Currently the most popular and used audio format is MP3, both for use on computers, mobile phones or other devices that we use to listen to our favorite music. Its main problem is that these files have been created and encoded in different ways, so their quality and volume can vary considerably, something that we will notice when it comes to playing them.
The way in which we can obtain our MP3 files are various, so it is likely that the way in which they have been encoded are different. This can affect not only the quality of the audio track but also its volume. It is certainly quite annoying to have to manually adjust the volume when we go from song to song. That is why today we are going to talk about audio normalization and what programs we can use for it.
What is normalizing audio?
If we are users who like to listen to MP3 music, it is likely that on more than one occasion we will have noticed how the quality and volume of each file varies depending on its encoding, which causes us to have to adjust the volume between the tracks due to to that they have different degrees of loudness. To help solve this problem, there are programs with which we can perform a normalization of the audio, so that all the MP3s that are part of the same playlist are played at the same volume and it is not necessary to have to adjust it manually between song and song.
Programs to normalize the volume of MP3s
If we are looking for a program that allows us to normalize the volume of our entire collection of MP3 files, we will tell you which are the most recommended that we should try.
