Abstract
A wireless personal-area network (PAN) communication system includes a first device configured to simultaneously transmit a digitized stereo audio signal to and receive a digitized voice signal from a second device over the wireless PAN. The system also includes the second device, which is configured to simultaneously receive the digitized stereo audio signal from the first device and transmit the digitized voice signal to the first device over the PAN. The wireless PAN can be a Bluetooth® network. Low-latency audio codecs may be included in the first and second devices to reduce the latency of the voice and stereo audio signals transferred between the devices.
