How to Create Chapters in a Single Audio File


I’m new to Audacity and this forum, so I apologize if this question was already asked. I have a long audio file (documentary) and would like to insert “chapters” so that when I playback the file I can fast forward or rewind by chapter.

I’ve been doing a lot of reading about “Labels” but that seems to split the file up into separate “sub-files”.

Is there a way to achieve what I’m looking to do?

Thanks in advance for your help.

:frowning: Most digital audio formats don’t support chapters. You my have to find an audio book format and an appropriate audio book player application.

From what I understand, AAC supports chapters, but you’d have to figure-out how to add the chapter information (maybe iTunes?) and your player also has to support them (maybe iTunes/iPod?).

The “shiny disc” formats (CD/DVD/Blu-Ray) all support chapters or track markers.

Most audio formats supports “tags” so you can add a track number to a file. I’ve copied a couple of audio books from CD to MP3 with a separate files for every chapter (and sometimes for a sub-chapters). And, any audio player can play the files in track-number order.

Producing chapters in a sound file is Frequently Requested. Another way to do it is a single-picture video file.


“Chapter and Verse” is a free Windows program that does exactly what you need:

It will also convert most audio files to AAC, which is the only audio format I know that supports chapters natively. Every player that supports AAC should be able to see chapters. MP4 supports it too, but that is a video container. I have a feeling some audio players might not support chapters, but I’ve never tried it.

Ogg Vorbis, FLAC and Opus formats can use an extension to support chapters:

However, a lot of players didn’t support this last time I looked.

An overview of possible solutions, from the Auphonic blog:

I’ve never tried Auphonic, which is a webservice, free for up to two hours/month. Of course, Auphonic can add chapters too and it does a lot of other stuff too. Some of it sounds like snake oil, like “clipping removal”, fi.
