Automatic batch audio equalization. S. Luca, Chisinau
- Track- MP3Gain calculates the volume level individually for each track. It then adjusts the volume of each track to the desired level. For example, there are 3 songs with a volume level of 86, 91 to 89 dB. If you apply the Track Type to bring them to the required 92 dB level, all of these songs will have a level around 92 dB.
- Album- The overall volume of the album will be adjusted to the desired level, but the volume differences between tracks in the album will be maintained. For example, there are 3 songs with volume levels of 86, 91 and 89 dB, the total volume of this album will be about 89 dB. If the desired level is set to 92 dB, and the Album Type is applied, MP3Gain will increase the volume of each of these songs by 3 dB.
- Constant- This mode is similar to Album mode. In it, the volume of all tracks is simply increased or decreased by a given number of decibels without any normalization relative to each other.
This article will be useful to those who have asked the question: “How and with what program to equalize - normalize the audio level?” If you have collected your music and audio collection by downloading one track at a time on the Internet, and are faced with such a problem as different volumes of audio files, some sound loud, others are quiet (for example, old retro records), then a small free program MP3Gain will come to your aid .
!Attention. This is not an analysis of audio correction and editing, it is just one of many ways to quickly get rid of headaches.
MP3Gain - to normalize the audio volume of MP3 files
The MP3Gain computer program allows you to increase, decrease and equalize the volume of both a single file and a whole batch of files (for example, in a music album). MP3Gain only works with the MP3 format, but if desired, you can install an extension (for example, to process AAC (Mp4) files), more details on the website http://mp3gain.sourceforge.net
The program is completely free and weighs about 5 Mb when unpacked, depending on the assembly and the additions included in it, such as locale, help and other extensions. On the website there are different versions in two versions, install (.exe) and portable (.zip). If you use install (.exe), then for Russification select Language filts + Russian when installing. You can also download from PortableApps.com an assembly with the Russian language installed (and a bunch of others) - http://portableapps.com/apps/music_video/mp3gain_portable
MP3Gain works very correctly and does not make changes to the encoding - decoding of the MP3 file, i.e. the quality of the musical fragment remains unchanged, only the sound volume is processed. The program interface is very simple and understandable; to work with a music file or a batch group of files, the user only needs to perform a few steps.
Add MP3 files to the program
- Set the desired sound level
- Start the sound change process
The program will do everything itself, automatically determine the average sound level of all files and correct quieter and louder files. I recommend reading a more detailed description of the program, its advantages and disadvantages at http://ru.wikipedia.org/wiki/MP3Gain
So, after you visited and read the Wiki, everything became clear to you and you can begin automatic batch audio equalization.
!Make copies of your audio files, just in case. The program does not have a function for saving corrected files; it immediately changes the original ones.
Check that there is something in Options there was a tick opposite "Changing Level Without Clipping". I hope you have studied Wiki in detail, you know what “Clipping” is and you understand in what situations and what problems its use can lead to.
Setting the volume level
By default, the “Normal” volume is set to 89 decibels (it's better to leave it unchanged). According to most experts, it is this number that gives the highest quality results in terms of normalization and elimination of clipping. If you wish, you can set the standard to any value from 75 to 105 dB. Make copies of your audio files and experiment to find the optimal value for you.
Modes Track Album Constant
Audio equalization process
1. Click the button "Add files to list" and select the files you need. If you click the button "Add folder" you can add all files located in the selected folder, and also if Add Subfolders is checked in Options, all folders inside the one being added will also be selected and files from them will be added to the list.
2. Optionally, you can click the " Analysis Track"and see what the volume of your source files is. And so, for quick alignment, you don’t have to do this.
If the track contains " Clipping", then the letter appears in the corresponding column Y, and the entire line turns red.
3. To normalize and equalize the sound, click the " Type Track", and be prepared to wait - depending on the number of songs, the process may take some time.
That's probably all about quick sound equalization. I recommend that those who opened this program for the first time do normalization once or twice as a test on several (3-7) audio tracks. AND Do not forget protect original files when working with copies.
For those who want to do more painstaking work
Do “Track Analysis” and check the box in the settings: Work only with selected files.
Select the files you need to edit and change the " Type Track" on " Constant"or in the top menu: Change level/Apply Constant... Using the slider, set the change you need.
Using the slider, you can increase the maximum (105 dB) volume level (the increase number is added to the standard). You can experiment with this value to achieve the optimal volume.
