How to put your mp3s with the same volume and avoid volume increases between song and song

EThe other day I told you how annoying it is to be listening to music with an MP3 player and that suddenly when changing songs increase the volume enormously. If the change is very abrupt, it can even damage our ears since there are players that are capable of generating a great power output and in any case it is not advisable to subject our ears to such a rate of auditory stress.

TIt can also happen that you record a CD with a compilation of your favorite music and that when you put it at a party you have to be there all the time turning the volume up or down depending on the theme that sounds as the output intensity varies. This, like the previous example of the MP3 player, is due to the fact that the audio files (mp3) are recorded at different output intensities and therefore each one sounds at a different volume regardless of whether you change the volume or not. on your player.

PSo that this difference between the strength with which the different songs sound does not continue to bother you, what you have to do is normalize the sound of all MP3. Normalizing the sound is simply putting all the files with the same output level and therefore all the songs will sound at the same volume. This way you no longer have to go up or down the music after each song.

Un free program to normalize MP3s is MP3 Gain And it is also very easy to use and you can put it in Spanish. You can read the MP3Gain installation manual that I published the other day here in VinagreAssino.com. When you have it installed we can start with this mini manual to put all your music at the same volume and forget about those uncomfortable annoyances. Remember that MP3 is free and that you do not have to pay to download or use it, so you have no excuse for your MP3 to continue playing each one with different volume.

Si already have MP3Gain installed and you have put it en español Let's see how to normalize the audio of your songs.

1º) Open the program, a window will appear in which you have to look at the three fields indicated in the following image.

2º) The two fields above, «Add File (s)» and «Add Folder» allow us to add the files one by one or add a complete folder to normalize the audio of all the mp3 files contained in it. The other field called "Normal Volume Target" allows us to modify the output intensity of the MP3. The more decibels (dB) we put the louder the songs will sound later. The program sets "89,0 dB" by default and you can raise or lower this figure at will, but before doing so, think that if you raise this figure too high and you are in the habit of listening to your music with the volume of your player turned up, you can damage your ears. As stated on this page about hearing loss, the harmful effects of noise (from a legal point of view) start from 85 decibels (dB). So do not raise this figure too much, for the tutorial I am going to leave it at the default value «89 decibels» but remember that It is NOT good that you use your player at full volume.

3º) In this case we will see how to normalize all the themes in a folder at once so that you click on «Add Folder». A window called "Search for folder" will open in which you will have to locate the folder that contains the files you want to normalize. When you have found it, click on "Accept".

4º) Now you will see the selected mp3 files in the MP3Gain window. To normalize the sound we must first analyze the audio tracks that we have added. To do so, click on the button «Analyze Track» and the analysis process will begin.

5º) When the process is finished, the result of the analysis will appear on the screen. If the song is below the volume you have selected, a positive track gain will appear and if it is above it will be negative, in any case the program will raise or lower the volume of the songs until they equalize (normalize them).

If you look at the image there are a couple of themes that have a Red "Y" under the column "clip (Track)" this indicates that due to the increase in intensity that these specific songs are going to suffer, some distortion may occur at the points in the song where the volume reaches its maximum intensity. In principle, this problem does not usually bother too much, and many times it is not noticed, but if you prefer, lower the figure in the "Normal Volume Target" box and analyze again.

6º) When you are done click on the "Track Gain" button and all songs will be turned at the same volume.

Y with that you are done. If after playing the songs you think that the sound has been too weak or too loud, change the output decibel value and go back to point four of this tutorial. I hope that from now on you do not have frights listening to your favorite music and be careful with your ears, do not crush them they are for life. A sour greeting.
