MP3 Chapter Splitter

Overview

This Python script automates the process of extracting individual chapters from an MP3 file. It utilizes ffprobe to analyze the MP3 file and determine the start and end times for each chapter, and then uses ffmpeg to extract and save each chapter as separate MP3 files.

Requirements

• Python 3.x
• FFmpeg (and ffprobe) installed on your system

Usage

1. Clone this repository or download the script mp3_chapter_splitter.py to your local machine.

2. Open the script in a text editor and configure the following parameters:

   • input_file: The path to the input MP3 file from which you want to extract chapters.
   • output_directory: The directory where the extracted chapters will be saved.

3. Run the script using the following command:

   python mp3_chapter_splitter.py

4. The script will use ffprobe to analyze the input MP3 file and determine the start and end times for each chapter. It will then use ffmpeg to extract and save each chapter as separate MP3 files in the specified output directory.

5. Once the script completes, you will find the individual chapters in the output directory.

Example

Suppose you have an MP3 file named input.mp3 with chapters, and you want to extract them into the output_chapters/ directory. You would configure the script as follows:

input_file = "input.mp3"
output_directory = "output_chapters/"

Then, you would run the script, and it would automatically extract all chapters and save them in the output_chapters/ directory.

Note

This script does not re-encode the audio during extraction, preserving the original audio quality.
