AudioObject Schema for Webflow Websites

AudioObject schema describes an audio file or recording. It applies to podcast episodes (individual audio files), music samples, audiobook excerpts, sound effects, and any embedded audio content. AudioObject is a subtype of MediaObject.

Google does not maintain dedicated structured data documentation for AudioObject, but the type is referenced within other schemas (e.g., as associatedMedia in PodcastEpisode).
