    摘要： An acoustic capture device includes an acoustic transducer, an acoustic detector, an analog-to-digital converter, and a processing element. The acoustic transducer captures an acoustic wave to generate an analog signal. The acoustic detector detects, according to the analog signal, a specific event to generate a trigger signal. The analog-to-digital converter converts the analog signal to generate a digital signal. The processing element receives the trigger signal to execute a control process. The control process includes: analyzing the digital signal to determine ambient information; determining a first set of parameters of the acoustic detector according to the ambient information; performing a control information protocol to adjust the acoustic detector according to the first set of parameters; and performing, according to the ambient information, an enhancement processing on the digital signal to generate an enhanced digital signal.

    摘要： A computing system automates the configuration and management of a live sound system that includes a processor and memory for building in a GUI of a display a representation of the live sound system for a venue. The system loads a venue template that includes loudspeaker arrays and related properties including a setup configuration of the loudspeaker arrays and tuning data for constituent loudspeakers that are operable to provide an audio coverage pattern for the venue. The system overlays on top of the representation of the loudspeaker arrays a wiring circuit representation indicating interconnections of the loudspeakers that define bandpass inputs for each array. The system generates a plurality of amplifiers in the representation to drive the arrays, and associates amplifier channels of the amplifiers with the bandpass inputs. The amplifier channels include representations of output channels of DSPs coupled with respective amplifier channels. The system loads tuning data into respective representation of the DSP and/or amplifiers based on configurations of the associated loudspeakers to complete virtual configuration. The representations of the devices and connections may be matched with physical devices of the live sound system and the tuning data sent down to the physical DSPs and/or amplifiers for their configuration.

    摘要： The various embodiments relate generally to systems, devices, apparatuses, and methods for providing audio streams to multiple listeners, and more specifically, to a system, a device, and a method for providing independent listener-specific audio streams to multiple listeners using a common audio source, such as a set of loudspeakers, and, optionally, a shared audio stream. In some embodiments, a method includes identifying a first audio stream for reception at a first region to be canceled at a second region, and generating a cancellation signal that is projected in another audio stream destined for the second region. The cancellation signal and the first audio steam are combined at the second region. Further, a compensation signal to reduce the cancellation signal at the first region can be generated.

    摘要： Embodiments described herein involve configuring a playback device based on the detection of a barrier remaining in proximity to the playback device until a gating condition is satisfied. In an example embodiment, a playback device receives sensor data, and determines, based on the received sensor data, that a barrier has remained within a threshold proximity to the playback device for at least a threshold duration of time. In response to determining that the barrier has remained within the threshold proximity to the playback device for at least the threshold duration time, a playback configuration is applied to the playback device. This playback device may adjusts audio output of the playback device at one or more frequency ranges. After applying the playback configuration, the playback device play backs audio content according to the playback configuration.

    摘要： A noise-suppression device includes an input buffer, a spatial filter, a delay buffer, and a controller. The input buffer stores sound data. The spatial filter generates processed data by using an internal adaptive control according to a control signal. The delay buffer stores the processed data. The controller operates in either one of a training stage, a flushing stage, or a normal stage and generates the control signal. When the controller operates in the training stage, the spatial filter receives the sound data from the input buffer to generate the processed data which is continuously processed by the spatial filter and then stored in the delay buffer over and over again until the internal adaptive control is converged.
