AB  - In videoconference systems formed by microphone and loudspeaker arrays, the sound field reproduced in the receiving room must be as similar as possible to the sampled field by the microphone array (according to the wave field synthesis). Different measurements of objective and subjective quality can be made. A measurement method has been developed based on spatial localization in the horizontal plane. Two different situations have been compared: first, a real source placed at different azimuth angles in front of the listener; second, the virtual source created by the loudspeaker array. Interpolated HRTFs have been calculated according to several methods and in order to determine the azimuth angle the cross correlation function (IACC) and the interaural time difference (ITD) have been evaluated.
