Is it possible to Normalize or boost the audio of an mp4, avi, mpeg, 3gp video, etc?
Not only is it possible to do it with Mp4Gain, but it is desirable and necessary.
And what is achieved is a dynamic normalize or dynamic boost, which means that the loudest or loudest parts go down to an optimal point and the quieter or less noisy ones go up to an optimal point as well. That it conserves the dynamics, but within a suitable margin.
Because having videos of any format, be it AVI, MP4, MOV, 3GP, etc. that have unbalanced audio and incompatible with other videos, is something that nobody wants.
Mp4Gain can balance, boost, enhance, the volume of the most popular video formats.
And it does so with a dynamic boost, which improves the lower parts, making them more audible and controls the loudest making them more controlled, without uncomfortable peaks or falls or valleys that are too quiet.
It is exactly what is achieved in a professional cinema film, that everything is audible and that nothing is annoying because it is loud or with unpleasant peaks of loudness.
It is also the same thing that is obtained in a radio station of Radio F.M. or on a television. You never have to turn the volume up or down with the knob, because the sound is bumpy and unbalanced.
Of course, Mp4Gain can not only boost or normalize the volume of videos, but it can also boost or normalize the volume of audio files.
You can even convert them to each other, for example extract the audio from a video and at the same time boost or normalize it. Or you can convert one audio format to another format and boost and normalize the volume.
