Definition of 3D audio effect
Three-dimensional audio effects (3D audio effects) are a group of sound effects that manipulate the sound produced by stereo speakers, surround-sound speakers, speaker-arrays, or headphones. This frequently involves the virtual placement of sound sources anywhere in three-dimensional space, including behind, above or below the listener.
3D audio (processing) is the spatial domain convolution of sound waves using head-related transfer functions. It is the phenomenon of transforming sound waves (using head-related transfer function or HRTF filters and cross talk cancellation techniques) to mimic natural sounds waves, which emanate from a point in a 3D space. It allows trickery of the brain using the ears and auditory nerves, pretending to place different sounds in different 3D locations upon hearing the sounds, even though the sounds may just be produced from only two speakers (dissimilar to surround sound).
