Unveil

R&B mix analysis — scored against real R&B references

Upload a R&B mix and Unveil grades it against a hand-curated reference set of commercially released R&B records — not a generic loudness number. It checks the things that actually matter for R&B: warm low-mids without masking the vocal. Then it hands you the specific fixes for your DAW.

The R&B sound and what listeners expect

R&B is about voice, feel and space. The vocal is intimate, smooth and emotionally upfront, often with layered harmonies and ad-libs; the groove is relaxed but precise; and the low end is warm and round rather than aggressive. Contemporary R&B ranges from sparse, moody, dark productions to bright pop-influenced records, so the details vary, but the common thread is a vocal that feels close and a mix that feels smooth rather than hard.

The challenge is that restraint is a skill. A smooth mix that stays polished and detailed without becoming dull or washed out takes careful control of low-mids, sibilance and reverb.

Tonal balance and typical problems

Expect a healthy bass band (80-250 Hz), which gives the warmth, with a sub band (20-80 Hz) that is present but controlled, often a sine-like 808 or synth bass. The low-mid band (250-800 Hz) is the critical area: it supplies body to the vocal and pads, but too much creates a cloudy, muffled mix, and too little leaves it hollow. The mid band (800-2500 Hz) holds vocal clarity and the body of keys, and the hi-mid band (2500-6000 Hz) provides presence; it is often kept a little softer than in pop. The air band (6000-16000 Hz) gives vocal breathiness and sparkle and is usually smooth rather than bright.

Typical problems: vocal stacks that add up to a thick, boxy 250-500 Hz buildup; sibilance emphasised by heavy compression and a high shelf; too much reverb that blurs the groove; low end that is loose because the bass and kick overlap; and a mix that is so dark that it lacks the definition to compete on playlists. Because the genre prizes warmth, it is easy to overshoot into mud.

Lead vocal, stacks and ad-libs

Treat the lead vocal as the anchor. A typical chain is a high-pass around 80-100 Hz, a cut of 2-3 dB near 250-400 Hz if it sounds boxy, a compressor at 3:1 with a slower attack (15-30 ms) to keep the natural attack of the words and 3-6 dB of reduction, a de-esser around 6-8 kHz, and a gentle lift around 10 kHz for breath. A compressor with some character, such as an opto-style model, is a common choice for its smooth response, but it is a matter of taste.

Harmony stacks need their own treatment. Group them, high-pass them higher (150-250 Hz) than the lead so they do not build up the low-mid, and pan them in pairs, for example 40 and 70 percent either side. Roll off the top above 8-10 kHz and use a slightly darker, wetter reverb than the lead; this makes the stacks sound like a bed around the lead instead of competing. Use ad-libs for movement: pan wide, delay them, and automate their level so they appear in gaps.

Timing matters in stacks. Tighten the starts of words and consonants so that stacked layers sound unified, but keep a little natural looseness in the ends of phrases; perfectly aligned vocals can sound mechanical.

Bass, kick and keeping the groove warm

R&B bass is often a long sub-heavy 808 or synth line, sometimes with a live-style bass guitar. Because the groove is relaxed and the notes are long, bass and kick overlap more than in faster genres. Choose a kick that is short and focused, around 50-70 Hz with a soft click, or choose a longer, rounder kick and duck the bass slightly. A sidechain of 2-4 dB with a release of 80-150 ms is enough; heavy pumping works against the smooth feel.

Add harmonics to the bass by gentle saturation so that the line is audible on small speakers, and keep everything below about 100 Hz in mono. Pad and keyboard layers should be high-passed around 150-250 Hz; a Rhodes or piano with a lot of low-mid content is a main reason R&B mixes become cloudy.

Dynamics and loudness: -10.5 LUFS and DR 9

The reference for R&B is about -10.5 LUFS integrated with a dynamic range around 9, lower in level than trap or EDM. That reflects the genre's priority on vocal nuance and groove over sheer volume. These are references, measured under BS.1770-4 and EBU R128, not rules; a slow jam may be well below that, while an uptempo record may be above.

Streaming normalises playback to around -14 LUFS (Spotify, YouTube) or -16 LUFS (Apple Music), so a -10.5 LUFS master is reduced by roughly 3.5 dB on Spotify. There is no advantage to going louder: pushing the limiter harder flattens the breath and softness in the vocal, raises the noise floor, and makes sibilance more obvious. The expressive quiet-to-loud movement of a vocal performance is a defining feature of the genre, so preserve it.

Keep true peak under about -1 dBTP. Vocals with strong 6-8 kHz energy often create inter-sample overs after limiting, so check with a true-peak meter rather than a sample-peak meter.

Stereo field, reverb and delay

Keep the lead vocal, kick, snare and bass in the centre. Use stereo for keys, pads, guitars, percussion loops and harmony stacks. Reverb is a key part of the R&B palette, but it must be shaped: use a pre-delay of 30-60 ms so the dry vocal remains clear, a decay of 1.5-2.5 seconds, a high-pass at 300-500 Hz and a low-pass around 6-8 kHz. Sidechain or duck the reverb so that tails bloom between phrases.

Delay is often more effective than reverb for creating space without blurring the words. A 1/4 or dotted 1/8 note delay, filtered and mixed 15-20 dB below the vocal, gives depth. Mono-check your reverbs and stereo widening, since big wet signals can narrow or vanish when summed.

Workflow with worked examples

  1. Edit and tune the vocal first; comp the best takes, fix timing on the stacks and check pitch only where it distracts.
  2. Balance drums and bass at a low monitor level until the groove sits without needing the vocal to carry it.
  3. Build the lead vocal chain and automate its level phrase by phrase until it sits consistently.
  4. Group and process the harmony stacks and ad-libs separately from the lead.
  5. Clear the low-mids: look for build-up at 250-500 Hz across keys, pads and vocal stacks, and cut 2-3 dB where it accumulates.
  6. Add reverb and delay returns, filter them, and set their level so they are felt but not heard as a separate layer.
  7. Check balance in mono and at low volume; the vocal should stay intelligible and the groove should hold.
  8. Finish with gentle bus compression, a limiter with a ceiling near -1 dBTP, and a comparison with references at matched loudness.

Common mistakes and a final checklist

Frequent mistakes include stacking harmonies without high-passing them, using so much reverb that the groove loses definition, boosting air to compensate for a dull vocal while ignoring sibilance, over-widening the stereo image, allowing the bass to run loose, and over-compressing a vocal so the dynamic expression disappears.

What you get

Questions

What loudness should a R&B mix hit?

Unveil targets roughly -10.5 LUFS integrated for R&B, but loudness alone doesn't make a mix — it's weighed alongside dynamics (DR ~9), tonal balance, phase, and frequency conflicts.

Is the R&B scoring just a generic algorithm?

No. R&B is scored against measured statistics from a curated set of released R&B tracks, so the targets reflect how the genre is actually mixed and mastered.

Is it free?

Yes — analysis is free with a quick sign-up. The optional Fix My Mix mastering pass is paid.
