SpatialAudioKit is a Swift package to facilitate authoring of Spatial Audio apps on Apple platforms. It lets you add head-tracked binaural playback of various Spatial Audio files to your iOS or macOS app, with a few lines of Swift code. It supports opus encoded files (in a ogg .opus container) for multi-channel file playback, alongside formats natively supported by AVFoundation and can be extended for other formats.
SpatialAudioKit is also a collection of tools for producers working with Spatial Audio. The SAKPlugins can be used in a Digital Audio Workstation to listen to Spatial Audio mixes binaurally. They can receive OSC messages from SAKHeadtracker to rotate the sound scene.
SpatialAudioKit is a project by Oli Larkin, with a lot of help from Kartik Venogopal.
