The description relates to rendering directional sound. One implementation includes receiving directional impulse responses corresponding to a scene. The directional impulse responses can correspond to multiple sound source locations and a listener location in the scene. The implementation can also include encoding the directional impulse responses to obtain encoded departure direction parameters for individual sound source locations. The implementation can also include outputting the encoded departure direction parameters, the encoded departure direction parameters providing sound departure directions from the individual sound source locations for rendering of sound.

Bidirectional propagation of sound

A mobile device implemented method provides audio from a virtual audio source in an augmented reality view of a scene. The method includes operations of sending scene identification data to a server storing precomputed acoustic parameters for multiple scenes, receiving precomputed acoustic parameters corresponding to the scene, aligning the view to register the audio to the augmented reality view of the scene, and rendering and playing the audio using the obtained acoustic parameters.
