Abstract

The embodiment of the invention relates to a dynamic regulation method and system for a Bluetooth audio. The method comprises the steps of: acquiring a current application scene, and configuring encoder parameters according to an acquired result; monitoring real-time communication quality, and if monitoring that the communication quality becomes poor, executing a strategy for avoiding sound jamming; and after executing the strategy, if monitoring that the communication quality is improved and when an improvement quantity of the communication quality reaches a preset threshold, starting up an internal timer, and according to timing of the internal timer, regulating an audio encoding rate and a radio frequency transmission power. According to the technical scheme provided by the invention, tone quality of the Bluetooth audio can be promoted, time delay can be reduced, connection stability can be reinforced and use time can be prolonged.

Description

technical field

[0001] The present application relates to the technical field of audio data processing, in particular to a dynamic adjustment method and system for Bluetooth audio. Background technique

[0002] Bluetooth audio based on A2DP (Advanced Audio Distribution Profile, Bluetooth audio transmission model protocol) is widely used, but there are currently some problems:

[0003] 1) The default SBC (Subband coding, subband coding) codec has poor sound quality;

[0004] 2) The audio and video are not synchronized due to the large delay, and the user experience for playing video and game scenes is poor;

[0005] 3) Poor connection stability: In a noisy environment, there is a lot of wireless interference, which leads to an increase in the bit error rate and audio lag.

[0006] 4) Fast power consumption: A considerable part of Bluetooth devices are embedded platforms with limited battery capacity, and some Bluetooth transmitter modules will choose to use the maximum tran...
