ffmpeg-normalize – open-source utility to normalise audio files in batch processing using Python and the FFmpeg framework; EBU R 128 Normalizer – component for the freeware player foobar2000 to analyse and normalise audio files during playback
ReplayGain is a proposed technical standard published by David Robinson in 2001 to measure and normalize the perceived loudness of audio in computer audio formats such as MP3 and Ogg Vorbis. It allows media players to normalize loudness for individual tracks or albums.
Before loudness normalization, one song in a playlist might be quieter than the rest, so the listener would have to turn a volume knob up to adjust the playback volume. [4] Depending on the dynamic range of the content and the target level, loudness normalization can result in peaks that exceed the recording medium's limits, causing clipping.

MP3Gain is an audio normalization software tool. The tool is available on multiple platforms and is free software. It analyzes the MP3 and reversibly changes its volume. The volume can be adjusted for single files or as album where all files would have the same perceived loudness. It is an implementation of ReplayGain. In 2015 Debian and Ubuntu ...
By modifying the global gain field of each frame of MPEG audio, the volume of that frame can be modified without altering the audio data itself. This allows for rapid, lossless MP3 audio editing that does not degrade the data from re-encoding. mp3DirectCut provides audio normalization and pause (silence) detection, and can split long recordings ...
