Abstract: Embodiments of the present disclosure provide a headset control method, a headset, a headset control apparatus, and a related storage medium. The method includes: collecting environment information, and determining key sound detection sensitivity based on the environment information; performing key sound detection in the environment information based on the key sound detection sensitivity; and if a key sound exists in the environment information, adjusting the headset to a hear through mode, or playing the key sound. The headset collects the environment information, determines the key sound detection sensitivity based on the environment information, and performs key sound detection in the environment information based on the key sound detection sensitivity. If the key sound exists, the headset is adjusted to the hear through mode, or the key sound is played. In this solution, the key sound detection sensitivity corresponding to the environment information is determined based on the environment information, to perform key sound detection.

Abstract: Example data generation methods and apparatuses are provided. One example method includes obtaining, by a data generation apparatus, spatial object information. The data generation apparatus can then generate content information for describing the spatial object. The data generation apparatus can then generate azimuth information based on the spatial object information, where the azimuth information indicates an azimuth of a spatial object relative to the data generation apparatus. The data generation apparatus can then generate, based on the azimuth information and the content information, spatial sound data for playing a spatial sound, where a position of a sound source of the spatial sound corresponds to the azimuth information.

Abstract: The present invention provides a method and a device for identifying and obtaining AMBE encoding and decoding rate information in an SDP. The method for identifying the AMBE encoding and decoding rate information in the SDP includes: setting an SDP, which specifically includes: in an m attribute line of the SDP, using a payload type PT value to describe AMBE encoding and decoding, and in an fmtp attribute of an a attribute line of the SDP, identifying, in a format field, a PT value same as that of the m attribute line, and identifying AMBE encoding and decoding rate information in a format specific parameter field; and sending the set SDP to a peer end. The method and the device for identifying and obtaining the AMBE encoding and decoding rate information in the SDP provided by the present invention can implement automatic rate switching in a bearer plane.

Abstract translation: 本发明提供一种用于在SDP中识别和获取AMBE编码和解码速率信息的方法和装置。 用于识别SDP中的AMBE编码和解码速率信息的方法包括：设置SDP，其特别地包括：在SDP的m属性行中，使用有效载荷类型的PT值来描述AMBE编码和解码，并且在fmtp 属性，在格式字段中识别与m属性行相同的PT值，以及在格式特定参数字段中识别AMBE编码和解码速率信息; 并将设置的SDP发送到对端。 本发明提供的SDP中识别和获取AMBE编码和解码速率信息的方法和装置可以在承载平面中实现自动速率切换。

Abstract: The present discloser relates to a method for active noise cancellation. An example method includes: capturing an ambient sound to determine an ambient audio signal; and determining a working status, determining at least one corresponding wanted signal based on the working status, and then removing the at least one wanted signal from the ambient audio signal, to obtain a reference signal, where the wanted signal includes content of interest. The example method further includes determining a to-be-played signal based on the reference signal.
