Abstract: An audio processing method includes determining an audio data source, registering an audio block service for the audio data source to obtain registration information of the audio block service, where the registration information of the audio block service includes identification information used for performing the audio block service on the audio data source, performing software decoding on the audio data source to obtain audio track data when it is determined, based on the identification information, that the audio data source needs to be blocked, and performing behavior analysis based on the audio track data. Hence, audio track data can be collected in a targeted manner, the collected audio track data is converted into text through speech recognition, and the text can be used for semantic analysis or internally-recorded audio recognition.

Abstract: A file sending method, a file receiving method, and related terminals, where a first terminal is configured to scan on a BLUETOOTH low energy (BLE) broadcast channel to obtain a broadcast packet from at least one second terminal, determine at least one discoverable second terminal based on the broadcast packet, determine a target terminal that is configured to receive a file and that is in the at least one discoverable second terminal, send a coupling request to the target terminal, establish a BLE coupling between the first terminal and the target terminal, and send WI-FI direct coupling parameters to the target terminal using a BLE data channel of the BLE coupling. The WI-FI direct is established between the first terminal and the target terminal.
