3D Positional Audio effects emerged in the 1990s in PC and ame consoles. 3D audio techniques have also been incorporated in music and video-game style music video arts. True representation of the elevation level for 3D loudspeaker reproduction become possible by the Ambisonics and wave field synthesis (WFS) principle.
Neumann KU 100 microphone used to record binaural sound. Binaural recording is a method of recording sound that uses two microphones, arranged with the intent to create a 3D stereo sound sensation for the listener of actually being in the room with the performers or instruments.
Most famous sound effects were recorded in Modena at Umbi's Studios by sound engineer Maurizio Maggi. Holophonic is patented and registered by Umberto Maggi (Italy). Zuccarelli states that the human auditory system is a sound emitter, producing a reference sound that combines with incoming sound to form an interference pattern inside the ear.
3D sound system with Reverberation Reconstruction flowchart. The reverberation reconstruction involves measuring the sound by a four-point microphone to measure its real delivery delays in different locations. Each microphone measures an impulse response from a time-stretched pulse signal for various time frames with various sound sources.
SRS. Sound Retrieval System (SRS) is a patented psychoacoustic 3D audio processing technology originally invented by Arnold Klayman in the early 1980s. [citation needed] The SRS technology applies head-related transfer functions (HRTFs) to create an immersive 3D soundfield using only two speakers, widening the "sweet spot", creating a more spacious sense of ambience, and producing strong ...
An application of 3D sound synthesis is the sense of presence in a virtual environment, by producing more realistic environments and sensations in games, teleconferencing systems, and tele-ensemble systems. 3D sound can also be used to help those with sensory impairments, such as the visually impaired, and act as a substitute for other sensory feedback.

Sensaura's 3D positional audio technology was designed to build upon the industry standard Microsoft DirectSound3D API, which allowed games to have high quality audio in three dimensions. HRTF 3D audio positioning with low CPU usage. Virtual Ear features common HRTF profiles (libraries) that can be selected by the end-user.
