Abstract: A multimedia system includes at least a first pair of satellite loudspeakers for radiating left and right channel signals, the satellite loudspeakers having a first lower cutoff frequency. The loudspeaker system also includes a separate subwoofer having a first upper cutoff frequency. The first lower cutoff frequency is higher in frequency than the first upper cutoff frequency. The loudspeaker system also includes a center loudspeaker array. The center loudspeaker array radiates center channel signals, and also directionally radiates left and right channel signals in the frequency range between the first lower cutoff frequency and the first upper cutoff frequency. The multi-channel loudspeaker system may also incorporate additional satellite loudspeakers for reproduction of surround channel signals.

Abstract: Processes and devices for equalizing an audio system that is adapted to use a loudspeaker to transduce test audio signals into test sounds. The processes and devices can involve the use of infrared signals to convey information in one or both directions between the audio system and a portable computer device that captures test sounds, calculates audio parameters that can be used in the equalization process, and transmits these audio parameters back to the audio system for its use in equalizing audio signals that are played by the audio system.

Abstract: The technology described in this document can be embodied in a method of reproducing audio related to a teleconference between a second location and a remote first location. The method includes receiving data representing audio captured by a microphone array disposed at the remote first location. The data includes directional information representing the direction of a sound source relative to the remote microphone array. The method also includes obtaining, based on the directional information, information representative of head-related transfer functions (HRTFs) corresponding to the direction of the sound source relative to the remote microphone array, and generating, using one or more processing devices, an output signal for an acoustic transducer located at the second location. The output signal is generated by processing the received data using the information representative of the one or more HRTFs, and is configured to cause the acoustic transducer to generate an audible acoustic signal.
