Normalize audio and video to improve loudness, tips to achieve better normalization.
Many years ago when the motion picture and recorded audio industry started, there were no problems with the volume of individual songs or individual video or movie broadcasts in theaters.
One of the main reasons is that each time one of these multimedia contents was produced they ended with a mastering which, among other things, took care of the volume level and in general the dynamics of the sound.
For some years now, the technical processes to encode the audio and also the image are not made by professionals but by people who download a program and start encoding audios and videos without having the equipment or training to do so.
On the other hand, especially in the area of video, there has been a boom in independent video production, many times carried out on cell phones that are not prepared and designed to record my video or high-quality audio.
In fact, even good quality microphones are not always used, but the phone’s own microphone is often used and sometimes at a considerable distance from the person who is speaking.
Later this video is edited more by intuition than by knowledge and this is how it is distributed on the net.
The same happens with music that is encoded, edited and recorded with more desire than knowledge.
All this has generated that when a person has several videos or several audio recordings, they immediately perceive that there is a great difference in the loudness of these videos or these songs.
Initially we talked about how before music was heard by people through radio broadcasters, for example, which had expensive hardware equipment, such as exciters and compressors, which were used to maintain a constant volume with a loudness dynamics that allowed it to be audible to a constant volume level.
The same thing happened with television and movie theaters.
The music that came out of the recording studios of the big record companies had careful mastering is where, among other things, they made sure that the output db was always in the correct range, the same can be said of television or film production companies that in addition to the equipment to compress the audio They also had professionals who took care of all this.
Today with the freedom for everyone to produce and share audio and video something that has been neglected You could say what is the standard of quality and loudness levels of video and audio volume.
That is why after many years of improvements the Mp4Gain has reached totally professional levels where music and video are treated and improved and optimized to reach the professional level in terms of quality and loudness of the audio volume.
Mp4Gain is also used to process audio files or video files to standardize the loudness of the volume, which is popularly known as normalizing the volume of the audio and normalizing the volume of the videos.
There is no other program that fulfills these functions at a professional level and at such a reasonable cost that anyone can have in their home.
It is no longer necessary to spend thousands of dollars to have professional compressors and exciters, but with a few tens of dollars anyone who distributes audio or video can determine that the sound of it is professional, standardized and perfectly audible.
