  • Patent number: 10855949
    Abstract: In some aspects, control circuitry receives and stores a user-specified time duration to associate with a skip-forward command. When the user later issues a skip-forward command to advance playback of a media asset to a desired location, the control circuitry retrieves the stored time duration, and determines an expected overshoot value associated with the skip-forward command. The control circuitry then compensates for the expected overshoot by calculating a new location in the media asset based on both the retrieved time duration and expected overshoot value. Upon advancing to the new location, the media asset is played back in a fast-forward mode, e.g., at a speed higher than normal speed.

  • Patent number: 10134382
    Abstract: A vehicle sound effect generation apparatus includes a running state detecting unit that detects a running state of a vehicle, an adjustment wave sound selector that selects one or more adjustment wave sounds having a half-order frequency component or an integer-order frequency component, a sound effect generation unit that synthesizes a fundamental wave sound having a fundamental frequency component with the one or more adjustment wave sounds selected by the adjustment wave sound selector, and an inhibition condition determining unit that can determine a condition that correspondence between an amount of an operation performed by a vehicle occupant and a behavior of the vehicle is inhibited. When the inhibition condition determining unit determines the condition that the correspondence between the amount of the operation and the behavior of the vehicle is inhibited, the adjustment wave sound selector reduces the output characteristics of the adjustment wave sounds selected.

  • Patent number: 10089980
    Abstract: A sound reproduction method is provided. The method includes acquiring ambient sound information that includes voice spoken to a speech dialog system and indicates sound around a speaking person who has spoken the voice. The method also includes separating the ambient sound information into first sound information including the spoken voice and second sound information including sound other than the spoken voice. The method further includes comparing the sound level of the first sound information with the sound level of the second sound information, and reproducing an audio response to the spoken voice, by selecting one of a first reproduction method and a second reproduction method that is different in terms of directivity of reproduced sound from the first reproduction method in accordance with a result of the comparison.

  • Patent number: 10068620
    Abstract: In order to affect the mood of a vehicle operator (for example, to increase attentiveness), embodiments of the invention automatically sequence appropriate audio cues into the sound playback from a vehicle's sound system. These cues represent events related to the vehicle or taking place in the vicinity of the vehicle, and can be modulated or effected so as to better convey the vehicle event. These cues may also be part of a coherent soundscape representing a fantasy scenario, such as motocross, sailing, or stand-up paddle boarding. Both the soundscape and the mapping of vehicle events to sound cues are configurable by the user.

  • Patent number: 10056093
    Abstract: A first encoding unit generates a first encoded signal by encoding a component within a first band in a voice signal. A frequency shifting unit shifts the frequency of a component within a second band in the voice signal, the second band having a frequency higher than that of the first band, to the frequency of a component within the first band. A second encoding unit generates a second encoded signal by encoding the component whose frequency has been shifted in the frequency shifting unit. An output unit outputs both the first encoded signal generated in the first encoding unit and the second encoded signal generated in the second encoding unit.

  • Patent number: 10046602
    Abstract: In a general aspect, a system includes circuitry for providing an engine harmonic scaling module and a summer. The engine harmonic scaling module is configured to receive a torque signal and a throttle signal, process the torque signal to generate a calibrated torque value, process the throttle signal to generate a throttle percentage value, determine a control parameter based on an examination of the calibrated torque value and the throttle percentage value, determine, based on the control parameter, a harmonic-specific scaling factor for each of one or more engine harmonic signals of a plurality of engine harmonic signals, and apply the corresponding harmonic-specific scaling factor to each of the one or more engine harmonic signals to generate corresponding scaled engine harmonic signals. The summer is configured to generate, from the scaled engine harmonic signals, a combined engine harmonic signal.

  • Patent number: 9994149
    Abstract: A sound transmitting system for a motor vehicle has a sound generator (2) and a sound-conducting first sound duct (6). The first sound duct (6) has a proximal end (7) connected to the sound generator (2) to transmit sound and a distal end (21) facing away from the proximal end (7) and via which a sound from the generated sound enters a passenger compartment (19) or external region (20) of a bodywork (26) of the motor vehicle (12). To bring about a specific sound characteristic of the resulting sound, a first length (L1) of the first sound duct (6) and/or a first diameter (D1) of the first sound duct (6) and/or a first cross-sectional area (Q1) of the first sound duct (6) are/is adapted as a function of the generated sound.
