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.
An MP3 file can be edited without transcoding. Cut, copy, paste, and volume change operations are provided; edits can be previewed, including a command that plays a segment without a selected region (previewing a cut) Audio normalization and pause detection; MP3 recording with ACM or LAME encoder (not bundled) Fast MP3 visualization
MP3 files usually use ID3v2. Other formats such as AAC and WMA use their native tag formats with a specially formatted tag entry listing the track's replay gain and peak loudness. ReplayGain utilities usually add metadata to the audio files without altering the original audio data.
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.

Library management: find, organize and rename music into particular folders and files based on any combination of audio tag values such as artist, album, track number, or other metadata.
