TAG: Surround
Surround sound is a technique for enriching the sound reproduction quality of an audio source with additional audio channels from speakers that surround the listener (surround channels), providing sound from a 360° radius in the horizontal plane (2D) as opposed to “screen channels” (centre, [front] left, and [front] right) originating only from the listener’s forward arc.
Surround sound is characterized by a listener location or sweet spot where the audio effects work best, and presents a fixed or forward perspective of the sound field to the listener at this location. The technique enhances the perception of sound spatialization by exploiting sound localization; a listener’s ability to identify the location or origin of a detected sound in direction and distance. Typically this is achieved by using multiple discrete audio channels routed to an array of loudspeakers.[1]
There are various surround sound based formats and techniques, varying in reproduction and recording methods along with the number and positioning of additional channels.

3DVMS
The 3D VMS, acronym of 3D Virtual Microphone System, is a sound recording system that thanks to a microphone array and a processing system patented by RAI with the University of Parma allows the synthesis of virtual microphones (Virtual Microphones) whose orientation and directivity can be controlled and modified in real time.
