How it is used

It is the main audio segmentation signal, because listener context and measurement differ sharply between feeds. OpenRTB 2.4 and 2.5 defined only the first three values. AdCOM has since added 4 through 7 and groups all of them into on-demand, live, and miscellaneous classes.

Allowed values

ValueMeaning
1Music Streaming Service: On-demand music streaming (AOD class); labeled Music Service in OpenRTB 2.4 and 2.5.
2FM/AM Broadcast: A radio station broadcast over the air and also streamed online (LIVE class).
3Podcast: Original, pre-recorded episodes published as a series (AOD class).
4Catch-up Radio: A recording of a radio show that first aired live (AOD class). Not in OpenRTB 2.5.
5Web Radio: A live station available only as an online stream, with no AM or FM broadcast (LIVE class). Not in OpenRTB 2.5.
6Video Game: Background audio inside a video game (MISC class). Not in OpenRTB 2.5.
7Text to Speech: Synthesized speech, such as audiobooks or a site plugin that reads articles aloud (MISC class). Not in OpenRTB 2.5.
500+Vendor-specific codes: Vendor-specific feed types (MISC class), agreed between partners in advance.

Example

Where the field sits in a payload, with everything else left out:

{
  "id": "req-1",
  "imp": [
    {
      "audio": {
        "feed": 3
      }
    }
  ]
}

Common mistakes

  • Classifying podcast inventory as 1 because the app also streams music. Classify by what is playing when the ad runs.
  • Sending 4 through 7 to a partner that validates against the 2.5 list, which ends at 3.
