A COMMUNICATION SYSTEM FOR COMMUNICATING AUDIO SIGNALS BETWEEN A PLURALITY OF COMMUNICATION DEVICES IN A VIRTUAL SOUND ENVIRONMENT

摘要

The present invention relates to a communication system (1) for communication of a plurality of stereo audio signals between a plurality of communication devices (10), wherein the plurality of communication devices comprises a first communication device, a second communication device and at least a third communication device. Each communication device of the plurality of communication devices may comprise a signal processing unit (24), an audio interface (4) configured to receive a local voice signal of a user of the communication device, a binaural rendering unit configured to render the local voice signal into a stereo local voice signal based on a first spatial information (α1), an input communication interface (3) configured to receive a first stereo audio signal (12A) and a second stereo audio signal (12B) of the plurality of stereo audio signals transmitted by the second communication device (10B) and the third communication device (10C), respectively. The first stereo audio signal (12A) may comprise a second voice signal of a second user of the second communication device (10B), and the second voice signal may include a second spatial information (α2), and wherein the second stereo audio signal (12B) may comprise a third voice signal of a third user of the third communication device, and where the third voice signal may include a third spatial information (α3). Furthermore, the communication device may comprise an output communication interface (2) configured to transmit a third stereo audio signal (12C) of the plurality of stereo audio signals comprising the local voice signal provided with the first spatial information to the second communication device and the third communication device. The first stereo audio signal and the second stereo audio signal may be transmitted to the audio interface, and the user of the communication device experiences a virtual sound environment, wherein the second voice signal and the third voice signal is positioned in the virtual sound environment based on the second spatial information and the third spatial information, respectively.
