Zusammenfassung:System-wide clock synchronization and latency reduction of audio signals in a wireless multi¬ channel audio system (WMAS). The apparatus includes: abase station and a wireless audio device. The base station includes: a master clock source; a framer operative to generate base station frames containing audio data and related audio clock timing derived from said master clock source; and a transmitter operative to transmit the frames over the WMAS. The wireless audio device includes: a receiver operative to receive frames from the base station over the WMAS; a frame synchronization circuit operative to generate audio data and a related timing signal from the received frames; and a clock generator circuit operative to input a local clock signal generated by said frame synchronization circuit to generate therefrom multiple clocks derived from the timing signal to synchronize the wireless audio device to base station frames and to enable thereby communications according to a previously determined schedule with the base station.
