Spatial Audio
An audio technology that simulates sound attenuation and directional change across three-dimensional space. In virtual social environments, it produces a natural social experience in which volume corresponds to the virtual distance between participants, closely replicating the acoustic behavior of in-person interaction.
Timeline (last 90 days)
Spatial audio, through techniques such as HRTF, gives sound a sense of direction and distance and can serve as an alternative channel to visual information, providing navigation and alerts for landmarks and teammate positions.
Apple's product history has precedents of features launching later, such as some Camera Continuity and spatial audio features.
Bringing spatial audio technology into practical use requires addressing issues such as the collection quality of consumer-grade devices, generalization ability across different acoustic environments, and the computational overhead of real-time inference.
Spatial audio processing generally does not fully satisfy LTI assumptions (for example, when it includes dynamic loudness control or head tracking), but measuring each virtual sound source position separately under static conditions can still extract valid HRTF filter coefficients and reverberation tails.
At the technical level, spatial audio relies on the Web Audio API's PannerNode, dynamically adjusting volume attenuation and panning by calculating avatar coordinates.
flat.social focuses on three core experiences: spatial audio, mini-games, and no download required.
