Parallel Audiobook Binder

Parallel Audiobook Binder is, as the name implies, a fully parallelized audiobook binder aka MP3 to M4B converter. It supports setting chapters from either MP3 files or from a CUE sheet.

Features:

• Parallelized Conversion: Parallelized audio trancoding from MP3 to M4B/AAC
• Chapter Support: Set chapters from CUE sheets or chapterized MP3 files.
• Sorting Mechanism: Sort input files by ID3v2 track number if available, or alphabetically if not.
• Metadata Management: Extracts and embeds metadata such as author, title, and release date.

Installation

• Clone the repo
• Install requirements:

  pip3 install -r requirments.txt

• Ensure that FFmpeg is installed, download from here as neccesary: https://ffmpeg.org/download.html

  ffmpeg -version

Running the program

Run the TUI using the following command:

python3 binder.py

Or run binder.py with command line arguments like so:

python3 binder.py [-i INPUT] [-o OUTPUT] [-b BITRATE] -c {files,cue,none}

Arguments:

Argument	Description
-h, --help	Show list of arguments
-i INPUT, --input INPUT	Path to the input files (optional, default is current directory)
-o OUTPUT, --output OUTPUT	Path to the output file (optional, default is same as INPUT)
-b BITRATE, --bitrate BITRATE	Bitrate of the output m4b file in kb/s (optional, default is 128k, use "-1" to get the same bitrate as the input mp3 files)
-c {files,cue,none}, --chapters {files,cue,none}	Set the source for chapter data. Use "files" to use each mp3 file as a chapter, "cue" to get chapter data from a CUE sheet, "none" to not embed chapters (Required)
