The resulting file will have chapter headers intact. Or you can write the file to unencrypted. You can then use mpv to listen to the file: It can be a laborious process to convert and Audible book format - article.Ī much easier way is to use this script to retrieve your activation bytes from a downloaded Audible audiobook - link.

The chapter index will need to be converted to the Quicktime standard (though MP4Box will recognize both chapter index standards when importing, it imports using the Nero standard). To merge the chapter index file in one step along with the audio file and a container: The Quicktime standard looks like this (thousandths of a second can also be added. There are two standards for chapter indexes: one, the Quicktime standard and two, the Nero standard. The chapter index will need to be written as a text file before being merged into audio file. Because of this the resulting media will be able to play on iPods and iTunes as expected. Though MP4Box is typically seen used for video files it has the ability to add chapters while not introducing a video stream. Note: mp4chaps will complain about not seeing a video stream when attempting to merge the chapter index with the -import option (a bug should probably be filed). NeroAacEnc -q 0.7 -of part-01.aac -if part-01.wav 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 (. 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).
