The Mastering Chain: Why Order Matters

EQ before compression, compression before limiting. The order of processing changes the result dramatically.

Professional mastering follows a specific signal flow. Each stage builds on the previous one, so changing the order changes the sound. Here is LoudCraft's chain and why each step is where it is.

LoudCraft's mastering chain 1. Corrective EQ - Fixes problems: rumble removal, tilt correction, harshness and mud reduction 2. Multiband compression - Controls each frequency range on its own 3. Mastering EQ - Tonal polish: warmth, presence, air, genre-specific shaping 4. Dynamic EQ - Tames resonances only when they flare up 5. De-esser - Softens harsh sibilance 6. M/S EQ - Shapes the center and the sides separately 7. Spatial processing - Stereo width enhancement with mono-safe controls 8. Harmonic enhancer - Adds subtle harmonic richness 9. Section dynamics - Lets choruses and drops open up while quieter parts breathe 10. Transient shaper - Restores punch and definition 11. Bus compressor - Glue for cohesion 12. Loudness normalization - Brings the master to your LUFS target 13. True Peak Limiter - Final ceiling at -1 dBTP (-2 dBTP for masters louder than -14 LUFS and for cinema and ATSC targets); for loud targets (-10 LUFS and above) a transient soft clipper helps it

The Construction Analogy You would not paint the walls before fixing the cracks (corrective EQ first). You would not install the roof before building the walls (limiter last). Each stage assumes the previous one is done correctly.

Warning: The Tonal Adjustment panel and Parametric EQ in Compare work AFTER the limiter. They are post-mastering tools. This means any boost you apply does not go through the limiter - it goes directly to the output. Keep adjustments subtle (1-2 dB) to avoid introducing peaks above the safe ceiling.

Key takeaway: LoudCraft handles the chain order automatically. Understanding it helps you make better decisions about when to use engine-level processing vs post-master tools.
