A management server includes a memory, and at least one processor configured to control an audio client system, by execution of instructions stored in the memory. The at least one processor is configured to acquire a first transfer function measured for a portion of or for all of the first signal path in the audio client system. The at least one processor is also configured to generate a virtual second signal path for a portion of or for all of the first signal path in the audio client system, and calculate a second transfer function for a portion of or for all of the generated virtual second signal path. The at least one processor is also configured to determine a condition of the audio client system, based on a result of a comparison between the first transfer function and the second transfer function.

Example systems, apparatus, and methods receive audio information including a plurality of frames from a source device, wherein each frame of the plurality of frames includes one or more audio samples and a time stamp indicating when to play the one or more audio samples of the respective frame. In an example, the time stamp is updated for each of the plurality of frames using a time differential value determined between clock information received from the source device and clock information associated with the device. The updated time stamp is stored for each of the plurality of frames, and the audio information is output based on the plurality of frames and associated updated time stamps. A number of samples per frame to be output is adjusted based on a comparison between the updated time stamp for the frame and a predicted time value for play back of the frame.

Examples disclosed herein provide the ability to identify the location of an individual within a room by using a combination of microphone arrays and voice pattern matching. In one example, a computing device may extract a voice detected by microphones of a microphone array located in a room, perform voice pattern matching to identify an individual associated with the extracted voice, and determine a location of the individual in the room based on an intensity of the voice detected individually by the microphones of the microphone array.

A suspension system is provided with a frame to mount to a side surface of a speaker cabinet with a plurality of apertures formed therethrough. The suspension system is also provided with a lever arm with a proximal end and a distal end that are both adapted to connect to an upper support. The lever arm also has an intermediate portion that is pivotally connected to the frame about a pivot axis with a plurality of arcuate slots formed through. Each arcuate slot is formed with an end stop that corresponds to a splay angle of the speaker cabinet relative to the upper support, and each slot aligns with one of the apertures to receive a pin. Whereby suspending the speaker cabinet from the upper support pivots the lever arm in a first direction until the pin engages the end stop.

An audio system includes a base station, an interface that enables transmission of audio content from a handheld media device to the base station via a cable, and one or more remote speakers configured to receive the audio content from the base station. The base station includes a housing, a speaker integrated within the housing to produce an audible signal from the audio content provided by the handheld media device, and a transceiver integrated within the housing for wirelessly transmitting the audio content to the one or more remote speakers. The one or more remote speakers are configured to wirelessly relay the audio content, thereby to supply the audio content beyond the transmission range of the transceiver.

An audio apparatus includes a housing, a piezoelectric vibration unit provided to the housing and having a piezoelectric element, and a communication unit for receiving an audio signal. When a received audio signal is applied to the piezoelectric element while a load of the audio apparatus is applied to the piezoelectric vibration unit, the piezoelectric element is deformed causing deformation of the piezoelectric vibration unit, whereby a contact surface in contact with the audio apparatus vibrates and generate a sound.

A bidirectional channel control system, method, device, and non-transitory computer-readable storage medium based on Digital Enhanced Cordless Telecommunications is provided. The system comprises a transmitter, at least one receiver, an audio channel, and a text message control channel. The transmitter is configured to send an audio data stream to the at least one receiver through the audio channel. The transmitter is configured to send a control command to the one receiver through the text message control channel in a one-to-one single-point text message mode, and to receive a feedback result from the one receiver in response to the control command. Alternatively, the transmitter is configured to send a control command to each of the at least one receiver based on DECT protocol through the text message control channel in at least one of a one-to-many broadcast messaging mode and a one-to-one single-point messaging mode, and to receive a feedback result from each of the at least one receiver in response to the control command in the one-to-one single-point messaging mode.

An example method of operation may include identifying, in a particular room environment, a number of speakers and one or more microphones on a network controlled by a controller and amplifier, providing test signals to play sequentially from each amplifier channel of the amplifier and the speakers, monitoring the test signals from the one or more microphones simultaneously to detect operational speakers and amplifier channels, providing additional test signals to the speakers to determine tuning parameters, detecting the additional test signals at the one or more microphones controlled by the controller, and automatically establishing a background noise level and noise spectrum of the room environment based on the detected additional test signals.
