Lautstärke-Normalisierer

Everyone knows it: a podcast where one speaker whispers and the other shouts. A voice recording so quiet you crank the slider to the max - only to fall out of your chair at the next clip. Inconsistent volume is one of the most common reasons audio sounds unpleasant. The Volume Normalizer smooths exactly that and lifts your file to an even level.

Two modes are available for different purposes. The standard mode uses EBU R128 normalization, the loudness standard from professional broadcasting. It brings the perceived loudness of your file to a consistent level without destroying the dynamics - just right for podcasts and music that should sound equally loud everywhere.

The Maximum volume mode works dynamically and specifically raises quiet passages. That is the right choice when a recording is too quiet overall or has big loudness differences - for example a voice recording where the speaker was sometimes closer and sometimes further from the microphone. Quiet passages become audible without loud spots clipping unpleasantly.

Normalization runs server-side with a professional audio tool that analyses the loudness and calculates the right level. That is more precise than simply turning it up, because it goes by perceived loudness, not just the raw peak level. Files up to 100 MB are processed, and the result is an MP3 file you can play everywhere.

Before download you listen to the result right in the built-in player and compare mode and file size. So you notice at once whether the sound is now pleasantly balanced. Happy with it? Download the file or file it in your archive with one click. Your file is processed only for normalization and not stored permanently.

The Volume Normalizer belongs to the audio family at Werkzeu.ge. If you want to merge several recordings first, cut out a section, or switch to another format, the right tools are right next door - all in the same browser and without an account.
