feed 2 means FM/AM Broadcast

When to send it

Send 2 when the ad runs in the online stream of a radio station that also broadcasts over the air. The content is live and scheduled, so ad breaks follow the station's clock, and ads are usually stitched into the stream on the server.

Buyers see broadcast simulcast as radio audiences reached digitally, often bought alongside traditional radio. Breaks have fixed lengths, so Audio.rqddurs and Audio.startdelay matter. It is confused with 5 (Web Radio), which is also live but has no over-the-air signal, and with 4 (Catch-up Radio), which is a recording.

Example

{
  "imp": [
    {
      "audio": {
        "feed": 2
      }
    }
  ]
}
