Abstract:
An audio system comprising:a signal source for outputting audio signals; a first sound source for receiving said audio signals supplied by said signal source to reproduce and output sound; compensation means for generating compensation signals for suppressing standing waves by signal-processing said audio signals; and a second sound source for receiving said compensation signals supplied by said compensation means to reproduce and output sound for suppressing standing waves; wherein said compensation means comprises: correlator means for determining a cross-correlation function between a transfer function from said first sound source to a listening location and a transfer function from said second sound source to said listening location; filter means having frequency characteristics based on said cross-correlation function generated by said correlator means; and signal inverting means; said filter means filtering said audio signals, and said signal inverting means inverting signals generated through said filtering, whereby compensation signals to be supplied to the second sound source are generated.
