Changeover Between Audio Systems Patents (Class 369/2)
  • Patent number: 10299039
    Abstract: An audio system includes one or more loudspeaker cabinets, each having loudspeakers. Sensing logic determines an acoustic environment of the loudspeaker cabinets. The sensing logic may include an echo canceller. A low frequency filter corrects an audio program based on the acoustic environment of the loudspeaker cabinets. The system outputs an omnidirectional sound pattern, which may be low frequency sound, to determine the acoustic environment. The system may produce a directional pattern superimposed on an omnidirectional pattern, if the acoustic environment is in free space. The system may aim ambient content toward a wall and direct content away from the wall, if the acoustic environment is not in free space. The sensing logic automatically determines the acoustic environment upon initial power up and when position changes of loudspeaker cabinets are detected. Accelerometers may detect position changes of the loudspeaker cabinets.

  • Patent number: 10255026
    Abstract: An apparatus and a system are provided in which a user can easily check that an appropriate audio file is assigned to an immediate output switch. The system includes a PC connected to a communication line, and an audio interface apparatus connected to the PC and having an immediate output switch for outputting, to the PC and in response to a user operation, a reproduction start instruction signal of an audio file which is assigned in advance. The PC judges whether or not assignment is normal when the audio file is assigned by a user operation, and supplies a judgment result to the audio interface apparatus. The audio interface apparatus receives the judgment result, and notifies, to the user and prior to a user operation, the judgment result in association with the immediate output switch.

    Abstract: In transmitting stream data to a recording unit through a network, there is a method to detect that a synchronous recording has been designated from an input unit to transmit mute data to a recording unit through the network for a first predetermined time period during which the streaming data is held in a data holding unit for the first predetermined time value. In the case where it is determined that the data that the data holding unit holds is held for a second predetermined time value, the inputted stream data is transmitted to the recording unit through the network. The recording unit is permitted to record, in the state where sound is not interrupted, and it is permitted to execute data recording, in which operating time of mechanical parts is required so that the operating state of the recording unit shifts to the recording state, and/or responses relating to the control of the recording unit are taken into consideration.

  • Patent number: 7266390
    Abstract: A network interface cassette for coupling signals between a wireless network and a tape head in a cassette tape player. The network interface cassette includes an enclosure that is conformed to the cassette tape form factor. It contains a transceiver that converts base band signals for radio frequency communications within the wireless network. It also contains a network controller that is coupled to communicate the base band signals with the transceiver. The network controller converts digital audio signals to and from the base band signals. There is an audio processor that converts the digital audio signals to analog audio signals. A coupling means converts the analog audio signals to magnetic audio signals. The coupling means is aligned to couple the magnetic audio signals to the tape head. A power supply with batteries and a generator driven from the cassette player capstan are provided. A wireless user interface adapter is provided to couple microphone and audio signals to the apparatus.

  • Patent number: 7212469
    Abstract: There is provided a mixing recorder which enables the user to readily produce music using overdubbing and/or other recording techniques while suppressing degradation of sound quality to the minimum and enables the user to easily find out his/her desired mixing result from a large number of mixing results obtained in the process of mixing. An audio signal is input, and a source file is read out from a memory card and an audio signal is reproduced based on the source file. The input audio signal and the reproduced audio signal are mixed into a mixed signal, which is then stored as a new source file in the memory card. The source file stored in advance in the memory card is backed up before the new source file is stored in the memory card, and in the back-up, the source file is automatically backed up by generating a file given a new name associated with a name of a source file to be backed up and having the same contents as the contents of the source file.

  • Patent number: 7203142
    Abstract: A DVD audio signal reproducer reproduces a DVD to generate a DVD reproduced audio signal. A reproduced signal determiner determines whether the DVD reproduced audio signal is a 5.1-channel digital surround audio signal or a 2-channel digital audio signal, and generates a determination signal. If the determination signal indicates that the DVD reproduced audio signal is a 5.1-channel digital surround audio signal, a digital surround effector converts the DVD reproduced audio signal to a 2-channel digital surround audio signal.

  • Patent number: 7170828
    Abstract: This invention comprises a two part audio system in which all of the processing power is allocated to a small, lightweight satellite part that is the face unit. Mass storage, amplification, and wired power for recharging the face unit is provided by the other part, the base. The base runs either from a 120 volts AC source or 12 volts DC. The face unit contains a small amount of flash memory making it capable of carrying music normally stored on two or more compact discs (CDS).

  • Patent number: 7016266
    Abstract: A sharing device is composed of a distributor and multiple output units. The distributor has multiple input ports to connect different audio sources, such as VCD/DVD players, and has multiple output ports to correspondingly connect to the multiple output units. Each output unit is further connected with a sound output device, e.g. speakers, to broadcast audio signals. When the multiple output units are distributed at different locations, a user in any place is able to select a desired audio source by controlling the output unit and listen to music provided by the selected audio source.

  • Patent number: 6969794
    Abstract: The data of the same musical pieces are stored in the same order in each of a plurality of music playback apparatuses. When one music playback apparatus is instructed to finish musical-piece playback, it generates musical-piece playback information indicating the playback order of the musical piece being played at that time, and sends the musical-piece playback information to a mobile telephone. The mobile telephone receives the musical-piece playback information and stores it in its internal memory. When the mobile telephone is moved to a position around another of the music playback apparatuses, the mobile telephone sends the musical-piece playback information to the other music playback apparatus. When the other music playback apparatus is instructed to start musical-piece playback, it selects the musical piece to be played back next, according to the musical-piece playback information sent from the mobile telephone, reads the data of the selected musical piece, and starts playing back the musical piece.
