Abstract: This application discloses an audio data processing method and apparatus, and relates to the field of multimedia technologies. The method includes: obtaining m (m is an integer greater than or equal to 2) audio clips; determining m−1 pieces of transition audio information based on the m audio clips; and generating target medley audio based on the m audio clips and the m 1 pieces of transition audio information. The m−1 pieces of transition audio information are used to splice the m audio clips. First transition audio information in the m−1 pieces of transition audio information is used to splice a first audio clip and a second audio clip that are sorted consecutively in the m audio clips. Sorting of the m audio clips is a medley composition order of the m audio clips.

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.

Abstract: This application discloses an audio signal processing method and apparatus, and belongs to the field of audio signal processing technologies. The method includes: obtaining a plurality of sub-bands of an audio signal and a scale factor of each sub-band; determining, based on the scale factors of the plurality of sub-bands, a reference value used for shaping a spectral envelope of the audio signal; and shaping the spectral envelope of the audio signal by using the reference value as a baseline, to obtain an adjustment factor of each sub-band corresponding to a shaped spectral envelope. The adjustment factor is used to quantize a spectral value of the audio signal, and/or the adjustment factor is used to dequantize a code value of the spectral value. In this application, compression efficiency of encoding an audio signal is improved while sound quality is ensured.

Abstract: This application relates to the field of human-computer interaction, and provides a virtual keyboard processing method. The method is applied to an electronic device, where the electronic device is provided with a display. The method includes: selecting, in response to a detected first gesture operation, a first type of virtual keyboard corresponding to the first gesture operation from a plurality of types of virtual keyboards, where virtual keys included in different types of virtual keyboards in the plurality of types of virtual keyboards are not completely the same; and displaying the first type of virtual keyboard by using the display. More virtual keys are provided for a user by different types of virtual keyboards. This improves flexibility of a process in which the user enables the virtual keyboard, and helps provide more abundant virtual keys, so that an additional physical keyboard does not need to be provided.

Abstract: An embodiment provides a feedback method, applied to an electronic device provided with a touchscreen. The touchscreen is provided with a plurality of vibration feedback elements. The method includes detecting a first contact operation acting on the touchscreen, and obtaining first location information of a first contact point corresponding to the first contact operation, where the first location information corresponds to a first virtual key on a virtual keyboard. The method also includes if the first virtual key is an anchor point key, obtaining, from the plurality of vibration feedback elements, a first vibration feedback element that matches the first virtual key, and indicating the first vibration feedback element to emit a vibration wave, to prompt that the first virtual key is an anchor point key, so that the user can sense a location of the anchor point key. This can reduce difficulty in implementing touch typing on the touchscreen.