To evaluate the changes, listen to the files by right-clicking on the file and selecting " Play mp3 file"(if you listen to them on a portable player, copy them to it). If the volume is too increased, the song will hiss; you can cancel the edit result by clicking the right mouse button in the field with added files and select "Undo Gain changes" or in the top menu " Change Level/Cancel Level Changes" You can also try changing the volume again with different settings, slightly lowering the value of the constant for the problem file.
For those who constantly listen to music in an mp3 player, you are probably familiar with the problem with normalization sound different compositions after adding the compiled playlist. Either the sound becomes too loud, or on the contrary, it becomes so quiet that even increasing the volume does not allow you to enjoy the melody.
This problem also prevented me from listening to music comfortably for a long time.
And I started looking for a way to solve the problem of loudness normalization. Using an Internet search, I was able to find a simple solution in the form of the mp3gain program. It is also worth noting that the program can be used for free.
In addition to ease of use, the program is also good because it does not make any changes to the audio data. It simply changes the value of ID3 tags. Most programs (such as iTunes) and mp3 players understand this value and play the track with the specified parameters. So, the essence of the problem is clear, the tool has been found. Let's get started.
First, download the mp3gain program (you can download it from here http://mp3gain.sourceforge.net/download.php) and install it on your computer. The program supports different languages, including Russian; to change the language, click the Language menu and select Russian.
First you need to select a folder with files for processing, to do this, select the button Add folder.
After the files are downloaded, click the button Track analysis
Depending on the size of the tracks being downloaded, this procedure may take time.
The program will determine the volume of the files and calculate how much it is necessary to adjust the sound strength in the tracks. After the analysis is completed, you can bring the volume to one value simply by entering it in the field Volume standard
After processing is complete, all tracks will sound at the same volume. If you don’t like the effect of normalization, and there is a desire to bring everything back to its original value, then this is not difficult to do. You just need to select the item in the menu - Change level and press - Cancel level change .
That's all. We can only hope that the method I described in this article will help you too.
solve the problem of normalizing the volume in different music tracks and enjoy music without constantly adjusting the volume level in the player.
Here I just showed an example of how to work with the program. This doesn't mean you have to do it that way. For ease of demonstration, the maximum values were set. This can lead to significant distortion. Therefore, select values that are acceptable to you.
Especially for better assimilation of the material on working with the program, I made a video - how to make the volume of tracks the same:
Often new landowners are faced with the problem of an uneven plot: potholes, slopes, holes, etc. Many people think that correcting the situation will require a lot of effort and financial investment. In this article we will figure out how to level a plot of land in a country house for or a vegetable garden, and how difficult or easy it is to do it.
When to start
A house has already been built on the site, engineering and communication work has been completed, and it’s time to start arranging places for recreation, garden walkways, and some decor. The paths around the house will not only improve the appearance, but also protect against the pressure of the soil layer on the foundation, and along the pedestrian paths you can easily get to any corner of the site, even if the ground has been washed away after rain.
In order for all this work to be carried out efficiently, the site must be prepared by removing all possible irregularities on its surface. As for beds or lawns, a flat surface is simply vital.
With a flat area, firstly, water is used sparingly, and secondly, evenly. Otherwise, there will be insufficient moisture on the hills, and in excess in the pits, which can cause root rot.The most suitable period for leveling a plot of land is autumn; level areas need to be dug up and left until spring. During the rainy season and winter snow, exposed to temperature changes and moisture, the soil will settle significantly, become saturated with useful substances, and in the spring it will be ready for planting cultivated plants. 
What and how to level the area
There are several options for leveling a plot at your dacha, but first you need to carry out preparatory work: uprooting stumps, removing debris, large stones and boulders.
Manually
For manual work you will need:
- wooden pegs;
- a skein of twine;
- tape measure and gardening tools.
The hills are removed with a shovel, the top layer is laid aside. If plant roots remain in the ground, they are removed with chopping movements of a shovel. The holes are immediately filled up, taken from the hills. 
After the work has been done, they go around the entire perimeter with a rake, and then, so that the earth does not sag, they compact it with a roller. You can make a roller yourself: weight the barrel with crushed stone or small stones, close it and roll it over the surface of the ground.
After some time, the soil will still shrink; you will need to add a top layer and compact it again.
Did you know? Sandy soil, despite the lack of nutrients in it, has one valuable quality: due to its granular structure, it does not retain moisture, easily allows oxygen to pass through, and root rot in such soil has no chance of survival.
Before carrying out work, it is advisable to make sure that the soil on the site is suitable for growing crops. There should be at least half a meter of good nutrient soil (top layer).
Soil mixtures can be purchased in specialized stores; it is advisable to dilute clay soil with sand for a more uniform structure. 
