Abstract: Generating first map information, where the first map information includes information about a first reference object set, and the information about the first reference object set indicates a first identifier, in a geographic area, of each reference object in at least one reference object included in the first reference object set, and indicates a first position of each reference object in the at least one reference object. The first map information is generated, and the first map information indicates related information of each reference object in the first reference object set, to implement a manner of expressing the related information of the reference object more abundantly, so that maps provided by different map vendors may use reference objects in the first map information to perform position expression on an element or an event.

Abstract: The disclosure relates to an audio processing apparatus, comprising: a plurality of audio sensors, each audio sensor configured to receive a respective plurality of audio frames of an audio signal from an audio source, wherein the respective plurality of audio frames defines an audio channel of the audio signal; and a processing circuitry configured to: determine a respective feature set having at least one feature for each audio frame of each of the plurality of audio frames, wherein the plurality of features define a three-dimensional feature array; process the three-dimensional feature array using a neural network, wherein the neural network comprises a self-attention layer configured to process a plurality of two-dimensional sub-arrays of the three-dimensional feature array; and generate an output signal on the basis of the plurality of processed two-dimensional sub-arrays. Moreover, the disclosure relates to a corresponding audio processing method.
