Binaural 3D audio is played from a two-channel audio file (WAV, MP3, …) or CD-audio and gives the listener an immersive sound experience. Binaural 3D Audio simulates the human spatial hearing via every kind of stereo headphones (no special models are required). When listening to stereo audio with headphones, the perception of all sources of sounds is located inside of the head between the left and right ear. With binaural 3D Audio the sound appears outside of the head and can be anywhere within a full 360° three-dimensional sphere. Voices, instruments and sounds can be positioned around the listener – in front of, behind, right, left and even below or above and everywhere in between – and can be placed in a virtual acoustic environment such as rooms and halls, studio and outdoor ambiences.
Binaural 3D audio sounds amazing in audiobook, radio play, shortfilm or documentary video productions and can not only improve the spatial, acoustic presentation of dialogues, atmos, sounds, foley and music, but also creates a much more emotional listening experience. Audiovisual presentations, sound installations, and interactive AR / VR projects use multi-channel immersive audio formats, such as Ambisonics, where multiple mono or stereo sound sources are played through extensive speaker and soundbar systems (more than Surround Sound). In games, 360° videos and Virtual Reality applications, sounds for interaction can be integrated in this way.
