Introducing Microsoft Project Acoustics 

Microsoft Project Acoustics is a next-gen, physics-based acoustical modeling and wave propagation plugin that analyzes game geometry and material properties to build realistic wave simulations of sound diffraction, occlusion, and reverberation for dynamic sounds.Recently, Epic and Microsoft collaborated on a direct plugin integration for UE5—now free via the Unreal Marketplace. If you want a walkthrough, check out this talk. You’ll see how it integrates with Lyra and hear about its high-level capabilities, including the utilization of a new UE Audio source-data interface.
