Although the standard is now formally known as ReplayGain, it was originally known as Replay Gain and is sometimes abbreviated RG.

ReplayGain is now supported in a large number of media players and portable media players and digital audio players. This avoids the common problem of having to manually adjust volume levels between tracks when playing audio files from albums that have been mastered at different loudnesses. It allows players to normalize loudness for individual tracks or albums. ReplayGain is a proposed standard published by David Robinson in 2001 to measure the perceived loudness of audio in computer audio formats, such as MP3 and Ogg Vorbis. Since it is the data itself that is modified, MP3Gain does not require special support from players. The way MP3Gain works actually has a very strong benefit.

Likewise, if you subtract 1 from this field, you multiply the amplitude by 2^(-1/4) = 84 % = -1.5 dB.

If you add 1 to this field in all the MP3 frames, you effectively multiply the amplitude of the whole file by 2^(1/4) = 119 % = +1.5 dB.

When an MP3 player decodes the sound in the frame, it uses the global gain field to multiply the decoded sound samples by 2^(gain/4). This field holds an 8-bit integer which can represent values from 0 to 255. In each frame there is a "global gain" field. Each frame represents a fraction of a second of sound. The MP3 format stores the sound information in small chunks called "frames". Here's the technical reason on why it's lossless (despite operating on the data itself), and also why the smallest change possible is 1.5 dB: Another difference with MP3Gain is the fact that it can only adjust physical volume in 1.5 dB steps. With MP3Gain, the loudness adjustment is done on the data itself, albeit in a lossless/reversible way. However, with most other formats, the necessary loudness adjustment of ReplayGain is stored as metadata, thus leaving the encoded results alone. MP3Gain is an implementation of ReplayGain, supporting Track mode and Album mode. This way, you don't have to keep reaching for the volume dial on your MP3 player every time it switches to a new song. It can then adjust the MP3 files so that they all have the same loudness without any quality loss. MP3Gain is a program that analyzes MP3 files to determine how loud they sound to the human ear. Don't worry, this can be easily fixed with a nice little program called MP3Gain.

I'm pretty sure that most of you have faced the following situation: you have a large collection of MP3 files from different sources (cd's, online purchases etc) but when listening to them, you find out that they play in different volumes, making listening to them pretty annoying. The silence will be remove from the resulting files.Normalize The Volume Of Your MP3 Files With MP3Gain The following command will split FILE.MP3 using a silence threshold of -30 dB, a minimum silence duration of 1 second. (2) mp3splt: Utility for mp3/ogg vorbis splitting without decoding/lossless NOTE: You can use a negative gain value as well. If you want to increase the volume by, say, 2 dB, you can use: To manually change the gain, you can use the -d option to modify the dB gain by a floating-point number above or below the default volume. If you want to ignore the clipping warnings altogether, use the -c option.

I have also noticed that the utility will warn of clipping far more frequently than clipping actually occurs, so feel free to take the clipping warnings with a grain of salt and adjust a bit past what mp3gain considers safe.

To install MP3Gain:įor the first test, you might want to let mp3gain try to automatically adjust the gain based on its analysis of the current songs’ volume. What mp3gain does is change the file’s metadata to tell your MP3 player to increase or decrease the gain in a way to achieve a consistent amplitude/volume between MP3s. Mp3gain does not re-encode the files or make any irreversible changes to your MP3s audio data.
