To encode with the proprietary encoder Nero: To encode with the open source encoder FAAC:įaac -q 80 -o part-01.m4b part-01.wav -w # with a MPEG-4 container(wrapper) Multiple programs exist that can encode to AAC. Split MPEG 4 compatible audio files (metadata repair will likely be necessary) into 10 minute intervals. Mp3splt -f -t 10.0 part-01.mp3 -o a MP3 by chapters/tracks (this method scans for silence and assumes them to be chapter/track marks, splitting them on those marks - these settings are generalized and will likely required further adjusting to work): Split a MP3 files into 10 minute intervals: Split a wav file ( wavsplit AUR can do this (untested)). MP4Box -cat track-01.aac -cat track-02.aac… disc-1.aac Join MPEG-4 compatible audio files (AAC, AVI, MP3…): Sndfile-concat track-01.wav track-02.wav… disc-1.wav # or more easily They can be concatenated or split as desired. (If no splitting of concatenation will be required, files can be directly encoded to AAC with a MPEG-4 container.)Īudiobooks parts are typically saved in about one hour, ten minute segments (usually the time extent of a audio CD). If the audiobook is a audio file, various programs can decode it. A common way to extract audio from a CD to WAV-formatted files is: If the audiobook is a disc media, various digital audio extraction utilities are available. The audio source file(s) will either need to be extracted, if a disc media, or to be decoded, if an encoded file. gpac - multimedia framework for manipulating MPEG-4 media.neroaacenc-bin AUR - proprietary AAC encoder.m4baker-git AUR - GUI program to combine numerous AAC-encoded audio files into a single m4b file with a chapter index.Multiple tools are available to help create audiobook files.

The basic process is this: the audio source is decoded/uncompressed (it is usually preferable to have a decoded audio-only file, as this will simplify the concatenation/splitting of files later and prevent mixing of metadata tags) after this, the audio files are encoded to the AAC format - with a MPEG-4 container last, the chapter index and audio information tags are added. The chapter index uses the Quicktime standard.

m4b) and two, it has a chapter index added to the metadata. The two differences are: one, it is wrapped in a specifically-named MPEG-4 container (. To create an M4B audiobook that supports chapters and bookmarking from a list of MP3 files, just keep reading.The purpose of this section is to detail a process to create an iPod-friendly audiobook from digital media using Linux native tools.Īn audiobook designed for iPods is largely the same as a MPEG-4 audio file - it contains both an audio stream and information about that stream (metadata). Note: In fact, this method saves yourself the trouble of converting them to M4B format, but doesn't change the MP3 files themselves. Then the MP3 list will be moved to the Audiobook section of iTunes. On the popup window, go to the Options tab, switch media kind from Music to Audiobook and click OK. Right click the mouse and choose 'Get Info', click 'Edit Items' on the prompted dialog box.

Select all imported MP3 files via holding down the Ctrl key for multiple selection. Alternatively, just drag and drop them into iTunes. Launch iTunes, go to File menu > Add File/Folder to Library to import your MP3 files. Actually, you're able to move the MP3 list to Audiobook section in iTunes without converting MP3 to M4B. As you know, MP3 files will be imported in the Music section by default.
