Apple has introduced Apple Immersive Video (AIV) and Apple Spatial Audio Format (ASAF), new media formats for visionOS, designed for adaptive, high-quality stereoscopic experiences on Apple Vision Pro. These technologies merge advanced capture, metadata-driven precision, and tailored audio into a unified workflow, impacting both production and delivery. AIV focuses on high-fidelity visual acuity and a wide field of view, while ASAF unifies object, channel, and HOA audio for spatial and perceptual demands.
