3D Audio Rendering
A technique which uses audio signal processing to spatialize sound anywhere in a 3D space.
Reverberation in VR
Simulated effect of sound reflecting from surfaces in a virtual environment to create a sense of space and depth.
Sound Localization
The process by which the listener is able to identify the location or origin of a detected sound in direction and distance.
Binaural Recording
A technique of recording audio with two microphones to create a stereo sound that mimics human ear placement.
Dynamic Range Compression
Used in VR to manage varying levels of audio signals to ensure no sound is too quiet or too loud for the listener.
HRTF (Head-Related Transfer Function)
HRTF is used to simulate how audio travels around the human head, including the shape of ears, to create a 3D audio effect.
Psychoacoustics in VR
Study of human perception of sound, important for designing spatial audio algorithms that exploit the brain's processing of auditory cues.
Doppler Effect in VR
Simulation of the change in frequency or pitch when a sound source moves relative to the listener, used for adding realism in VR audio.
Ambisonics
A full-sphere surround sound technique: it can capture sound from all directions, and playback over multiple speakers for a VR environment.
Occlusion and Obstruction
Audio techniques that simulate sounds being blocked or partially blocked by objects in the VR environment.
