摘要
A conference system with transmitting and receiving sides. The transmitting side has a microphone array unit with microphone capsules, and a processing unit. The processing unit is configured to receive output signals of the microphone capsules and to execute audio beamforming based on the received output signals for acquiring sound coming from an audio source in a first direction. The processing unit has a direction-recognition unit that computes from the output signals of said microphone capsules a score for each of multiple search grid spatial positions and uses a search grid spatial position having a higher score to identify said first direction. The receiving side has an audio reproduction system that reproduces an audio signal detected by the microphone array with directional information of the first direction. The detected audio signal and the directional information regarding the first direction are transmitted from the transmitting side to the receiving side.
