Synthwave Mastering for Spotify

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.

What LUFS for synthwave on Spotify?

Target -14 LUFS integrated. Synthwave benefits from a wider 8–12 LU dynamic range that preserves the vintage analog feel. Hard-limiting to -7 or -8 LUFS kills the warm dynamics that define the genre. And gets normalized down anyway.

How do I get authentic analog warmth in a synthwave master?

Apply tape saturation (1–2% harmonics) on the master bus before the limiter. Use an analog-style compressor emulation with slow attack and program-dependent release. Boost 200–400 Hz slightly for synthesizer body. The key is warmth without harshness. Synthwave should sound like a vintage recording, not a polished modern mix.

Does synthwave's analog aesthetic translate on Spotify?

Yes. The warmth frequencies (200–400 Hz) and analog saturation survive streaming compression on Spotify. The gentle high-end rolloff above 12 kHz also ensures the compressed format doesn't add harshness.
