Abstract: An audio system including a first microphone-equipped playback device and a second microphone-equipped playback device. The audio system is configured to synchronize playing of audio to a listener position by receiving by the first microphone-equipped playback device an audio stream, and playing the audio stream on a speaker of the first microphone-equipped playback device, in accordance with a playback delay ?t. The playback delay ?t is in accordance with a first calibration sound originating at the listening position, a second calibration sound originating at the second microphone-equipped playback device, and a third calibration sound originating at the first microphone-equipped playback device.

Abstract: An audio input configured to input an audio stream and a noise reduction module configured for processing the audio stream for emphasizing speech content. A monophonic detector is configured to determine whether the audio stream is either monophonic or not monophonic. A decision module is configured to receive an input from the monophonic detector and to output a decision to bypass the noise-reduction when the audio stream is not monophonic.

Abstract: A computerized microphone-equipped audio playback device comprising a speaker and microphone and being configured to receive digital audio; and play the digital audio on a speaker, in accordance with a playback delay that is derivative of, at least: an arrival time of a first calibration sound at the processor and an arrival time of the first calibration sound at a second microphone-equipped audio playback device, wherein the first calibration sound originated at the listener position; a generation time of a second calibration sound at the second microphone-equipped audio playback device, and an arrival time of the second calibration sound at the processor; and a generation time of a third calibration sound at the processor, and an arrival time of the third calibration sound at the second microphone-equipped audio playback device; thereby synchronizing arrival of sound of the two playback devices at the listener position.

Abstract: First and second computer systems and respective first and second microphones thereof receive respective portions of a same audio input signal. Audio buffers received respectively from the first and second computer system include data encoded from respective microphone inputs of the first and the second computer systems. The received audio buffers are synchronized and corrected for gain differences between the received audio buffers to produce corrected audio buffers. The corrected audio buffers are mixed into an output buffer. The synchronization reduces echo when the output buffer is played at a remote peer computer system.
