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.
3-D 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 3-D space. It allows trickery of the brain using the ears and auditory nerves, pretending to place different sounds in different 3-D locations upon hearing the sounds, even though the sounds may just be produced from just 2 speakers (dissimilar to surround sound). [Note that, transfer function is a function that depict the relationship between an input and the output of a system. It’s a fraction representation with the denominator not equal to 1, if there’s feedback in the system. If the transfer function e.g. Z-transform is localized to the unit circle (or bi-unit circle or tri-unit circle for 2-D and 3-D cases respectively), it then becomes the Multidimensional Fourier Transform (see Multidimensional transform) or the frequency response of the system.
