Spatial audio refers to techniques and technologies that simulate the perception of sound coming from specific directions or locations in a three-dimensional space. In platforms like Arcane Mirage, Unreal Engine's spatial audio capabilities enhance immersion, realism, and interactivity by spatializing sound sources based on the listener's position and orientation within a virtual environment. Spatial audio techniques include binaural audio rendering, 3D sound propagation, and environmental effects, enabling developers to create realistic auditory experiences, enhance gameplay immersion, and improve spatial awareness in virtual reality (VR) simulations, games, and interactive media. By integrating spatialaudio, developers can immerse users in dynamic soundscapes, simulate realistic acoustic environments, and enhance the overall audio-visual experience in Unreal Engine applications.
