Abstract: The present invention relates to a communication system for communication of a plurality of stereo audio signals between a plurality of communication devices, 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, an audio interface 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, an input communication interface configured to receive a first stereo audio signal and a second stereo audio signal of the plurality of stereo audio signals transmitted by the second communication device and the third communication device, respectively. The first stereo audio signal may comprise a second voice signal of a second user of the second communication device, and the second voice signal may include a second spatial information, and wherein the second stereo audio signal 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. Furthermore, the communication device may comprise an output communication interface configured to transmit a third stereo audio signal 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.

Abstract: A communication system for communicating a plurality of audio signals between a plurality of control devices, wherein the plurality of control devices comprises at least a subsequent control device and at least a preceding control device. Each control device of the plurality of control devices comprises; an audio port configured to receive a local voice signal of a user of the control device, wherein the local voice signal may be extended into a first local voice signal and a second local voice signal. Additionally, the control device comprises a primary audio input port configured to receive a first audio signal of the plurality of audio signals transmitted by the subsequent control device, wherein the first audio signal comprises a second voice signal of a second user of the subsequent control device, and a secondary audio input port configured to receive a second audio signal of the plurality of audio signals transmitted by the preceding control device, wherein the second audio signal comprises a third voice signal of a third user of the preceding control device. Furthermore, the control device comprises a primary audio output port configured to transmit a third audio signal of the plurality of audio signals comprising the first local voice signal and the second audio signal to the subsequent control device, and a secondary audio output port configured to transmit a fourth audio signal of the plurality of audio signals comprising the second local voice signal and the first audio signal to the preceding control device. Additionally, the control device comprises an internal audio mixer configured to mix the first audio signal and the second audio signal into an internal audio signal, and wherein the primary audio input port and the primary audio output port of the control device may be coupled to the secondary audio output port and the secondary audio input port of the subsequent control device, respectively, and wherein the secondary audio input port and the secondary audio output port of the control device may be coupled to the primary audio output port and the primary audio input port of the preceding control device, respectively, and wherein the control device comprises a first volume controller configured to control the sound level of the first local voice signal and the second local voice signal and a second volume controller configured to control the sound level of the internal audio signal and transmit the internal audio signal to the audio port.
