mp3chapters

Command line utility for adding chapter marks to mp3 files.

Many podcast and audiobook apps on Android and iOS support chapter markers in mp3 files

This uses the eyeD3 lib to read and write the chapters details

requirements

Python 3

installation

pip3 install mp3chapters

usage

The chapter markers format should be in either:

- Timecode: hours:minutes:seconds.milliseconds + space + chapter title
- Milliseconds: milliseconds (whole) + space + chapter title
- Audacity: seconds (floating point) + tab + seconds (no used) + tab + chapter title

Assuming you have a file named episode_42.mp3, mp3chaps looks for a chapter marks file called episode_42.chapters.txt in the same directory:

00:00:00.000 Introduction
00:02:00.000 Chapter Title
00:42:24.123 Chapter Title

00000000 Introduction
00060000 Chapter Title
