Normalize the volume of your audio files for free with mp3gain

Listening to music in MP3 format has become a common trend for many years, since they are files that have enormous versatility and compatibility with all types of devices. In the same way, there are many compatible softwares available to be able to treat them, either to edit them, cut them, convert them, join them … and even normalize the volume.

And it is that the main problem that we can find when listening to music in MP3 is, precisely, the normalization of the audio. This is something that can happen to us, especially if we have obtained the files from different sources, which can cause some songs to be heard louder than others, which becomes quite annoying when playing them.

This problem can be frequent when we play a playlist on our player and we notice how the quality and volume of each song varies as we go from song to song. This leads us to constantly having to adjust the sound of our player. To solve this problem, we can use a program like MP3Gain, capable of normalizing the volume of MP3s, and about which we will talk next.

MP3Gain solves MP3 volume problems

MP3Gain is a free and open source program that analyzes and adjusts our MP3 files to ensure that they all have the same volume . This application will be in charge, through a statistical analysis, to determine how loud the file sounds to our ears. In this way you can analyze and normalize files to the same volume, and more importantly, without loss of quality . This happens because the program adjusts the MP3 file directly, without the need to decode and re-encode.

Once we execute the program, its main menu appears with an interface that, although it has a slightly obsolete design, is relatively simple and easy to use for almost any user as soon as they experiment with the different elements that compose it.

Add files to your interface and analyze tracks

The first thing we must do is start adding our MP3 or M3U files in the main menu. This is as easy as dragging and dropping our files onto the interface. We also have the option of clicking on the “Add File (s)” button from where we can add songs by selecting it from the file explorer. Similarly, we can add complete folders from the “Add Folder” button. These files are added as a list on the main screen and can be sorted by path, volume, album, etc.

Once we have added all the sound files that we want to normalize, we click on the «Track Analysis» button. In this way, the program is in charge of analyzing the files and will generate a report on the current volume level of each one of them. The value that appears to us is important that we keep in mind, in case, for any circumstance, we want to cover the volume to its original state.

Just above the list of songs we can select the preferred volume value, in the “Target Normal Volume” section. By default, it is set to 89.0 dB. Therefore, in the result of the analysis we will see the volume at which the files are and next to it the variation that MP3Gain will make to normalize them to the volume that we have established.

Normalize audios with a simple click

Once we have selected the volume to which we want to normalize our files, just click on the “Track Gain” button to start the process. Once finished, the new established volume will appear, so we only have to play the tracks to check if the volume is correct or is heard too high or low. For this we can double click on any song and play them with the desired player that we have installed.

In the event that we are not satisfied with the results obtained, we can provide a new level in “Target Normal Volume” and click on “Track Again”.

Conclusions: is MP3Gain worth using?

MP3Gain is a program that works well and requires a low amount of system resources for its use, fulfilling its purpose satisfactorily. It is fast in the process, although this is something that depends on the number of files that we are going to normalize. As it is a simple program, it may be too simple for more advanced users and lacking in options. For all other users it is a good way to normalize the volume of our songs, being especially useful to normalize an entire folder with the MP3s that we want to burn to CD.
