Authoring and Mixing Object-Based Audio Content

Nuendo supports the creation, the import, and the export of Audio Definition Model (ADM) files with object-based audio content in Broadcast Wave Format (BWF). You can either set up ADM projects from scratch or import ADM BWF files, such as complete Dolby Atmos or MPEG-H Audio premixes with objects and beds, into existing projects, preserving the ADM file structure and pan automation.

You can create ADM files in Broadcast Wave Format (BWF) with object audio and channel-based beds for playback through external renderer applications or devices.

Generally, we recommend that you start a new ADM project by creating a group track with a surround channel configuration as a bed. First of all, route the tracks that you want to use as source tracks to this group track. This ensures that these tracks use VST MultiPanner as the channel panner. This signal routing is automatically modified when you define beds and objects in the ADM Authoring window.

All audio objects in your object structure – beds as well as objects – need a source track that sends an audio signal to it. Any audio track, group track, or instrument track in your project can act as a source track for audio objects. If a track is selected as a source track, its VST MultiPanner channel panner is switched to object mode, and its audio signal is automatically re-routed from the bed to the renderer.

As a renderer, you can either use an internal ADM renderer plug-in, the Renderer for Dolby Atmos or the Renderer for MPEG-H, or connect your system to an external ADM renderer, such as the Dolby Atmos Renderer application or an external OSC renderer.
