R&B Mix Check — Does Your Vocal Sound Like a Whisper or a Confession?
R&B is the genre where the vocal is the song. A whisper, a falsetto run, a harmony stack that curls around the lead — every syllable has to feel close, intimate, and intentional. But underneath sits a sub bass, a soft kick, and a bed of pads that can swallow all of that nuance if the low end isn't managed. MixDiagnose tells you where your vocal is being masked and where your low end is fighting for room.
The Frequencies R&B Mixes Live In
Modern R&B is built on two things: a sub-driven low end and a vocal that feels like it's right next to your ear. Five zones where the genre consistently breaks:
- 30–80 Hz — The sub bass and 808 fundamental. R&B subs are deep and sustained, not punchy. Too much and it overwhelms earbuds; too little and the track feels thin on a system.
- 100–250 Hz — The warmth zone. Bass guitar body, low piano, and the chest of the vocal live here. This is what makes the mix feel "expensive" — or muddy when it piles up.
- 300–800 Hz — Pad and key buildup. Lush Rhodes and synth pads fill this range and create a blanket that dulls the vocal's lower harmonics.
- 2–5 kHz — Vocal presence and intimacy. R&B vocals need to sit forward without becoming harsh. Too little and the emotion reads as distant; too much and every breath becomes aggressive.
- 6–10 kHz — Sibilance territory. Close, breathy vocals pile up sibilants here. One bright "S" on every line fatigues the listener fast.
Common R&B Mixing Mistakes
The sub eats the vocal. A sustained 808 or sub bass at -10 dB pulls the mix's energy down where earbuds can't reproduce it, leaving the vocal sounding thin and disconnected. We flag when sub energy below 80 Hz is pulling loudness away from the midrange where the vocal lives.
Harmonies drowning the lead. Stacked vocal doubles and harmonies are an R&B signature — but if they're at the same level and width as the lead, the lyric loses its front-and-center position. We detect when side energy from harmonies exceeds the mono center where the lead should sit.
Over-compressing the emotion. R&B vocals move from a whisper to a belt. A single compressor chained hard kills that dynamic storytelling and makes everything feel flat. We report crest factor and dynamic range so you know if you've squeezed the life out of the performance.
Pads masking the lower vocal harmonics. Those warm Rhodes and pads sit right where the vocal's chest resonance lives (300–800 Hz). When they're too loud, the vocal loses body and reads as thin. We identify spectral masking in that band with severity in dB.
Sibilance from close mixing. R&B vocals are often recorded close for intimacy — which means sibilants are hot. We flag sibilance buildup at 6–10 kHz so you know where to de-ess before it fatigues the listener.
What MixDiagnose Checks for R&B
- Vocal masking — Spectral overlap between the lead vocal and pads/keys at 300–800 Hz, and between vocal and harmonies at 2–5 kHz.
- Sub-bass balance — Energy distribution below 80 Hz vs. the midrange, so your sub isn't stealing headroom from the vocal.
- Harmony vs. lead width — Mid-side analysis to confirm the lead sits in the center and harmonies stay wide.
- Dynamic integrity — Crest factor and dynamic range to preserve the whisper-to-belt movement R&B demands.
- Sibilance detection — Buildup at 6–10 kHz flagged before it fatigues the ear.
- Loudness and streaming fit — LUFS and true peak vs. Spotify (-14), Apple (-16), and YouTube (-14) so your intimate vocal still clears normalization.
Every finding comes with a fix. "Your pads are 2.4 dB louder than your vocal at 480 Hz — cut the pads 2 dB at 500 Hz or sidechain them to the vocal."
