What Is M4A?
M4A is the file extension used for audio files in the MPEG-4 container format. It is commonly used for unprotected music downloaded from the iTunes store. The format is similar to MP3, but has better sound quality and smaller file sizes. M4A files are compatible with various media players and audio editing software.
What Is M4B?
M4B is the file extension used for audiobook or podcast files in the MPEG-4 container format. Like M4A, M4B files are typically encoded using AAC (Advanced Audio Coding), a lossy compression method. These files are often associated with audio content downloaded from the Apple iTunes Store, and they can contain chapter markers, bookmarks, and other features suitable for audiobooks and podcasts. Apple's iTunes and various media players support the playback of M4B files, making them convenient for listening to long-form audio content such as audiobooks.
M4A and M4B are both reliable and are among the most used audio file formats. But of course, they still got some differences that could be considered as their advantages over the others. Let us start with the first measurement - encoding method and format protection.
Both the M4A and M4B file formats are known to be under the MP4 codec which is encoded by Advanced Audio Coding or more known as AAC. The M4A file format is mostly used as the formats of tracks whereas the M4B is used for audiobooks that can be purchased from the iTunes store.
If you are using the iTunes application, we assume that you are aware that those files that the application has been protected by this DRM (Digital Rights Management) protection that is hindering the users from playing the files on unauthorized devices and even download those for sharing and file transfer. You should know that those files in M4A format do not have this protection. Those files in M4P (that are being used for iTunes and Apple Music tracks) are those with DRM. But you can convert M4P to the format without DRM protection.
To compare the M4A files with those in M4B format, the M4B format has the DRM and non-DRM versions (for audiobooks). Those that you are got from the iTunes stores are with this protection whereas those that you can easily find over the web are usually DRM-free ones.
Another point of comparison is the compatible devices that can handle M4A and M4B files. As initially discussed under the encoding method and format protection section, these file formats could be protected by the DRM protection. If those are with this protection, there would only be a limited number of devices that can handle the access of these files because the DRM protection is responsible for limiting the ability to play these files on unauthorized devices to protect the copyright ownership of content makers.
You can have these files streamed, accessed, or played on iOS devices such as iPhone, iPad, iPods, Mac computers, and more. Those that are not encrypted by the DRM protection can easily be played on any media player (VLC Media Player, Windows Media Player, etc.) and gadgets as long as the formats are supported by the device. In case you have a device that cannot support the playing of either M4A or M4B files, you can jump to the third section of this article to know about a tool that has the ability to convert M4A to M4B or even M4A to MP3 format (in case needed). Do you want to know some converters that can transfer M4A to MP3 format? We can give you more details.
The last point of discussion in the first part of this article is “Copy Protection”. As we have previously discussed, the same with the movie, videos, and TV shows that can be accessed and bought from the iTunes application, the files in M4A and M4B formats are as well protected by Apple’s FairPlay protection. Those in M4A are not protected. Those in M4P are the ones protected by DRM protection and can only be played on limited media players such as QuickTime player and iTunes application.
The same with M4A files (with DRM protection), M4B files are only allowed to be played on a selected number of devices. In order to remove this protection, there is a need for a tool that can do the job. This is what we are to discuss in the third part of this article. So, if you are curious to find out more about this application, you can freely skip the second part and read the third portion in case you want to.
