Steps on how to convert MP3 to M4B:
1. Add the media files to convert.
The first step is to select media files to convert. Run Audio Transcoder and use Folder Explorer to browse files you want to convert. Then select a file in the File List, drag it to the Drop Zone and drop it there. Optionally, Audio Converter allows you to edit tags of any selected file in Drop Zone.
Once files are selected, the next step is to select the output settings in Converter.
2. Select the output settings.
The second step is to select an output settings. To begin, select a folder for output and choose an action to be executed if an output file already exists (create a new file, overwrite or skip existing file).
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.
3. Start to convert any audio files to .m4b
Click Convert button to start to transcode music into any audio format you desired. A conversion dialog will appear to show the progress of data conversion. If you want to stop process, please click Stop button. After conversion, you can click an Output Folder button to get transcoded files and transfer to your iPod, iPad, iPhone, media player or hard driver.
During the turning music into m4b, you can change priority of the process or set an automatic event to be executed when the conversion is over. After the conversion has finished, you can find your converted files in the output folder you specified.

Q: What is MP3 ?
Open Source Audio Transcoder
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.
