Soundscape(also: Auditory Soundscape, Audio Landscape)
An auditory environment where multiple spatialized sounds represent objects or landmarks in all directions around a listener, creating an acoustic representation of physical space. In accessibility applications, soundscapes use spatial audio technology to make virtual objects…
Spatialization(also: Spatialisation, Audio Spatialization, 3D Audio Spatialization)
The process of rendering a sound so that it appears to originate from a specific location in three-dimensional space around the listener. Spatialization typically combines head-related transfer functions (HRTFs) to model how ears filter sound by direction, binaural or ambisonic…
Spatialized Audio(also: 3D Audio, Spatial Sound, Immersive Audio)
Spatialized audio is a technology that creates the perception of sound coming from specific locations in three-dimensional space around the listener, using techniques such as head-related transfer functions (HRTFs) and binaural rendering. In accessibility, spatialized audio is…
Spatialized Sound(also: Spatial Audio, 3D Audio, Spatialized Audio)
Audio that is rendered with positional information so that it appears to originate from a specific location in three-dimensional space around the listener. Spatialized sound uses techniques like head-related transfer functions (HRTFs), interaural time differences, and interaural…
Stereo Panning(also: Audio Panning, Pan)
The technique of distributing a mono sound signal between the left and right channels of a stereo output to create the perception that the sound originates from a specific horizontal position in space. A fully left-panned sound plays only in the left ear, a centered sound plays…
