The veracity of virtual audio is degraded by the use of non-individualized head-related transfer functions (HRTFs) due to the introduction of front-back, elevation confusions, and timbral coloration. Hence, an accurate reproduction of spatial sound demands the use of individualized HRTFs. Measuring distance-dependent individualized HRTFs can be extremely tedious, since it requires precise measurements at several distances in the proximal region (<1 m) for each individual. This paper proposes a technique to model distance-dependent individualized HRTFs in the horizontal plane using “frontal projection headphones playback” that does not require individualized measurements. The frontal projection headphones [Sunder, Tan, and Gan (2013). J. Aud...
