PyPI GitHub PyPI - Python Version Python package CodeFactor Grade PyPI - Downloads


The steps accomplished by using this tool are as follows:

  • Easy batch inputs via -i folder1/ folder2/* file.mp3 etc.
  • Only user input required is one ASIN per book.
  • Converts mp3(s) into single m4b files
    • Matches existing bitrate and samplerate for target file.
    • Standardizes chapter names, like 'Chapter 1'.
  • Merges or edits m4a/m4b into single m4b file, without re-converting.
  • Moves input file/folder to done folder when processed.

Audible data features:

  • Title, author(s), narrator(s), series, release year, description
    • For generating folder structure
    • For seeding M4b metadata fields
  • Chapters (title and length) used for m4b/m4a inputs.

CLI usage

usage: m4b-merge [-h] -i INPUTS [INPUTS ...] [--log_level LOG_LEVEL]

m4b-merge cli

optional arguments:
  -h, --help            show this help message and exit
  -i INPUTS [INPUTS ...], --inputs INPUTS [INPUTS ...]
                        Input paths to process
  --log_level LOG_LEVEL
                        Set logging level
  • Check the user editable variables in, and see if there's anything you need to change.
  • On first run, you will be prompted to signin to Audible. This is a one-time process that will be saved to your system's relevant config folder, under m4b-merge.

Module usage

If you are a developer wanting to use this in a project, you can import the modules as so: from m4b_merge import audible_helper, config, helpers, m4b_helper

And then creating the objects you need (from audible_helper.BookData(asin) and m4b_helper.M4bMerge(input_data, metadata)) You can see more usage examples in the sister project, Bragi Books

The parser function in audible_helper.BookData returns some extra data not used in the CLI here. This is a list of all data returned:

  • Title
  • Short Summary
  • Long Summary
  • Authors
  • Narrators
  • Series
  • Release Date
  • Publisher
  • Language
  • Runtime in minutes
  • Format type (abridged, unabridged, other)
