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

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

So that this difference between the strength with which the different songs sound does not continue to bother you what you have to do is to normalize the sound of all MP3s. To normalize the sound is simply to put all the files with the same output level and therefore all the songs will sound with the same volume. This way you will no longer have to go up or down the music after each song.

Now there has been a wide discussion about the volume in the videos. The truth is that YouTube is accused of ending the dynamic range … but to be honest I still listen to many YouTube videos with parts where the volume level is still very low and therefore, it is still necessary to use the Mp4Gain . But let’s continue reading what the ultra critics of YouTube say that accuse, without reason according to me, of matching all volumes:

The elders who once had the Volume Wars in this place count:
They were not our imaginations! The average volume of music albums has been increasing over the past three decades. The full explanation is in this article: The Loudness Wars: Why Music Sounds Worse. There it is told how the “war for the attention of the disc jockeys” of the radios of the last century led to an endless spiral of “let’s raise the volume a little more, so that it attracts more attention when I put it”, “a a little more »,« a little more »… This effect was later extended to digital MP3 players, where if after a few seconds between a song and the next one the second one sounds louder, it seems that« you hear best”. The result is an absurd war of more and more forced volume in each song, which in the end has produced that details and quality are lost in commercial music.
Now that fight without quarter seems to be over, as they explain in detail in this article: YouTube has just put the final nail to the coffin of the wars of the volume in Production Advice.
As he has analyzed the latest videos of great successes, they have been normalized by a kind of magic wand on YouTube, so that they all sound apparently with the same volume, although they come from radically different sources and with a greater range of volumes.

So eliminating the volume of the equation, the new game will consist of increasing the dynamic range of music, that is, the differences between the quietest and quietest moments and those of the highest volume, something that can be done elegantly by providing great moments acoustics as many artists have demonstrated for decades.
