Abstract:
Embodiments of sound leveling in multi-channel sound capture system are disclosed. According to a method, a processor converts at least two input sound channels captured via a microphone array into at least two intermediate sound channels. The intermediate sound channels are respectively associated with predetermined directions from the microphone array. The closer to the direction a sound source is, the more the sound source is enhanced in the intermediate sound channel associated with the direction. The processor levels the intermediate sound channels separately. Further, the processor converts the intermediate sound channels subjected to leveling to a predetermined output channel format. Because sound leveling of the intermediate sound channels can be achieved independently of each other, at least some of the deficiencies of the conventional gain regulation can be overcome or mitigated.
Abstract:
In some embodiments, apparatuses, systems, and methods are provided herein for performing sound analysis in a shopping facility. A system for performing sound analysis comprises: an array of sound sensors distributed throughout a shopping facility and configured to receive at least sounds resulting from people in the shopping facility, an audio database including information associated with one or more audio indicia, and a control circuit communicatively coupled to the array of sound sensors and configured to receive, from a plurality of sensors of the array of sound sensors, audio data, wherein the audio data includes audio from throughout the shopping facility, determine, based at least in part on the audio data and the information associated with the one or more audio indicia included in the audio database, an action be taken, and transmit, to a terminal, an indication of the action to be taken.
Abstract:
A method is provided for encoding multiple microphone signals into a composite source-separable audio (SSA) signal, conducive for transmission over a voice network. The embodiments enable the processing of source separation of the target voice signal from its ambient sound to be performed at any point in the voice communication network, including the internet cloud. A multiplicity of processing is possible over the SSA signal, based on the intended voice application. The level of processing is adapted with the availability of the processing power at the chosen processing node in the network in one embodiment. An apparatus for separating out the target source voice from its ambient sound is also provided. The apparatus includes a directed source separation (DSS) unit, which processes the two virtual microphone signals in the SSA representation, to generate a new SSA signal including the enhanced target voice and the enhanced ambient noise.
Abstract:
[Object] The present disclosure proposes a control device, control method, and computer program capable of executing control such that information can be displayed more appropriately and efficiently according to an environment in which information is displayed or a situation of displayed information. [Solution] Provided is a control device including: an acquisition unit configured to acquire state information obtained by detecting a state of a projection surface; and a generation unit configured to generate control information for controlling an illumination unit that outputs illumination without involvement in display of image information based on the state information.
