) but not absent.
