Everything about "3D sound" and its researches

What is a 3d sound

3D audio effects are a group of soundeffects that manipulate the sound produced by stereo speakers, surround-soundspeakers, speaker-arrays, or headphones. This frequently involves the virtual placement of sound sources anywhere in three-dimensional space, including behind, above or below the listener.

What is 3d audio processing

3-D audio (processing) is the spatial domain convolution of sound waves using Head-related transfer functions. It is the phenomenon of transforming sound waves (using head-related transfer function or HRTF filters and cross talk cancellation techniques) to mimic natural sounds waves, which emanate from a point in a 3-D space. It allows trickery of the brain using the ears and auditory nerves, pretending to place different sounds in different 3-D locations upon hearing the sounds, even though the sounds may just be produced from just 2 speakers (dissimilar to surround sound).

Revolutionary approach brings 3D sound into the living room

Computer vision and sound experts have demonstrated ‘Media Device Orchestration’ – an innovative home audio concept which enables users to enjoy immersive audio experiences by using all available devices in a typical living room.Computer vision and sound experts at the University of Surrey have demonstrated 'Media Device Orchestration' -- an innovative home audio concept which enables users to enjoy immersive audio experiences by using all available devices in a typical living room.The Media Device Orchestration (MDO) concept has been developed at Surrey in collaboration with the Universities of Salford and Southampton, and BBC Research & Development. It is being presented at the Audio Mostly conference in London on 24 August 2017.

Using the MDO concept, researchers have demonstrated that a 3D or 'spatial audio' experience can be achieved by employing everyday home devices in the living room such as a laptop, smartphone or wireless mini-speaker. The technology works by isolating different 'objects' within audio content (such as a particular voice), and connecting them to separate speakers available around the room.

The concept could enable consumers to enjoy films, games, programmes and music in a far more immersive, multi-layered and exciting way.

While it is possible to create 3D listening experiences using current spatial audio technology, this requires a complex set-up involving a multitude of speakers located at exact points in relation to the listener. Because of these limitations, the technology cannot easily be replicated in a domestic situation and is generally limited to specialist environments such as cinemas and theme park experiences.
