As a part of another project, I made a small plugin that allows connecting 360’ audio layers to Sequencer sequences. I just made the plugin available on github for free, in case that someone else happens to find it useful.
Plugin page on github: GitHub - hiili/Sequencer360Audio: [Unreal Engine plugin] Facebook 360 audio plugin (TBAudioEngine by Two Big Ears) and Sequencer integration
More specifically, the plugin uses the Facebook / Two Big Ears 360’ audio plugin (TBAudioEngine, see Spatial Workstation – Facebook 360 Video) to play .tbe 360’ audio files with fully automatic playback and synchronization with a given Level Sequence Actor. The plugin monitors the assigned reference sequence and automatically handles starting, pausing, stopping, seeking and playback rate changes. Playback rate changes due to global time dilation are also handled.
You probably do not need this if you just run sequences linearly from the beginning to the end, but in more nonlinear cases (for example, due to user interaction) this might save you some work!
