R&B mastering is built around the relationship between sub-bass warmth and vocal intimacy. The 200–400 Hz range. The warmth zone. Is simultaneously where vocal body lives and where excessive low-mid buildup creates mud that obscures the groove. A 1.5–2 dB dynamic cut at 250 Hz, triggered only when low-mids exceed a threshold, keeps warmth without buildup. R&B vocals are the most sensitive element to limiting artifacts. A fast-attack limiter clamps vocal consonants and creates a dulling effect. Set limiter attack above 3 ms to preserve vocal transients. The 808-style bass patterns in contemporary R&B demand sub-bass control below 40 Hz. A high-pass at 30 Hz removes inaudible content that wastes headroom. Stereo imaging in R&B features a wide mid-high stereo field and mono sub-bass. M/S EQ to high-pass the side channel at 80 Hz keeps the bottom end phase-coherent on any playback system. Gentle saturation at 3rd harmonic adds warmth to synthesized basslines that sound artificially clean. Compression ratio for R&B should not exceed 3:1 on the master bus. The genre's gentle dynamics are a core identity feature.
Apple Music context: Apple Music targets -16 LUFS (Sound Check). Mastered for iTunes (now Apple Digital Masters) recommends headroom and 24-bit delivery. Avoid harsh limiting.
How -16 LUFS interacts with R&B / Soul's natural loudness window
R&B / Soul's natural -16 to -13 LUFS loudness sits roughly 1.5 dB hotter than Apple Music's -16 LUFS target, so the platform turns the master down at playback. The competitive instinct to push to -7 or -8 LUFS for "loudness wars" parity is wasted on Apple Music. the platform takes the gain back, and the only result is the dynamic compression you paid for with no perceived loudness benefit. Target -16 LUFS integrated directly and bank the saved dynamic range as wide dynamics for vocal phrasing. The -1 dBTP ceiling specified for Apple Music prevents inter-sample peaks from clipping during the codec's reconstruction filter, which is especially relevant for R&B / Soul's 200-800 Hz vocal body content where high-amplitude transients accumulate against the limiter.
Apple Music delivers AAC at 256 kbps (Apple Digital Masters 24-bit lossless), which preserves the full frequency response of your master without the artifacts (4-6 kHz vocal sibilance) that show up on lower-bitrate platforms. For R&B / Soul, this means the 200-800 Hz vocal body and 80-200 Hz warmth content survives transmission cleanly. The mastering decisions you make in the studio are the decisions the listener hears, with no codec to hide behind. Master conservatively and trust the dynamics. The dynamic-range character of R&B / Soul (wide dynamics for vocal phrasing, 10-14 LU) interacts with this codec tier specifically: preserve the dynamics, the platform will reward them.
Vocal warmth: Gentle boost at 200–300 Hz for chest voice warmth. Avoid cutting this range.
Low-end: Tight high-pass at 35–40 Hz. Keep 80–100 Hz full for bass guitar warmth.
Presence: Gentle 3–5 kHz boost for vocal intelligibility without harshness.
Apple Music: R&B benefits from Apple's high-res formats. Use 24-bit masters for nuanced dynamics.
Gentle glue: Very light master bus compression (ratio 1.5:1 to 2:1). R&B needs natural dynamics.
Smooth limiting: Use lookahead limiting (5–10ms) to avoid transient clipping. Preserve vocal peaks.
Low-mid management: If 250–400 Hz is muddy, apply gentle reduction to clarify the vocal.

Target: -16 LUFS integrated · -1 dBTP true peak · EBU R128 / ITU-R BS.1770-4 compliant
We measure integrated LUFS using K-weighted filtering per ITU-R BS.1770-4: a high-shelf pre-filter at 1681.97 Hz (+3.9998 dB gain) followed by a 75 Hz high-pass (Q=0.5) to remove DC offset and low-frequency rumble. The mean square of the filtered signal gives us integrated loudness in LUFS.
True peak (dBTP) is measured at 4× oversampling to detect inter-sample peaks that occur between digital samples. Sample-peak measurement alone misses these peaks, which cause audible clipping during AAC and MP3 lossy encoding on streaming platforms. We enforce the true peak ceiling at -1 dBTP for all standard platforms.
Genre EQ profiles apply frequency-specific gain based on each genre's sonic characteristics: mud reduction at 250–400 Hz for hip-hop and trap, presence enhancement at 2–4 kHz for vocal clarity on phone speakers, sub-bass high-pass at 30–35 Hz for all genres to remove inaudible subsonic content that wastes headroom.
Master bus compression uses a VCA-style algorithm with genre-tuned attack and release times. Lo-fi and jazz use 50 ms attack to preserve transients; EDM and techno use 5–10 ms for density. Parallel compression blends the compressed signal at 20–40% wet to lift room sound without eliminating the uncompressed transient attack.
The final limiter stage uses lookahead limiting (3–5 ms) to catch transient peaks before they exceed the true peak ceiling. The limiter targets platform-specific LUFS: -14 LUFS for Spotify, -16 LUFS for Apple Music, -11 LUFS for SoundCloud, -9 LUFS for Beatport. Gain reduction is transparent at 1–2 dB of limiting; beyond 3 dB audible artifacts require reducing the input drive.

-16 LUFS integrated. R&B benefits from being slightly less compressed than EDM. A 10-14 LU dynamic range gives the vocals and instruments natural breathing room.
Boost 200–300 Hz gently rather than cutting. Avoid aggressive mid-cut EQ that removes chest voice character. Use gentle multiband compression in the vocal range to control peaks without squashing dynamics.
Yes. Apple Music's 24-bit lossless with Dolby Atmos is increasingly important for R&B. Consider spatial audio mixing.
