The 3D simulation is the most advanced group of 3D audio effects.
Using head-related transfer functions and reverberation, the changes of sound
on its way from the source (including reflections from walls and floors) to the
listener's ear can be simulated. These effects include localization of sound
sources behind, above and below the listener.
Some 3D technologies also convert binaural recordings to stereo
recordings. MorrowSoundTrue3D converts binaural, stereo, 5.1 and other formats
to 8.1 single and multiple zone 3D sound experiences in realtime.
3D Positional Audio effects emerged in the 1990s in PC and Game
Consoles. As a medium, interactive games would benefit perhaps more than any
other. However, although some technologies do seem to work better than others,
3D sound in games is still quite unconvincing, especially over
speakers.[citation needed]
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.

Some amusement parks have created attractions based around the
principles of 3-D audio. One example is Sounds Dangerous! at Disney's Hollywood
Studios at the Walt Disney World Resort in Florida. Guests wear special earphones
as they watch a short film starring comedian Drew Carey. At a point in the
film, the screen goes dark while a 3-D audio sound-track immerses the guests in
the ongoing story. To ensure that the effect are heard properly, the earphone
covers are color-coded to indicate how they should be worn. This is not a
generated effect but a binaural recording.
