The HTML mark up produced by this template includes an hAudio microformat, which makes the recording's details parsable by computers, either acting automatically to catalogue articles across Wikipedia, or via a browser tool operated by a person, to (for example) add the subject to a playlist or database. For more information about the use of microformats on Wikipedia, please see the microformat project.

Date-of-publication ("published") information will only be included in the microformat if {{Start date}} (or {{Start date and age}} where appropriate) is used in a parent template or infobox (but do not use these if the date is before 1583 CE).

For the length or duration of a recording, say 3 minutes 45 seconds, use {{Duration}} thus: {{Duration|m=3|s=45}}, which renders as 3:45. An optional h parameter can be used for hours.

Please do not remove instances of these sub-templates.

hAudio uses HTML classes including:

  • haudio
  • fn
  • album
  • description
  • category
  • contributor
  • duration
  • h
  • item
  • min
  • photo
  • position
  • price
  • published
  • s

Please do not rename or remove these classes; nor collapse nested elements which use them.
