How to edit AAC tags?


AAC stands for Advanced Audio Coding. It's an audio codec that features a better audio compression than the well-known MP3 format. AAC audio files can have .aac, .m4a, .mp4, and several other extensions (depending on the container format). This codec is actively supported by Apple.

Like ID3 tags in MP3 files, AAC files offer some space for meta information like title, artist, track number, year, comments, genre, album. These tags are important for searching and sorting, they can be used to organize a music collection. Besides, most players nowadays read tags and expect files to have them.

To edit AAC tags, you can use a tool like mp3Tag Pro.

Step 1: Download and install the program.

Download mp3Tag Pro to a known location. Run the downloaded setup package and follow on-screen instructions to install it.

Step 2: Start the program. Select files to edit AAC tags.

Launch the AAC tag editor. Browse to the folder where your AAC files are stored. You can browse as usual, by double clicking folders to enter them and by double clicking '..' to exit a folder (or use the "Level up" button), or selecting folders on the left. Alternatively, click the folder icon in the address field of mp3Tag Pro to invoke a usual "Browse" dialog.

Select AAC files

Once you are in the correct folder, AAC files should be shown, like on the screen shot above. If mp3Tag Pro shows no files on your computer, but AAC files are there, click View and select the "Show files" submenu:

Step 3: Edit AAC tags.

Now you have various possibilities to edit AAC tags. mp3Tag Pro supports downloading tag information from FreeDB and Amazon tagging services, importing tags from a CSV file and other tagging methods. As our filenames already contain information about artist, titles and track numbers, we can do the following.

Select all files in the directory by clicking the "Select all" button, as shown on the first screen shot. Alternatively, you can press "Ctrl" + "A" on your keyboard.

Generate AAC tags

Click the "Generate tags" button. This will open a new window.

Extract AAC tags from filenames

Our filenames consist of three parts: Artist - Track number - Title. Let's tell the AAC tagger this in its format field in the left upper corner of the window. We type %A - %# - %T and choose to overwrite the existing tags. See results in the preview area.

Finally, click "Generate tags" at the bottom of the window to save the information extracted from filenames to AAC tags.


So, we have easily filled out three fields. If you know some additional information about the files, or want to add your comments, select all files again and type any information you want into the corresponding fields.

Edit AAC tags manually

Click "Save" to save changed fields into all selected files.

Both the above described methods can be used for up to 10000 AAC files at once. To select files in more than one folder, use "Scan subfolders" button near the address field of mp3Tag Pro.
