VAudio is a format that allows audio ads to be delivered in environments where video inventory is required.
Instead of sending a pure audio file, the system converts it into a video-compatible format.
How It Works
When a VAudio campaign responds:
- The system takes an audio file (MP3)
<MediaFiles>
<MediaFile delivery="progressive" type="audio/mp3" bitrate="371">
<![CDATA[ https://cdn-us.live.demand.com/vast/tide.mp3 ]]>
</MediaFile>
</MediaFiles>- Converts it into an MP4 video file
<MediaFiles>
<MediaFile delivery="progressive" width="0" height="0" bitrate="128" type="video/mp4">
<![CDATA[ https://cdn-us.live.indicue.com/ott-creatives/icc1_vaudio_1770623873535018338_video.mp4 ]]>
</MediaFile>
</MediaFiles>- The resulting video contains:
- audio track (original ad)
- black screen (no visual content)
From the player’s perspective, this is a video ad, but effectively it is audio-only playback
