Updated October 2026 · Loudness and levels
The loudness war was a long trend of mastering music louder, using heavy compression and limiting to stand out on the radio and on CDs. Streaming normalization has reduced the reward for being loudest, but the habit of squashed masters remains, so choose your loudness on purpose.
Many people who listen to older recordings notice that they sound more open and dynamic than some newer ones. That difference has a name. The loudness war describes a long period in which mastering engineers pushed records louder and louder, often by squeezing out the quiet parts to lift the average level.
When listeners compared songs one after another on the radio or on a CD player, the louder one often seemed better. Louder songs jumped out, and labels and broadcasters rewarded them. Heavy compression and limiting were the easiest way to raise the average level, so the trend spread across genres.
Squashed masters lose dynamic range, so the drums hit less, the vocals feel less alive and the listener gets tired. Clipping and distortion became common, because the loudest peaks were pushed past what the format could handle cleanly. Many people still describe the result as fatiguing.
Streaming platforms adjust playback loudness, which removes much of the reward for being the loudest. A very loud master can be turned down, so its extra level no longer makes it sound better. This has encouraged mixes with more dynamic range, though the habit of heavy limiting has not disappeared.
Choose your loudness on purpose, rather than pushing for the highest number. A target that suits your content, with peaks kept below full scale, gives a clean result that survives playback adjustment. The loudness guide explains how to pick a target for each platform.
Loud, dense music is a valid style, and some genres are meant to be heavily compressed. The point is not that loud is bad, but that loudness should be a choice you can justify, rather than a race you lose by default.

Not entirely. Streaming has reduced its reward, but heavy limiting is still common in some genres.
In playback, very loud masters are often turned down by normalization.
No. A clean mix at a sensible target usually sounds better after playback adjustment.
A master with more dynamic range, where the quiet and loud parts keep their contrast.
