Some years ago, I started a desperate race to equalize, level, normalize or boost the volume of the mp3s.
At the time that people downloaded dozens or hundreds of mp3s, it was quite apparent that there was a problem with the volume.
And that problem needed solution.
The first normalizers
Initially, normalizers emerged in a naive way based solely on volume peaks. Which produced an unsatisfactory result.
Little by little, they began to have new ideas and new approaches to face this disparity in volume levels that affected mp3s in a very notorious way.
REPLAYGAIN
The idea of replaygain came up, which gained a lot of popularity. But he had his weak points. nor was it entirely efficient and satisfying.
In addition, with the passage of time, other audio formats emerged.
None have yet fully competed with mp3, but genwro that programs like Mp3Doctor were able to normalize other audio formats as well, not just mp3.
THE YOUTUBE BOOM AND THE VIDEO
And then the video had a boom (this boom is here to stay) and little by little, with the passage of time, people began to get used to a new format, mp4.
BUT the same volume issues soon arose in the mp4 audio as well as the major video formats.
Mp4Gain arose to normalize the volume level of the main audio formats but ALSO in the main video formats.
You can normalize the audio of an mp4, normalize the audio of an avi, etc. using Mp4Gain.
In fact it is the only software that is capable of doing this.
Little by little, as the video becomes more and more a central guest on the web, people will use the Mp4Gain more and more to maintain their volume levels without increasing or decreasing.
It even offers other functions like equalize, modifying the pitch without altering the tempo and vice versa.
It is a fact that mp4gain is the only and central program that has all these functions and the one that is being used by amateurs and professionals.
You can normalize the audio of your mp4s with Mp4Gain.
