Firelight Technologies FMOD Studio currently supports Dolby Atmos for PC, Xbox Series X|S and mobile. FMOD can be integrated with both Unity 3D and Unreal Engine, which enables support of spatial audio that is then rendered to Dolby Atmos. FMOD supports a main mix bus of 7.1.4, which is then converted to Dolby Atmos by the Dolby Atmos Renderer. For mobile this is done in the Dolby Atmos plug-in in FMOD. Note: The FMOD surround panner handles panning on the X/Y axis, while the height slider to the left of the panner is used to control the amount of signal sent on the Z axis to the height speakers vs the ear level speakers.
For PC and XBox Series X|S, the audio designer should select "Surround 7.1.4" on the Master Track Speaker configuration as the output bus. The Output mode selection (Edit -> Preferences -> Output Device) should be set to "Windows Sonic" to route spatial audio to the Windows 10 Core OS layer where it is converted to Atmos by the integrated Dolby Atmos Renderer. To route audio to be spatialized for Atmos, the Output bus should be set to "Surround 7.1.4".
For Atmos Audio Objects, FMOD has an Object panner that interfaces with Object based output modes like Windows Sonic. On PC and XBox Series X/S the objects are passed through to the Windows 10 Core for conversion to Dolby Atmos objects. For passthrough audio such as music that the designer does not want spatialized, assign the output bus on the individual track to mono or stereo
For mobile, create a submix group bus and apply the Dolby Atmos renderer plug-in as an effect on the signal chain of the bus. The plugin handles converting the 7.1.4 main bus to the 5.1.2 rendering used on mobile phones. There are no separate objects on mobile; they are rendered as part of the bed channels. Contact games@dolby.com for the plug-in. Please refer to the documentation downloaded with the plug-ins for more detail on supported phones, installation and configuration.
