Current research in videoconferencing is focussed on 3D-Sound reproduction over a wide listening area. This paper compares two methods: Holophony and Ambisonic. First, it will be shown that Ambisonic actually corresponds to a particular case of holophonic reconstruction, then the specificities of the two approaches will be analysed in terms of complexity and size of listening area. As a result, a third method, which shall combine the advantages of both Holophony and Ambisonic, will be suggested.
