Dolby DP590 Broadcast Audio Object Authoring
The Dolby DP590 Broadcast Audio Object Authoring tool is a key element of Dolby’s industry leading object-
based audio authoring toolkit that assists broadcasters, live audio mixers and engineers in the adoption and
deployment of immersive audio for live events.
Dolby’s object-based audio (OBA) authoring toolkit for broadcast applications consists of the DP590 Broadcast Audio
Object Authoring tool (DP590), the DP591 Audio Encoder (DP591) and the DP580 Professional Reference Decoder (DP580).
This toolkit provides the ability to do immersive audio authoring, encoding, and monitoring.
The DP590 provides a user friendly interface to give the audio engineer easy access to set up and deliver a new immersive
audio experience as channel-based audio (e.g. 5.1.2, 5.1.4). It does this by ingesting audio groups from the mixing console
and providing a simple way to create object audio presentations, including mapping sounds to locations in 3D space, and
developing associated metadata. It also provides an easy way to monitor the changes to the immersive audio content
that has been created, including emulating different speaker configurations.
Dolby DP590 Broadcast Audio Object Authoring—March 1st, 2017
The DP590 wraps around an audio mixing console as show in the diagram shown below. It enables audio engineers to define
and monitor the various combinations of the audio elements that they wish to create. Each defined combination is referred
to as a Presentation, and downstream decoders can be set to decode and render each presentation—for example,
“5.1 English”—whenever this is required. The metadata used within the presentation is fully defined in the DP590 and
is therefore under the control of the audio engineer. Presentations can be appropriately named for the production and
may refer to languages, targeted delivery paths, or enhanced experiences as desired by the producers.
