Spatial audio processing is the set of signal-processing techniques that position sound sources in three-dimensional space for a listener, using cues such as direction, distance and room acoustics.

- Spatial audio processing renders sound so that a listener perceives sources as coming from specific locations in three dimensions. It applies head-related transfer functions, interaural level and time differences and reverberation models to recreate directional and distance cues, typically for binaural playback over headphones.
- In telepresence and virtual environments, spatial audio helps participants localise speakers and separate overlapping voices, improving intelligibility in group settings. Accurate reproduction depends on head tracking and, for best results, personalised transfer functions.
