摘要： The sound reproduction of a multichannel sound reproduction system with a plurality of speakers which is connected to the output of an FM stereo receiver is controlled by a control signal derived from the reception quality. Preferably, the control signal from the FM stereo receiver for controlling the stereo and mono components is also employed to control the multichannel sound reproduction system. For example, stereo, pseudo-stereo or mono reproduction are provided in the multichannel sound reproduction system in response to the stereo component within the output signal.

摘要： A bit-stream converter capable of converting a first synchronous compressed bit-stream of data at a first sampling rate to second synchronous compressed bit-stream frame of data at a second sampling rate is disclosed. The bit-stream converter architecture may include a payload length detector and a zero stuffing unit in signal communication with the payload length detector. The zero stuffing unit is capable of zero stuffing section responsive to the payload length detector detecting the payload length.

摘要： Sound processing systems have been developed that create a surround effect without quality degradation experienced by known sound processing systems in non-optimum listening environments. The sound processing systems may include matrix decoding systems that manipulate input signals prior to converting them into a number of output signals so that the output signals are a function of a greater number of input signals. These sound processing systems may also or alternately include a bass management system that from the input signals preserves the low frequency components of the input signals in separate channels. Both the matrix decoding systems and bass management systems may also produce additional signals. Further, the matrix decoding and bass management systems may be implemented separately or jointly in vehicular sound systems.
