GAIN - Normalizing Audio

Many times, we wonder how and with what program can make the songs or audio tracks downloaded or recorded from various sources are a uniform volume. For those who do not know this action is called "Normalize" and This simple program that now I turn now to detail is very easy to get.

program called MP3Gain , is in English and it's FREE!. Donwload

Once we turn to install the progam. The first thing we will be this window:

choose the language with which we work. For this picad + Language in files and we will display a menu with all available languages. Click on the box and continue the chosen language.

Now we will go out the window where the program is located, we give next if that is where we to locate and browse to choose where the location ourselves. We would like to Install.

We will get a screen like this saying that the program has been installed and where they are:

We accept and continue.

We went to My Computer "C" Program Files ... MP3Gain ... open and see this icon:

I chop and send it to the desktop if you want to create a shortcut:

Once the deck is open and we will see this screen:

If the language that leaves us is not satisfactory for us, above all, we have the "language" where we can modify it as long as we find him selected in the installation.

Well now let's start with the real work. We see two options "Add files" or "Add Folder", the first option is to go file by file and choosing the second to add an entire directory. A good working method is to create a directory and put the songs you are going to record, then choose Add folder, this does not then you will become crazy looking. Say it is always more convenient to work moving the block with that little by little, we save time.

Once you add a directory will leave the songs on screen:

MP3Gain works in two modes and Album mode Radio mode. What does this mean? Radio mode is the use for albums or songs from different musical groups unrelated. In this mode the program calculates separately the appropriate level of each file. Album mode is to lower or raise the volume of a full album of the same artist and from the same source and we do not sound too good.

Now, as we see, have turned the other program options, such as songs from different albums and downloaded from different users are going to choose Scan Radio. The program will begin to analyze song by song and after the necessary calculations show the results in the fields Radio Volume and Gain.

The value in "Volume" shows us the overall volume of the song in decibels which is at the time of analysis, and in the "Gain Radio" increase or decrease the level that would be applied to obtain the value specified in the "Target Normal Volume" (red arrow). The "Target Normal Volume" is the volume that is going to be the song. We see some " Y "(Yes) in red in the" Clipping "... (Distortion) ... (blue arrow) ... this indicates that some of the passages of the song the level reaches 100% volume which will not be possible to increase the volume of that track in any case. While the "Clip Radio" remains without any problem and we have no distortion in this song, but if we would a Y in this paragraph have the problem distortion when I play.

Now, by way of example, I'll set up the level of the "Target Normal Volume" 90 to 95 and see how the "Y" we will shoot in paragraph Clip (Radio) which would give us distortions in the songs which go these "Y". This means that we have chosen an output volume than adequate for a proper hearing. I usually work between 89 and 90 and get a good volume, though sometimes I had to come down to 87 to keep out the red arrows on radio clip and therefore not distorted.

Well, after analyzing all the songs we choose the gain of Radio box and begin the process of "normalization."

As you can see the value in the column "Gain of Radio" as goes by the Standards will have a value of 0 for all files and the volume value be as close to that which we have chosen in the "Target normal volume." MP3Gain will never be accurate because it looks more rough but altering the original sound to a minimum. This small change will not involve anything as 2 decibels the human ear is very little discernible.

Well we have our songs ready to tune the volume up and ready to burn. But then and now ... How do I save changes? ... Nothing so easy as to give the exit button located at the bottom right so that the changes are automatically saved in the directory location of the songs that originally had created. And is.

should point out that many people tell me, "but if Nero does it automatically this normalization is not it?" Oh friends, but the Nero Standardization makes a call to pick, what is this?, It simply detects the highest peak volume recording together and after this peak detect it applies to all other tracks (songs) maximizing the volume to be lower. This process is called Maximize. This is not the best method to get all the songs sound at an even level, the most effective method is the one used MP3Gain which is the middle level Standardization (Average or RMS).
A little trick that some tend to use is, once normalized to average levels MP3Gain and when recording with Nero maximize the peak with it, or select the checkbox "normalize all audio files."

Nothing more. I hope this little tutorial you find it useful on occasion. because often, our audio files to add the video editing program, each have a different level, it is very annoying and very tedious to edit them one by one, correcting the audio volume ... since we first for this program and then edit said.
