| Résumé |
This paper describes a database of high spatial resolution head-related transfer functions (HRTF) measurements for 54 subjects (42 males, 12 females) and 3 dummy heads. The head-related impulse responses (HRIR) have been measured in IRCAM’s anechoic chamber using the exponentional sweep sine technique and a sampling rate of 96 kHz. Microphones were positionned at the entrance of the blocked ear canal. The spatial sampling scheme is based on a Gaussian grid and includes 1680 directions with full azimuth range (0° to 360°), and elevation ranging from -51° to +86°. The angular step size is approximately 6 degrees in both dimensions. The subjects head position and orientation are tracked with an infrared optical motion capture system. The HRIR are publicly available in the standardized SOFA file format. |
