Speaker Or Channel Switching Patents (Class 381/85)
  • Patent number: 10779105
    Abstract: A system and method to encode and decode multiple audio signals to provide independent control of the audio signals is provided. A host device may encode the audio signals to enable a complete separation of the constituent audio signals when the mixed stream is decoded on a playback device. The gains of the audio signals may be independently controlled before they are mixed to increase the intelligibility of one audio signal relative to another audio signal at the playback device. The ability to separate the constituent audio signals from the mixed signals at the playback device allows the processing operations performed on the constituent audio signals and the associated path latencies to be independently chosen. In addition, in applications where the mixed stream is transmitted from a single host device to multiple playback devices, the constituent audio signals may be selectively masked on a playback device to increase user privacy.

That is, a computing device may provide audio signals with a particular apparent source location within a user's soundstage. Initially, a first audio signal may be spatially processed so as to be perceivable in a first soundstage zone. In response to determining a high priority notification, the apparent source location of the first audio signal may be moved to a second soundstage zone and an audio signal associated with the notification may be spatially processed so as to be perceivable in the first soundstage zone. In response to determining user speech, the apparent source location of the first audio signal may be moved to a different soundstage zone.

  • Patent number: 8401680
    Abstract: When any one of a plurality of amplifiers has been selected in response to amplifier selecting operation, an amplifier Detail View of the selected amplifier is displayed, where corresponding parameters are displayed via elements of the amplifier Detail View. When any one of a plurality of groups has been selected in response to group selecting operation, a group Detail View of the selected group is displayed, where maximum and minimum values detected from among values of a parameter of individual amplifiers of the selected group are displayed via a band-shaped element of a corresponding fader element. In another example, where a hierarchical group is selected in a tree display section on a control screen, respective state information, including parameter values or states of parameters, of a plurality of amplifiers belonging to the selected hierarchical group is displayed in a state information section.

  • Patent number: 8401681
    Abstract: Systems and methods of placeshifting media playback between two or more devices are provided. For example, a method for placeshifting media may include sending a first message from a media-receiving electronic device to a media-playing electronic device playing a media file and receiving a response identifying the media file and a point at which the media file was being played when the first message was received. The media-receiving electronic device may play a copy of the media file at the point where the media-playing electronic device left off.

  • Patent number: 8295500
    Abstract: Sound can be listened to only in a listening area by maximizing a sound energy difference between a listening area and a non-listening area while maximizing sound radiation efficiency of each sound source. Accordingly, realistic sound can be provided to listeners without causing auditory disturbance to third parties, and maximal sound effects can be obtained with only minimal control.

    Abstract: There is provided a multichannel audio amplification apparatus including a speaker detection circuit for detecting whether or not a speaker is connected to an arbitrary speaker terminal of speaker terminal groups TA and TB, and an operating circuit and a display circuit connected to a control circuit. Even in a case where one of two speaker groups of A and B types connected to the multichannel audio amplification apparatus cannot be connected with a surround speaker for reproducing only a surround sound, a listener is prevented, by indication, from carrying out on the operating circuit an erroneous operation or setting which otherwise might be liable to occur both in a case where the B-type speaker group including no surround speaker is connected to the multichannel audio amplification apparatus and in a case where the B-type speaker group is not connected thereto.
