AVFoundation is Apple's comprehensive framework for time-based audiovisual media on Apple platforms, enabling playback, capture, and editing with deep hardware and software integration [developer.apple.com](https://developer.apple.com/av-foundation/). It differentiates through seamless support for HTTP Live Streaming (HLS), real-time camera and microphone processing, and low-level audio sample manipulation [developer.apple.com](https://developer.apple.com/library/archive/documentation/AudioVideo/Conceptual/AVFoundationPG/Articles/00_Introduction.html). The framework provides a unified API across iOS, iPadOS, macOS, tvOS, visionOS, and watchOS, allowing developers to build rich media experiences from simple playback to complex video compositing [developer.apple.com](https://developer.apple.com/av-foundation/).
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.
Core Media is a framework for working with media in Apple platforms.
