Keep mp3 files volume constant

Page creation date :

summary

I don't care much because the volume of songs purchased from CDs and download sites sold in general is usually adjusted to keep constant, but if you distribute some CDs and personally produced songs on the Web, some CDs sold by the same person may have different volumes than other albums, and if you listen to other songs together, I think that there are times when you feel uncomfortable.

This section is limited to MP3 files, but we will introduce Tips using a software called "MP3Gain" to keep the volume constant.

substance

"MP3Gain" is distributed on the following site, so let's download it from the link.

If you want to download from the home site, click the link of "mp3gain-win-1_2_5.exe from the link destination page.

The right sourceforge page opens. If the file does not download, click the "direct link" link to download it.

If you want to download from Window Forest, click the link of "DOWNLOAD" to download the file.

After downloading MP3Gain, double-click "mp3gain-win-1_2_5.exe to run it.

Click the "Next" button because the installer starts.

Since you can specify the supported language, check "Japanese" and click the "Next" button.

Check the installation destination and click the "Install" button.

When the installation is complete, click the "Finish" button to close it.

If "Run MP3Gain" is checked, the MP3Gain application will start as it is.

If you want to start from the start menu, you can start it in the "MP3Gain" folder - "MP3Gain".

When you start MP3Gain, you will see a screen similar to the one shown on the right.

If the language displayed is English, select "Japanese" from the "Language" in the menu. (Please note that if you do not select Japanese at the time of installation, it will not come out.)

Next, keep the MP3 files you want to keep the volume constant in a folder. You can specify the files individually, but it is useful to specify the MP3 files in them at once by specifying folders.

MP3Gain sets the volume of the specified file to a constant level and then overwrites the file, so if you want to keep the original MP3 file, you need to duplicate the file.

Once you have prepared the file, click on the "Add Folder" button.

Select the folder you just prepared.

The list of MP3 files in the folder is loaded.

Then specify the volume. It is specified as "89" by default, but 89 is surprisingly low volume, and CDs sold in general are roughly around "95-97", so it's a good idea to specify a neighborhood.

Once you have set the volume, click the Track Gain button. Click to start adjusting the volume immediately.

It will take a while to complete. Once the conversion is complete, the MP3 file is already in an updated state, so you can exit MP3Gain.

This time, we used track gain to convert the volume of all files to a specified volume, but there are also "Album Gain" that increases or decreases the volume of all MP3 files by a certain value for the average volume from the MP3 files in the list, and "Constant Value Gain" to increase or decrease the volume of all MP3 files at a specified volume, so try using it according to your purpose.
