Head Related Transfer Functions (HRTFs) are signal processing models that represent the modifications undergone by the acoustic signal as it interacts with the listener's body. HRTFs can be used to generate binaural sound as they contain all the information about the sound source's location. This paper describes a database of head-related transfer functions based on ear/head measurements measured at the FIU DSP Lab. HRTF data from 15 subjects at 12 different azimuths and 6 different elevations are included. This database also includes 3-D images of the subject's pinnae (outer ears). Anthropometric measurements of the various parts of the pinna are included.
