Trim and Downmix Editor

The Trim and Downmix Editor dialog allows you to specify the trim and downmix settings for playing back your Dolby Atmos project.

The settings made in this editor are part of the static metadata of your Dolby Atmos project and stored in the ADM file when exporting. A renderer uses these settings for playback or encoding.

To open this dialog, select Trim and Downmix Editor from the Settings pop-up menu in the ADM Authoring for Dolby Atmos window.

Trim and Balance Settings

In this section, you can make individual trim and balance settings for 5.1/2.0, 5.1.2, and 7.1 downmixes.

Trim (Surround/Height): Allows you to lower the level for surround and height channels.
Balance (Overhead/Listener Plane): Allows you to set the balance for overhead and listener plane.

Downmix Control Settings
