Problem
Broadcast-style loudness processing reduces music impact because the limiter is driven mainly by narration peaks.
Solution
Root Cause / Diagnostic:
Passing a full master mix (dialogue, sound effects, and music) through an aggressive broadcast limiter causes dialogue peaks to trigger master gain reduction. When the host speaks loudly, the limiter clamps down the master bus, pulling down concurrent musical instruments and bass frequencies alongside the voice. This side-effect suppresses musical energy and dynamic punch during intense narrative moments.
Actionable Fix:
1. Decouple loudness processing: apply independent leveling and limiting to the dialogue submix bus before it reaches the master summing stage.
2. Insert a sidechain high-pass filter (set to 100 Hz) on the master bus limiter to prevent low-end bass transients from unnecessarily driving global gain reduction.
3. Adjust the final limiter threshold to achieve no more than 1 to 2 dB of transparent peak limiting on composite programmatic peaks.
Pro Tip:
Mix your music bed to sit 12 to 15 dB below dialogue integrated loudness, using subtle automated volume automation rather than master bus limiting to maintain musical dynamic punch.
