        String Comment "The head-related impulse responses (HRIR) have been measured in IRCAM's anechoic chamber\012using the exponentional sweep sine technique and a sampling rate of 96 kHz. Microphones were\012positionned at the entrance of the blocked ear canal. The spatial sampling scheme is\012based on a Gaussian grid and includes 1680 directions with full azimuth range (0 deg to 360 deg),\012and elevation ranging from -51 deg to +86 deg. The angular step size is approximately 6 degrees in both\012dimensions. The subjects head position and orientation are tracked with an infrared optical motion capture system.";
