    Abstract: Embodiments of this application disclose a noise cancellation apparatus and method. The noise cancellation apparatus includes a main control unit and a noise cancellation processing circuit. The main control unit determines a noise cancellation parameter based on a noise cancellation level index or a feature value for determining a matching degree between a headset and an ear canal of a user. The noise cancellation processing unit obtains an inverse phase noise of an ambient noise based on the noise cancellation parameter. After the inverse phase noise is mixed with a played downlink audio signal, the ambient noise can be canceled. In addition, because the noise cancellation parameter is determined from a preset noise cancellation parameter library based on the received or autonomously determined noise cancellation level index, instead of being uniformly configured, a noise cancellation level can be flexibly adjusted.

    Abstract: An audio coding method and apparatus are provided. The audio coding method includes: obtaining first audio data; obtaining a target bit rate and a Bluetooth packet type, where the target bit rate and the Bluetooth packet type correspond to a current status of a Bluetooth channel; obtaining one or more of a bit pool parameter set, a psychoacoustic parameter set, and a spectrum bandwidth parameter set by using a neural network obtained through pre-training based on the first audio data, the target bit rate, and the Bluetooth packet type; and coding the first audio data based on one or more of the bit pool parameter set, the psychoacoustic parameter set, and the spectrum bandwidth parameter set to obtain a to-be-sent bit stream. The status of the Bluetooth channel can be adaptively matched, and continuous audio listening experience is provided when audio quality is maximally ensured.

    Abstract: A rendering method and a related device are disclosed, and may be applied to a scenario such as production of music or film and television works, or the like. The method may be performed by a rendering device, or may be performed by a component (for example, a processor, a chip, a chip system, or the like) of a rendering device. The method includes: obtaining a first single-object audio track based on a multimedia file, where the first single-object audio track corresponds to a first sound object; determining a first sound source position of the first sound object based on reference information; and performing spatial rendering on the first single-object audio track based on the first sound source position, to obtain a rendered first single-object audio track.

    Abstract: Embodiments of this application provide an audio data processing method and apparatus, and a sound box system, which are related to the field of audio technologies, and improve sound quality of an audio playing device. The sound box system includes a full-frequency sound box and a low-frequency sound box. The full-frequency sound box is physically connected to the low-frequency sound box by using a first fastening part of the full-frequency sound box and a second fastening part of the low-frequency sound box. Furthermore, the full-frequency sound box communicates with the low-frequency sound box by using a first communication part of the first fastening part and a second communication part of the second fastening part, where the first fastening part and the second fastening part are a group of paired connection parts, and the first communication part and the second communication part are a group of paired communication parts.

    Abstract: Embodiments of this application disclose a noise cancellation apparatus and method. The noise cancellation apparatus includes a main control unit and a noise cancellation processing circuit. The main control unit determines a noise cancellation parameter based on a noise cancellation level index or a feature value for determining a matching degree between a headset and an ear canal of a user. The noise cancellation processing unit obtains an inverse phase noise of an ambient noise based on the noise cancellation parameter. After the inverse phase noise is mixed with a played downlink audio signal, the ambient noise can be canceled. In addition, because the noise cancellation parameter is determined from a preset noise cancellation parameter library based on the received or autonomously determined noise cancellation level index, instead of being uniformly configured, a noise cancellation level can be flexibly adjusted, thereby improving a noise cancellation effect and user experience.

    Abstract: Active noise cancellation method is provided, including: when the headset is in an ANC working mode, obtaining a first group of filtering parameters, and performing noise cancellation by using the first group of filtering parameters. The first group of filtering parameters is one of N1 groups of filtering parameters prestored in the headset. The N1 groups of filtering parameters are respectively used to perform noise cancellation on ambient sound in N1 leakage states. The N1 leakage states are formed by the headset and N1 different ear canal environments. In a current wearing state of the headset, for same ambient noise, noise cancellation effect obtained when the first group of filtering parameters is applied to the headset is better than noise cancellation effect obtained when another filtering parameter in the N1 groups of filtering parameters is applied to the headset. N1 is a positive integer greater than or equal to 2.

In those embodiments, a primary device can send networking information to a plurality of secondary devices, and the primary device has a permission to manage the cooperative network. The primary device can receive networking confirmation information sent by the plurality of secondary devices; and send configuration information to the plurality of secondary devices separately. The configuration information can be used to instruct to switch, based on a preset management permission switching mechanism when the primary device becomes abnormal or the primary device exits from the cooperative network, the permission to manage the cooperative network. The primary device can clear the secondary device from the cooperative network the secondary device becomes abnormal. In this way, robustness of the cooperative network can be improved.
