摘要:
An audio system having an improved sound field by generating a center audio channel from left and right stereo channels. The center channel is preferably generated by summing the left and right channels, and then filtering the resulting output. The center channel signal is also combined with the left and right channel signals to remove a portion of the monophonic information from the left and right channels thereby maintaining a constant level of monophonic information in the sound field.

Embodiments of the disclosure provide methods, apparatus, and articles allowing two nodes to communicate in a slot-based direct sequencing spreading communication system. Both a preamble sequence and a payload data spreading PN sequence are generated from the Time of Day and a given user code. Generated sequences are synchronized between two communicating nodes to allow slot-based DSSS communication to take place. Generated sequences also change dynamically from slot to slot to provide waveform security.
