3D Sound reconstruction is the application of reconstruction techniques to 3D sound localization technology to create robust 3D audio effects.

Motivation and Applications

When reconstructing recorded 3D audio and visualizing sound fields, sound localization and reconstructing the reverberation and sound pressure are critical to produce robust and natural-sounding audio. There are various techniques to process sound so that the spatial cues can be reproduced when reconstructing sound. This technology sees a demand in entertainment as audiences look for the ambience of a live performance reproduced through their speakers. Reconstructing a 3D sound field also becomes critical in military applications where visualizing pressure in a 3D sound field can help determine location of sound sources. The techniques used for sound field reconstruction are similar to those used to reconstruct sounds to detect solid objects, but applied to a gaseous field to detect changes in pressure and sound intensity.^[1] Emulating the mechanisms of binaural hearing can improve recognition accuracy and signal separation in DSP algorithms, especially in noisy environments.
