Why Metal on SoundCloud 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.
SoundCloud context: SoundCloud uses aggressive loudness normalization and transcodes to 128kbps MP3. Master slightly louder (-11 to -13 LUFS) and ensure clarity survives MP3 compression.
Metal × SoundCloud. The Normalization Math
How -11 LUFS interacts with Metal's natural loudness window
Metal's natural -10 to -7 LUFS loudness sits roughly 2.5 dB hotter than SoundCloud's -11 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 SoundCloud. the platform takes the gain back, and the only result is the dynamic compression you paid for with no perceived loudness benefit. Target -11 LUFS integrated directly and bank the saved dynamic range as dense and aggressive. The -0.5 dBTP ceiling specified for SoundCloud prevents inter-sample peaks from clipping during the codec's reconstruction filter, which is especially relevant for Metal's 80-200 Hz guitar body content where high-amplitude transients accumulate against the limiter.
Codec Reality for Metal on SoundCloud
SoundCloud encodes at 128 kbps free / 256 kbps Go+ and plays primarily through compressed-tier streams. the listener's playback chain destroys content below 60 Hz and rolls off above 12 kHz before your master ever reaches their ear. Metal's 80-200 Hz guitar body and 2-5 kHz attack content needs to translate at 100-200 Hz low-mid smear and 10 kHz+ rolloff or it disappears from the playback. Harmonic-exciter saturation that re-creates fundamentals as upper harmonics is more useful than EQ boosts on this platform: phone speakers can reproduce harmonics that they cannot reproduce as fundamentals. The dynamic-range character of Metal (dense and aggressive, 5-7 LU) interacts with this codec tier specifically: compress conservatively, then let the codec do the rest. Over-compression at the mastering stage stacks with the codec's loudness handling and produces a flat, fatigued listening result.
Metal EQ Profile for SoundCloud
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 SoundCloud
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.

Technical Methodology. Metal Mastering for SoundCloud
Target: -11 LUFS integrated · -0.5 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. SoundCloud
What LUFS for metal on SoundCloud?
-11 LUFS integrated. Metal can push hard. A 4–7 LU dynamic range at -11 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 SoundCloud?
SoundCloud normalizes to -11 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.
