Synthesis of 3D virtual auditory space via a spatial feature extraction and regularization model
J. Chen, B.D. Van Veen, Kurt E. Hecox · 2002
A functional representation for head-related transfer functions (HRTFs) is desirable as it overcomes many of the limitations associated with use of measured HRTFs. It provides a continuous representation of auditory space, such that the synthesis of HRTF at any given spatial location can be performed by functional evaluation of the model. Such a model that establishes a mathematical representation of the external ear transformation characteristics based on spatial feature extraction and regularization is proposed.>
