Overview

This tool adds chapters to an audio file using a label or chapters file. Upload your audio and a text file with timestamps and titles to embed navigable chapter markers directly into the audio metadata.

When preparing audio for distribution on platforms that support chapter metadata, such as podcast apps or audiobook stores.

How it works

1Upload your audio file in a supported format like MP3 or WAV.
2Upload a label file with chapter definitions: each line includes start time (seconds), end time (seconds), and an optional title, separated by tabs or spaces.
3The tool processes the files and embeds the chapters into the audio file's metadata.
4Download the modified audio file with chapters ready for use in compatible players.

Use cases

Enhancing podcast episodes with chapter markers to help listeners jump to specific segments like interviews or news.
Creating chapterized audiobooks for distribution on digital platforms, improving user experience with easy navigation.
Adding structure to educational audio content, such as lectures or tutorials, by segmenting them into labeled chapters.

Examples

1. Add Chapters to a Podcast Episode

Podcast Producer

Background

You produce a weekly podcast and want to add chapters to make long episodes more navigable for listeners.

Problem

Listeners often skip through episodes to find specific parts, leading to a poor experience.

How to use

Upload the podcast audio file and a text file with chapter timestamps and titles, such as '0 120 Introduction' and '120 300 Interview'.

Outcome

The podcast episode now has embedded chapters, allowing listeners to easily jump to sections in their audio player.

2. Segment an Audiobook into Chapters

Audiobook Narrator

Background

You've recorded an audiobook and need to divide it into chapters based on the book's structure for publishing.

Problem

Manually inserting chapters in audio editing software is time-consuming and error-prone.

How to use

Provide the complete audiobook audio file and a label file listing chapter start and end times with titles, like '0 300 Chapter 1: The Beginning'.

Outcome

A chapterized audiobook is generated, ready for upload to platforms like Audible or Apple Books with proper navigation.
