摘要： A system and method are disclosed for effective and simple stereo widening over arbitrarily-configured speakers and its real-time implementation. According to one embodiment, the system includes five processing units: (1) elevation processing unit; (2) side signal or difference signal processing unit; (3) center signal processing unit; (4) binaural signal processing unit; and (5) stereo limiter (to prevent the clipping) unit. Any of the five processing units may be included or omitted depending on the application. In general, embodiments of the present invention provide effective and simple stereo widening schemes with good audio quality results, but without having substantial requirements on the speakers' positional configuration. For example, the proposed schemes can apply to both symmetric and non-symmetric stereo loudspeakers.

摘要： A system is provided that produces haptic effects. The system receives an audio signal that includes a low-frequency effects audio signal. The system further extracts the low-frequency effects audio signal from the audio signal. The system further converts the low-frequency effects audio signal into a haptic signal by shifting frequencies of the low-frequency effects audio signal to frequencies within a target frequency range of a haptic output device. The system further sends the haptic signal to the haptic output device, where the haptic signal causes the haptic output device to output one or more haptic effects.

摘要： Systems, methods, and apparatus to filter audio are disclosed. An example method includes determining that an orientation of a playback device is one of (a) a first orientation and (b) a second orientation, the playback device including a first speaker and a second speaker and configuring the first speaker and the second speaker. In the example, configuring the first and second speakers includes, when the determined orientation is the first orientation, configuring a first audio filter to be applied to a first audio signal for the first speaker and configuring a second audio filter to be applied to a second audio signal for the second speaker. However, when the determined orientation is the second orientation, configuring the first and second speakers includes configuring a third audio filter to be applied to the first audio signal and the second audio signal.

摘要： When a correlation between an L channel and an R channel of a reproduction-target sound source is considerably high, virtual sound obtained from a reproduction signal is often more likely to be localized inside the head of a listener. A device includes: a correlation analysis unit (3) that analyzes a degree of correlation between a surround L channel signal (SL signal) and a surround R channel signal (SR signal); and an output signal control unit 4 that controls, based on the degree of correlation between the SL signal and the SR signal obtained as a result of the analysis performed by the correlation analysis unit (3), a ratio between: the signals outputted from a front L speaker (7) and a front R speaker (8); and the signals outputted from a near-ear L speaker (9) and a near-ear R speaker (10).

摘要： A spectral management system may be used in an audio system to receive and process audio signals having multiple distributed audio channels, such as a right, left, center, right side, left side, right rear and left rear channels. The spectral management system may separate and route a frequency range of audio content included in one or more of the distributed audio channels to other distributed audio channels. The separated and routed frequency range of audio content may be combined with audio content present on the other distributed audio channels to which the separated frequency range of audio content is routed. Separation, routing and combination may include bass audio content routing, mid-bass audio content routing, subwoofer audio content routing and treble audio content routing.

摘要： An apparatus including an air-conduction transducer and a bone conduction transducer. The air-conduction transducer is configured to convert a first frequency band component of an electrical audio signal into acoustic energy to be delivered to an ear canal of a user. The bone conduction transducer is configured to convert a second, at least partially different, frequency band component of the electrical audio signal into mechanical energy to be delivered to a skull of the user. The apparatus is configured to deliver both forms of the energies to the user at a substantially same time to provide a combined audio delivery result to the user.
