Abstract: A computing device transmits one or messages that including a synchronizing protocol to the loudspeakers. The loudspeakers transmit one or more responses to the computing device in response to the messages. Through the transmission and receipt of messages and responses, the computing device synchronizes all of the speakers to a universal time.

Abstract: Improved approaches to flexibly implementing graphic equalizers on media players are disclosed. These approaches provide dynamic order reduction of a multi-band graphic equalizer so that equalizer effects can be timely performed with only limited computational resources. In one embodiment, a media player receives a media item and associated equalizer settings for a multi-band graphic equalizer. The media player can then automatically (i.e., without user action) approximate the multi-band graphic equalizer with the equalizer settings for the media item using a fewer number of filters. Fewer filters means order reduction, and thus reduction in computational requirements. After the multi-band graphic equalizer is approximated, the media player can present the media item to its user in accordance with the reduced complexity, approximated equalizer.

Abstract: Systems and methods for directing pickup of media content by way of user input are disclosed. These systems and methods enable desired media content to be more effectively acquired. The user input can be locally provided or remotely provided. The systems and methods for directing pickup of media content are particularly suitable for video conferencing systems. The media content being directed is, for example, video or audio.

Abstract: A technique for enhancing audio signals generated from compressed digital audio files is described. The technique uses a Bass Maximizer module, a Harmonic Exciter module and a Quasi Stereo module. The Bass Exciter module enhances the intensity, depth and punch of the bass audio content by creating harmonic sequences from low frequency components contained in the original input signal. The Harmonic Exciter module adds to the treble audio content of the original input signal by generating harmonic series from the high frequency components contained in the input signal. The Quasi Stereo Module creates a stereo image of the enhanced input signal by adding and subtracting delayed and filtered versions of the enhanced input signal with itself to create left and right channeled stereo-like outputs. The technique provides a useful tool to regenerate from an audio signal more pleasant and joyful sounds.
