Sound normalizer
sound normalization
Since the audio was digitized, a noticeable difference in volume levels or loudness between different audio or video files began to be noticed.
What is amplification of sound?
Why does this difference or difference in audio volume or loudness occur between audio or video files after digitization?
The reasons are several and in general they are quite simple. The first is that in the days of vinyl records, since switching from one record to another took time, we generally didn’t notice much if there was a difference between them in terms of volume gain.
Neither were common users, without specialized preparation, who manipulated these vinyls. Today, on the other hand, any person using any software decides to take a CD and extract the audio using the parameters (bit rate, sample rate, etc.) that occur to them, almost at random.
And this capricious or random choice of audio settings generates a difference in quality in the long run and of course has a great impact on the volume of the audio, on the loudness of the mp3, flac, ogg, etc.
That is to say, nope, it is due exclusively to the differences that the original audio already contained, but to those that are introduced according to the settings to encode it into another format that occupies less space, such as an mp3.
This forces us to later use normalization as a method of reversing that disaster that amateur enthusiasts have introduced by encoding, without knowing what they are doing, the audio or video.
Mp4Gain is the ideal software to reverse and normalize all this in the main audio and/or video formats.
