    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： 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.

    摘要： Embodiments described herein involve configuring a playback device based on the detection of a barrier in proximity to the playback device. One embodiment may involve causing the playback device to play an audio content, where a first speaker of the playback device is arranged to output in a first direction and configured to play a component of the audio content; receiving proximity data that includes an indication of a barrier that is proximate to the playback device; detecting that the barrier is within a threshold proximity to the first speaker of the playback device; based on the detecting, causing the first speaker to be deactivated; and causing a second speaker of the playback device to play at least the component of the audio content, where the second speaker arranged to output in a second direction that is different from the first direction.

    摘要： There is provided a method of operating a device to generate a target sound that is audible to a user of the device, the method comprising measuring background noise in an environment in which the device is located; using a perceptual loudness model to predict an audibility of the target sound to the user of the device based on the measured background noise; using the output of the perceptual loudness model to determine a gain value that is to be applied to a source signal used to generate the target sound in order to provide at least a desired level of audibility of the target sound to the user; applying the determined gain value to the source signal to produce a modified source signal; and generating the target sound using the modified source signal.
