Also you can set Media Converter to delete source file after conversion and preserve original folder structure, when doing batch conversion. Finally, you should select the output format and sound quality. In M4B dialog box, choose format settings for the final tracks. Depending on quality you need, select bitrate, sample rate and the number of channels. You will probably lose some audio content if you choose mono option. You can choose what sample rate you want to use. 44.1 kHz (or 44100 Hz) is a sample rate used by music CDs. Less than that and you'll start to hear the loss in quality. You can choose a bit rate you want to use.

Once output settings are customized, you can go to the final step - transcoding.

Q: What is MP3 ?

A: MPEG-1 Audio Layer 3 or MPEG-2 Audio Layer III, more commonly referred in as MP3, is an audio coding format for digital audio which uses a form of lossy data compression. Its lossy algorithm was developed in 1991. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players. MP3 is an audio-specific format that was designed by the Moving Picture Experts Group (MPEG) as part of its MPEG-1 standard and later extended in the MPEG-2 standard. It is a method in store good quality audio into small files by using psycho-acoustics in order in get rid of the data from the audio that most of the humans can't hear.

Q: What is M4B ?


A: M4B is a file extension for an MPEG-4 part 14 audio layer audio book container file format used by iTunes. An M4B file is very similar to an M4A file but specified for audio books. M4B files support metadata for chapters and bookmarking on supporting players and most commonly uses AAC (Advanced Audio Codec). Audiobook and podcast files, which also contain metadata including chapter markers, images, and hyperlinks, can use the extension .m4a, but more commonly use the .m4b extension. An .m4a audio file cannot 'bookmark' (remember the last listening spot), whereas .m4b extension files can.

M4B is not as common as M4A though they both are MPEG-4 file types. If you like reading and always purchase audiobooks from Apple’s iTunes Store, you’ll find it frequently since it features that it allows listeners to remember the last listening spot instead of repeating the files from the start, whereas M4A extension files cannot. This is always considered as its advantage when we play it on authorized computers or Apple devices. But given that you want to listen to the M4B audiobooks anywhere and you don’t have a compatible multimedia player, converting M4B to MP3 is one of the ways-out since MP3 is the most popular audio format. Read along to know the best converters that you can rely on.

4 Apps that can convert M4B to MP3

Convert M4B with online converter tool

Many online converter tools provide people with this feature and Apowersoft Free Online Video Converter is one of them. It allows to convert videos and audios to any format available on its intuitive user interface. The high processing speed and almost lossless conversion maximumly save our time from hours of waiting and keep the quality similar to original files.

Note that this tool is useful only when the network connection is available.

VLC media player

Using VLC to transcode M4B to MP3 is also a solution though it’s a multimedia player known to common people. It runs on different platforms, for example, Windows, Mac OS X, iOS, Android, etc. If you just want to listen to the audiobooks on the go without any further re-encoding, you can just install the correct version of VLC media player. Read below detailed instruction if you insist on converting files with it.

Open VLC on your computer, hold Ctrl and press R on the keyboard and the “Open Media” windows will open. Tap on “Add” to insert your M4B file then press “Convert/Save”. A pop-up window will appear, drop down “Profile” then select “Audio – MP3”. On the same window, click “Browse” to select an output folder and finally click “Start”. VLC will then convert M4B to MP3 and save it on your PC.

The file conversion takes a lot of time. Also, some files are not recognised because of compatibility issues.

Use iTunes to convert M4B files

iTunes will also be one of our options as it can handle basic transcoding jobs if you arre using a Mac. To use iTunes as an M4B to MP3 converter, you just open the program and add your M4B file.

The audiobooks will then be created as an MP3 file.

Audacity M4a To Mp3 Converter

As what we have revealed at the very beginning, M4B is less known to people than M4A. When we buy audio files from iTunes Store, we find most of them are saved in M4A format and audiobooks are in M4B. Actually they are both a part of MPEG-4 format used for storing compressed audio/video. M4B is encoded in AAC coding only while M4A is in AAC, or Apple Lossless Audio Codec. Therefore, M4B is not as widely supported as M4A.
