'''3D audio effects''' are a group of [[sound effect]]s 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.<ref>{{Cite web|url=https://sites.google.com/site/kart3dsoundtechnology/|title=PERCEPTION OF SOUND SOURCE DIRECTION|last=|first=|date=|website=|archive-url=|archive-date=|access-date=}}نث▼

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]]).

3D audio techniques have also been incorporated in music and video-game style music video arts. The Audioscape research project, provides musicians with a real-time 3D audiovisual content authoring and rendering environment, suitable for live performance applications.

Other investigations included the Jago 3D Sound project which is looking at using [[Ambisonics]] combined with STEM music containers created and released by Native Instruments in 2015 for 3D nightclub sets.
