The Loudness War

Pushing the master to the ceiling buys loudness at the cost of dynamics and impact.

The problem

On the same pair of headphones the louder version always seems better, so records grew louder for decades. Limiters pinned peaks to the ceiling, quiet passages were pushed up, and dynamic range quietly disappeared. Streaming loudness normalisation has shrunk the payoff, but the habit remains.

How it works

Dynamic range is the distance between the loudest and quietest moments. A compressor narrows that distance and a limiter shaves peaks at the ceiling. Raising average level continuously robs transients of their point, turns drum impact into a wall and takes the breath out of quiet passages. Long exposure to high level also tires the ear, so the music stops feeling exciting. Platforms normalise playback loudness, turning down over-hot tracks, but the dynamics that were crushed do not come back.

Settings and practice

Treat dynamics as content at the mixing stage and leave real contrast between sections. At mastering, let the limiter catch occasional overshoots rather than flattening everything. Set integrated loudness to the delivery target, often a few LU below the loudness of past pop records in exchange for better transients. When something needs to feel louder, look at arrangement and orchestration before reaching for the limiter. Compare versions at matched loudness to hear what squashing actually costs.

What to listen for

At the shift from soft to strong in the Beethoven Fifth, hear whether the contrast survives; on the funk kit, whether the snare still has a point; in the quiet stretches of Le gibet, whether detail is still audible. An over-crushed master sounds bigger on first listen and more tiring on the second.
