Resumé

BEAMING is a telepresence research project aiming at providing a multimodal experience between two or more participants located at different locations. One of the BEAMING applications allows a distant teacher to give a xylophone playing lecture to the students. Therefore, rendering of the xylophone played at the student's location is required at the teacher’s site. This paper presents a comparison of different recording techniques for a spatial xylophone sound rendering, focusing on the horizontal width of the xylophone auditory image.

The directivity pattern of the xylophone was measured and spatial properties of the sound field created by a xylophone as a distributed sound source were analyzed. Xylophone recordings were performed using different microphone configurations: one and two-channel recording setups are implemented.

One-channel recording technique with binaural synthesis for spatial xylophone sound rendering is proposed. The recorded signal is processed in order to define multiple virtual sources which are spatially distributed for the auditory width representation of the virtual xylophone. The results of the analyzed recording and rendering techniques are compared in terms of the cross-correlation coefficient and subjectively by the listening test. The results show that the proposed method improves horizontal width perception of the xylophone auditory image.
