Field facts

Path: imp.audio.minduration
Object: Audio
Type: integer
Default: 0 recommended
Requirement: Optional
Added: OpenRTB 2.4
Spec section: 3.2.8

How it is used

With Audio.maxduration it forms a duration range. Use the range when the break can absorb any length inside it, and Audio.rqddurs when only specific lengths fit.

Example

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

{
  "id": "req-1",
  "imp": [
    {
      "audio": {
        "minduration": 15
      }
    }
  ]
}

Common mistakes

Sending it together with Audio.rqddurs, which the validator reports as openrtb.fields.mutually_exclusive.
Sending milliseconds instead of seconds.
