Cognitive loudspeaker system
Abstract:
A cognitive loudspeaker system including a control station that communicates wirelessly and bi-directionally with a plurality of sound production stations. The control station and the sound production stations are initially synchronized to a conductor clock. Configuration information is then transmitted from the sound production stations to the control station. In response, the control station generates playback executables, which are transmitted to the sound production stations. The control station also transmits digital audio information to the sound production stations. Within each sound production station, the previously received playback executable is used to control the decoding and processing of the received digital audio information. Each sound production station generates digital audio output samples, which are converted to analog output signals. These analog output signals are amplified and are used to drive loudspeakers.
