Efficient and effective use of low-cost 3D audio systems
MetadataShow full item record
Commercial, off-the-shelf (COTS) 3D sound cards offer a readily available low-cost option to consumers, researchers, and developers of 3D auditory displays. However, drawbacks of current 3D sound cards include computing platform support limitations, Application Programming Interface (API) complexity, vendor instabilities, and the lack of individualized Head-Related Transfer Functions (HRTFs). To address these issues, we have developed a client/server system utilizing COTS 3D sound cards and have investigated a method of visualfeedback training for 3D sound localization.