Motoblock or cultivator
If the plot of land is large, from 5 hectares, then the best option for leveling the land on the plot is with the help of or. This treatment with the help of attachments eliminates unevenness up to 15 cm deep.
Important! After this procedure, it is advisable to treat the soil with steam. A simple steam treatment involves watering the soil with boiling water; the procedure destroys harmful microorganisms in the top layer, as well as weed seeds. For large areas, they order treatment with a steam machine, treat with sulfur and copper oxide.
They walk through the plot several times in different directions, and then use a rake to finally level it, at the same time removing plant debris and stones. In this case, you can also extend the level so that the final alignment is perfect.
Tractor
In the case of a badly neglected plot of land, it is advisable to order work. The machine’s bucket is capable of capturing and leveling layers of earth up to a meter deep. It is recommended to plow in two directions: along and across. 
Alignment Features
It cannot be said that some unevenness on the surface of the earth will negatively affect the yield, but planting and caring for crops is much more convenient and practical on level beds. They are easier to weed and loosen, and water is used more economically when watering.
Under the lawn
The attractiveness and well-groomed nature of the lawn directly depends on the smooth surface of the land plot. Due to the holes in which water will collect, the lawn will constantly get wet and the grass will rot at the roots; Lumps and mounds on the surface will make mowing the lawn much more difficult. Let's figure out how to level an area for a lawn with your own hands.
Using pegs and string, levels are set; in places that deviate greatly from the level, the layer is removed, covered with matting, and left in the shade. The depressions are filled with (pre-prepared) imported soil, and the tubercles are cut off.
When there is a small layer of nutrient soil, imported fertile soil is mixed with soil removed from the surface of the lawn. Heavy soil is mixed with sand and only 20% of the total composition is added. Important! If the lawn has large differences in the surface, then the top layer must be removed completely, not partially. It is not advisable to keep it under a canopy, covered for more than a month; during this time, the beneficial microorganisms in it will die without access to air.
Plot with a slope
Let's look at how to properly level a sloped area. To raise a large slope, unsuitable soil or sand left over from construction may be useful.
Equalize and equalize. Who cares?
S. Luca, Chisinau
The orthographic difference is obvious: in the unstressed position, the root is equal in words that are related in meaning to equal, identical, for example: uniform, equivalent, compare, anyway, as well as in the words alignment, equal, equal, equalization, plain; the root is equal - written in words related in meaning to even, smooth, straight, for example: level (hole), level (flower beds).
Accordingly, the word equalize should be used in the case when we are talking about two or more objects that are subject to equalization, that is, about making these objects identical: equalize in rights, equalize in weight, equalize chances; The word level is used with the meaning of making the surface flat, smooth: level the road, level the bed, level the ground.
How will it be more convenient
Which is correct - simultaneously or at the same time?
Y. Gratiy, Balti
Most dictionaries of the modern Russian language call both stress options correct. Several years ago, Evgeny Grishkovets played up the equality of both options in a unique way, calling his one-man show “Simultaneously.”
Some reference books consider simultaneous stress acceptable, giving preference to simultaneous pronunciation. But Joseph Brodsky in his poems used this adverb only with emphasis on the fourth syllable:
Let them not disturb us
on an autumn day.
It's not easy for us
because we are both flesh and shadow
simultaneously,
shadow and light together
think so
that we are not in the world...
So you can rightfully use the form that is closer to you. The main thing, as textbooks on speech culture warn, is not to allow pronunciation at the same time and not to mix it with the same thing.
temporarily.

We listen to music at home, at work, walking down the street with a player, we enjoy it while relaxing and chatting with friends. But music tracks have one peculiarity - they can sound at different volume levels and, replacing each other during playback, one will sound louder or quieter than the next. In some circumstances, this is disruptive, distracting, and even annoying. You can equalize the volume of mp3 files without losing quality with the free Mp3 Gain program.
Normalization of mp3 files
By default, the program takes a value of 89 decibels as the norm, which is considered to determine the highest quality result during normalization. The user can set any value in the range from 75 to 105 decibels and process mp3 files in three ways: “track”, “album” or “constant”. In the first case, these are any selected files, in the second, the album is considered to be the folder in which the mp3s are located, and in the third mode, the volume level of the tracks simply increases or decreases by the specified number of decibels. Mp3Gain implements the function of maximizing the volume level without the appearance of distortion - hissing, crackling, so-called “clipping”. Normalization of mp3 files is carried out without re-encoding tracks, so they do not lose their original quality.
