Problems solved by technology

[0004] However, the playback device may be affected by the temperature and produce zero drift phenomenon, resulting in a change in the frequency of the oscillating signal, that is, the sampling frequency of the playback device changes, the second sampling frequency is not equal to the first sampling frequency, electronic equipment and playback equipment Out of sync, which affects the playback effect of audio data

Abstract

The invention provides an audio playing method and device, playing equipment and a storage medium, and belongs to the technical field of electronics. The method comprises the following steps: detecting the number of audio sampling points in a cache region; when the detected first number does not belong to a preset number range, adjusting a preset first frequency division parameter to obtain a second frequency division parameter; and generating a second sampling frequency based on the second frequency division parameter, and extracting the audio sampling point from the cache region according tothe second sampling frequency to play. According to the invention, when the electronic equipment and the playing equipment are not synchronous, the frequency division parameter can be adjusted to adjust the sampling frequency of the playing equipment, and the difference between the sampling frequency of the playing equipment and the first sampling frequency of the electronic equipment is reduced,so that the playing equipment and the electronic equipment tend to be synchronous, and the playing effect of the audio data is not influenced.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, and in particular to an audio playback method, device, playback device and storage medium. Background technique [0002] With the development of electronic technology and the increasing demand of users for audio playback effects, there are currently many playback devices used to play audio data, such as smart speakers, etc. These playback devices can be connected to electronic devices to play audio data in electronic devices , to improve the playback effect of audio data. [0003] In related technologies, the electronic device establishes a connection with the playback device, and the electronic device decodes the audio data to obtain audio sampling points, and sends the obtained audio sampling points to the playback device according to the first sampling frequency, and the playback device stores them in a buffer area. And the playback device generates an oscillating signal, divides...
