Booster Volume

Loudness Enhancer

Perceived loudness tracks the average level of a signal, not its peaks. This tool raises the average by compressing hard and then applying makeup gain, so audio sounds substantially louder even when its peak level has not changed. It is the technique behind loud commercial masters.

The trade you are making

Compression reduces the distance between the loudest and quietest moments. Once that distance is smaller, you can raise the whole thing without the peaks hitting the ceiling. The average level goes up, and average level is what your ears interpret as loudness.

The cost is dynamic range. A drum hit that leapt out of the mix now sits at a similar level to everything around it. On a train or in a car this is a clear win — the quiet parts stay audible over the noise. On good headphones in a quiet room it flattens music that was more interesting before.

This is the same trade described in what is loudness, and it is why streaming platforms now normalize playback rather than rewarding louder masters.

Frequently asked questions

Is this the same as volume boosting?

No, and the difference matters. Volume boosting multiplies everything and runs out of room at the peaks. Loudness enhancement reshapes the dynamics so the average can rise further than the peaks would otherwise allow.

Why does my music sound flat after this?

That is the compression working. Reduce the amount — the goal is usually the least compression that makes the quiet parts audible in your environment.
