[-i filelist] outfile [@chapter_1@ infile @chapter_2@ ...]
-a author set book author
-c 1|2 number of channels in audiobook. Default: 2
-C file.png cover image

-E template make each file a chapter with name defined by template
%N - chapter number

-q quiet mode (no output)
-r rate sample rate of audiobook. Default: 44100
-s skip errors and go on with conversion
-t title set book title
-v print some info on files being converted
Attributes for -a and -t arguments (author and title) should be in UTF8.
Only jpeg and png are supported as cover page format.
Valid sample rate values:
8000, 11025, 12000, 16000, 22050, 24000, 32000, 44100, 48000
Chapters could be set either by chapter markers in file list or by
treating each source file as a chapter. In former case chapter name is
provided by user and should be enclosed in '@' characters to distinguish
it from file names. e.g.:
abbinder book.m4b '@Chapter 1@' track01.mp3 '@Chapter 2@' track02.mp3
Chapter names in the latter case are generated for each input file and
may contain some escaped sequences that would be expanded when creating
a chapter. Template is provided as argument for -E switch.
Available sequences:
%N - number of chapter, starts from 1
%a - value of 'artist' tag from source file
%t - value of 'title' tag from source file
So previous example could be rewritten like:
abbinder -E 'Chapter %N' track01.mp3 track02.mp3
== Examples
Convert one file to m4b
bash$ abbinder book.m4b myfile.mp3
Convert several files to mono m4b with sample rate 8000
bash$ abbinder -r 8000 -c 1 book.m4b myfile.mp3 myfile2.mp3
Convert all mp3 files in directory and set author, title and cover image
bash$ find ./dir -name '*mp3' > list
bash$ abbinder -i list -a Author -t Title -C ~/cover.png out.m4b

bash$ abbinder book.m4b '@The very beginning@' 01.mp3 \
'@In the middle of something@' 02.mp3 \
'@Ashes to ashes and dust to dust@' 03.mp3
Convert several short-stories files and make each of them a chapter
bash$ abbinder -E '%t' story01.mp3 story02.mp3 story03.mp3
