Normalize audio
What does normalize audio mean?
The volume of sound is measured in decibels and a video or a song, that is, the audio can have more or less volume.
On the one hand we have that the audio or video file already has a “quantity” or a volume gain. That is, there is an initial volume level.
On the other hand, we would have the volume that we would assign to the amplification of our audio player.
In this case, for audio normalization we will refer to the input volume level or gain.
What happens if an audio file has noticeably lower gain? Well, it will sound at a lower loudness unless we manually modify the volume knob, which is annoying and inconvenient.
That is why the idea is that the volume input gain is optimal. Without distortion, but at a good volume.
Mp4Gain is the best software to perform this function, it is not limited to mp3s and even performs it on video files. Additionally, it can be used as a converter since regardless of the format of the input file, we can choose the format we want the output file to have.
For example if our input file is an mp4 video, we can choose to get an mp3. Thus we will have extracted the music, we normalize it and we obtain only the audio in an mp3.
Mp4Gain has many very useful functions to improve the audio quality of your songs or videos.
