Two methods of 3D-sound reproduction for videoconferencing are compared: Holophony and Ambisonic. Previous studies have shown that they are based on equivalent reconstruction process. First comparisons between their sound pick-up approach conclude that the Ambisonic spatial encoding is more efficient, though unfeasible. The present paper completes this analysis by examining the sound reproduction step. Finally a hybrid method is proposed.
