Spatial property exchange (SPE)

The Spatial Property Exchange is an abstract protocol for sending and receiving spatial properties across applications.

SPE enables spatially-aware audio processing. Audio effects using SPE can create more immersive output as they are aware of where their input signals are located within the scene. SPE also allows output signals to be given spatial properties.

SPE-enabled applications can be designed so that the user only needs to think of audio sources as one abstract idea instead of a pairing of audio data and spatial data.
