The head-related transfer functions (HRTFs) are essential ?lters used in three-dimensional audio playback devices for personal use. They describe the transmission of sound from a point in space to the eardrums of a listener. Obtaining near-distance HRTFs is important to increase the realism when presenting sounds in the peripersonal space. However, most of the publicly available datasets provide HRTFs for sound sources beyond one meter. We introduce a collection of generic and individual HRTFs for circular and spherical distributions of point sources at distances ranging from 10 cm to 100 cm, spaced 1 cm. The HRTF datasets were calculated using the boundary element method. A sample of the dataset is publicly available in the spatially oriented format for acoustics (SOFA).
