How to normalize audio: Have you made some audio recordings on your computer where the background sounds, music and vocals are not leveled properly? The songs in your MP3 collection all have gods volume levels different from each other and listening to them with headphones is a risk for eardrums? These are no longer your problems from today.
Why? Simple, because I’m going to show you step by step how to normalize audio thanks to two free programs that in an absolutely simple and fast way allow you to solve any problem related to the volume and equalization of sounds in audio files. Interesting, right? So let’s not waste any more time and find out immediately how they work.
If you have made audio recordings that are not perfectly equalized, in which your voice and background music blend with other noises, and you want to find out how to normalize audio in cases like these, you can only turn to The Levelatora free program that analyzes all levels of audio recordings in WAV and AIF format and equalizes the sound in order to make them more “clean” and understandable.
To download it to your PC, connect to the program’s website and click on the item Download located in the center of the page. When the download is complete, double-click on it to open the file you just downloaded (LevelatorSetup-2.1.1.exe) and, in the window that opens, first click on Run And Yup (to authorize installation on Windows 7 and Vista) and then on Next. Then accept the conditions of use of the program, putting the check mark next to the item I accept the agreementand first click on Next for four consecutive times and then on Install, Next And Finish to finish the installation process and start The Levelator.
At this point, all you have to do is select the audio file to which to normalize the sound and drag it with the mouse into The Levelator window, the program will automatically process it and save the optimized version of the sound (with the suffix output in the name) in the same folder as the source WAV / AIF file.
If, on the other hand, you have to much more simply normalize audio in MP3 files to transfer to portable players or listen with headphones, the best solution for you is MP3Gainfamous free program that allows you to normalize the volume of multiple MP3 files at the same time without reconverting the original files and keeping their quality intact.
To try it, connect to its website and click on the item mp3gain-win-1_2_5.exe to download the program to your PC. When the download is complete, double-click on it to open the file you just downloaded (mp3gain-win-1_2_5.exe) and, in the window that opens, first click on Yup (to authorize installation on Windows 7 and Vista) and then on Next. Now, expand the entry Language Filesput the check mark next to the item Italian (to install the Italian language) and first click on Next and then on Install And Finish to finish the installation process and start MP3Gain.
In the window that opens, click on the button Add files or Add folderrespectively, if you want to add “bulk” mp3 files or entire folders of music tracks to the program and click on Normalize (Track) to start audio normalization in all files imported into MP3Gain. For best results, I recommend that you leave the target “normal” volume to 89.0 dB.
