Multiband Compression in Mastering: Taming Bands Without Squashing Punch

Multiband compression in mastering controls frequency regions independently. Learn band splits, subtle gain reduction, and when multiband beats full-band limiting.

Multiband compression in mastering divides the signal into frequency bands (low, low-mid, high-mid, air) and applies independent dynamics control per band. Used sparingly, it can tame a boomy low-mid without touching vocal presence — overused, it creates phasey, lifeless masters.

Key takeaways
  • Mastering multiband moves are subtle — often 0.5–2 dB gain reduction per band
  • Crossover points matter: typical splits around 120 Hz, 800 Hz, 3 kHz, 8 kHz
  • Fix heavy problems in mixing; multiband mastering is polish, not rescue
  • Compare against Multiband Compression in Mixing

When to use multiband on the master

Good candidates: low-mid buildup that a wide-band compressor would over-duck; inconsistent sub level; occasional harsh sibilance band. Poor candidates: fixing a muddy mix, adding loudness via multiband limiting alone, or replacing proper mix balance.

Settings starting points

Low band: slow attack, medium release, 1–2 dB GR on sustained bass notes. High band: fast attack for de-essing effect on sibilance, 1–3 dB GR max. Use linear-phase crossovers when available to reduce phase smear. Always bypass and A/B — if you cannot hear a clear improvement, remove it.
