A display apparatus that includes circuitry that displays a user interface screen including device information that identifies a plurality of output device groups and a plurality of input device groups to control connection between one of the output device groups and one of the input device groups; and receives an input that designates a combination of said one of the output device groups and said one of the input device groups, the user interface screen includes a matrix comprising a plurality of cells in a row direction and a column direction, the input designates the combination by designating one of grouped cells corresponding to the combination of said one of the output device groups and said one of the input device groups in the matrix, and the grouped cells are grouped such that the input designates the combination as a group.

A first example playback device includes one or more processors and a non-transitory computer-readable medium storing instructions that, when executed by the one or more processors, cause the first playback device to perform functions. The functions include generating a mixed audio signal comprising one or more components of a first audio stream and one or more components of a second audio stream; and playing the mixed audio signal, where the one or more components of the second audio stream of the mixed audio signal played by the first playback device are played in synchrony with a second playback device configured to play the second audio stream. An example non-transitory computer-readable medium and an example method, both related to the first example playback device, are also disclosed herein.

Systems and methods for a signal mixing device are provided. An example method includes generating a mixing request during a live performance based on sensed mouth movement when sensed audio from the mouth is less than a threshold. In such an example method, the sensed mouth movement may be generated from a sensor mounted separately from an audio sensor of a microphone, and may be displayed at a mixing console during the live performance.

A system may include a mobile device configured to transmit at least one system variable control signal indicative of an audio processing command, and a translation controller distinct and separate from the mobile device. The translation controller may be configured to receive the system variable control signal, and transmit a mixer message in a protocol specific to an audio mixing console based on the system variable control signal, the mixer message including at least one audio processing command.

Sound device receives a first sound signal from a first sound processor, generates a second sound signal based on the first sound signal, and transmits the second sound signal to a second sound processor. The second sound processor performs signal processing to the second sound signal to generate a third sound signal. The sound device receives the third sound signal from the second sound processor, checks a state of the second sound processor based on a signal received from the second sound processor, transmits a fourth sound signal based on the third sound signal to the first sound processor when determining that the state of the second sound processor is normal, and generates a fifth sound signal based on the first sound signal or the second sound signal to transmit it to the first sound processor when determining that the state of the second sound processor is abnormal.

Image data relating to real-world objects or persons is collected from a scene while collecting audio data relating to the real-world objects or persons from the same scene. The audio data is used to derive sound objects corresponding to the real-world objects or persons. The image data is used to derive video objects corresponding to the real-world objects or persons. Based on the sound objects and the video objects, candidate salient objects are generated. A salient object is selected from among the candidate salient objects. Perceptual enhancement operations are performed on the selected salient object.

In live music performances it is desirable for a mixing console operator to be able to hear the result of all the processing of a single input signal provided by the various processing steps without the other input signals being present. This is achievable by providing a console (10) which processes an input signal independently of other input signals to produce an operator output signal (210), wherein the processing is arranged to be identical to that applied in combination to the same signal as it is processed, in combination with other signals, for the creation of an output mix (180).
