Why Metal on Bandcamp Needs Specialized Mastering
Metal mastering is unique: the loudest sustained signals are guitars — not kick, snare, or bass — and the distortion character is the genre's sonic identity. Heavy saturation from high-gain amplifier simulation creates harmonic content extending up to 18–20 kHz, meaning the true peak almost always sits in harmonic overtones rather than at the fundamental frequency. A true peak limiter at -1 dBTP is non-negotiable — sample peak measurement at -0.3 dBFS will still produce inter-sample peaks above 0 dBFS from harmonic guitar stacks. The kick drum in metal occupies a narrow window: the transient click at 2–4 kHz must punch through the guitar wall, while the sub-bass body at 60–80 Hz anchors the bottom. Sidechain compression between kick and distorted bass is typically handled at the stem level before mastering, but M/S processing on the master bus can enhance kick clarity by boosting 2–3 kHz in the mid channel while keeping guitar density in the sides. Dynamic range targets of 4–7 LU are typical — listeners expect density. High-pass at 30 Hz removes subsonic content; keep the 60–80 Hz kick fundamental fully intact for maximum perceived punch on any system.
Bandcamp context: Bandcamp serves independent artists and quality-focused listeners with lossless FLAC downloads at full quality. Bandcamp applies no loudness normalization — preserve your dynamic range. Audiophile listeners value wide dynamics over loudness. A -14 to -18 LUFS master with 12+ LU dynamic range impresses discerning ears.
Metal EQ Profile for Bandcamp
Guitar density: Scoop 200–400 Hz slightly to reduce muddiness from heavy downtuned guitars.
Presence: Boost 2–5 kHz for guitar presence and vocal intelligibility through the density.
Kick clarity: High-pass kick at 50 Hz. Boost 60–80 Hz body and 2–4 kHz click for punch.
Bass clarity: Cut 200–300 Hz from bass guitar to separate it from the guitar low-mid density.
Compression & Limiting for Bandcamp
Aggressive limiting: Metal tolerates hard limiting for maximum impact. 4-7 LU dynamic range.
Multiband: Control guitar low-mids (200–500 Hz) independently — this is where metal masters get muddy.
Sub control: High-pass at 30–40 Hz. Metal doesn't need sub-bass — it needs aggressive mid-range presence.

Master Free NowTechnical Methodology — Metal Mastering for Bandcamp
Target: -14 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.

Metal Mastering FAQ — Bandcamp
What LUFS for metal on Bandcamp?
-14 LUFS integrated. Metal can push hard — a 4–7 LU dynamic range at -14 LUFS is competitive and powerful. Over-limiting at -8 LUFS will be normalized down anyway.
How do I prevent the mix from sounding muddy in the master?
Cut 200–400 Hz with a multiband compressor or EQ to clear guitar mud. This is the most common metal mastering problem. Also ensure bass guitar has its own frequency space by cutting its 200–300 Hz slightly.
How does heavily compressed metal sound on Bandcamp?
Bandcamp normalizes to -14 LUFS, so an over-limited -8 LUFS metal master gets turned down to the same volume as a well-mastered -14 LUFS version, while sounding squashed and fatiguing. Master at the target LUFS with maximum 7 LU dynamic range.
