Abstract: An echo filtering method, an electronic device, a computer-readable storage medium, and an echo filtering apparatus are disclosed. The electronic device includes M microphones and N speakers. M and N are integers greater than 1. The method includes: obtaining N speaker signals corresponding to the N speakers (302); obtaining M microphone signals corresponding to the M microphones (304); and performing at least direct sound filtering on the N speaker signals and the M microphone signals to obtain a target signal (306). By using this method, better echo filtering effect can be obtained.

Abstract: This application provides example psychoacoustics-based audio encoding methods and apparatuses. One example method includes receiving audio data. The audio data can be decoded. Auditory feature information of a user can be obtained, where the auditory feature information includes at least one of the following: personal information, listening test result information, or frequency response curve information. A psychoacoustics model parameter of the user can be calculated based on the auditory feature information of the user, where the psychoacoustics model parameter includes at least one of the following: an intra-band masking parameter, a slope of a low-frequency inter-band masking line, a slope of a high-frequency inter-band masking line, or a human ear quiet threshold curve. The decoded audio data can be encoded based on the psychoacoustics model parameter of the user.

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.
