​
Overview

The backlog audio dataset provides access to audio files from past events. Each event includes two URLs to allow for both streaming and downloading.

​
How it works

Each audio record in the API response includes URLs that point directly to audio files hosted on our CDN, so you can stream or download them without any additional authentication. Audio is served in both MPEG format for downloading and M3U8 format for HLS streaming.
Audio records are linked to events through eventId. Use the expand parameter to include event metadata directly in the response.

​
Chapters

Audio files can be divided into structured segments using chapters. Use the chapters endpoint to retrieve hierarchical sections with titles and timestamps for a given audio record.
