Digital Audio Workstations

Depending on your existing setup, a new audio interface that supports at least 10 or more physical outputs might be necessary – the number of outputs required being defined by your chosen speaker configuration. Similarly, you may require a monitor controller or room-eq solution that supports 10 or more speakers. There are several solutions available from many different manufacturers at various price-points.
 
You may also want to review your plugins to see if there are updated versions or alternatives that have additional features that will assist with your Dolby Atmos mixes. While plugins designed for Dolby Atmos are quite new there are any increasing number, such as reverbs, compressors, and delays that have been redesigned to add spatial support.

For a DAW to be suitable for mixing Dolby Atmos Music it needs to either natively integrate, or be able to connect to, a Dolby Atmos Renderer. In addition, the DAW needs to support three-dimensional object panning. While some DAWs now feature native immersive panners, which can be used for mixing music, the Dolby Atmos Music Panner is commonly used as this supports additional DAWs and also includes music-focused features such as a tempo-based object positioning sequencer. While it may be possible to get other DAWs to work, the ones listed above have been tested by Dolby either due to their integration of native rendering or as part of our development of the Dolby Atmos Renderer and/or Dolby Atmos Music Panner.

Headphone processing is enabled in the Renderer Preferences (Mac) or Settings (Windows). This is also where you choose if the headphone output will be a stereo output or binaural. The audio output device outputs used for the headphone are set in the Room Setup Window Routing page. There is also a headphone only mode enabled from the Preferences or Settings that lets you use another set of outputs and turns off the speaker outputs when engaged.
