How to normalize mp3 files to play at the same volume
What could we understand by normalizing the audio volume level of an mp3 file or any other format?
A very technical definition would be to say that what is sought is to ensure that the upper volume level or the volume peaks of a song do not exceed certain levels.
That would be the answer that many people would give, but that would take us 20 years ago. When the normalizers were very simple and basic.
Today the technical explanation would be much more advanced and it would be something like this:
What a modern normalizer seeks is to ensure that the points with the highest volume level, also known as “peaks”, do not exceed a certain level, but at the same time they must not be below another level X.
In other words, the volume peaks of an audio file must not be outside a parameter, nor higher than one level X, but also not lower than another level X1. Which means that the peaks of a song will be very close to those of the other songs, with which we achieve that the sonority or loudness is very similar.
And if we are going to think about an even more efficient normalizing program, we could think that the lowest levels will not be outside of the x2 and x3 range either.
So we should never have to turn the volume knob to raise or lower the highest volume peaks of a song … nor should we turn the knob to raise parts of a song that sound very low.
In summary, the song (actually, all songs) will sound within a volume range, without falling below a certain level or rising from another level. What will make the activity of listening to music pleasant.
This is only achieved by Mp4Gain, which is also capable of doing all the important audio and video formats.
How to normalize mp3 files to play at the same volume? We hope that the brief explanation given above has been sufficient to achieve an adequate response.
And that helps to understand why some normalizers are definitely superior to others and more modern and efficient.
Because many people only think of volume peaks when thinking about a normalizer, but “sounding at the same volume” also implies that the lower volume parts are similar among all mp3s.
High and low volume parts will have similar levels.
