Bluetooth audio control method and device and computer readable storage medium

Abstract

The invention discloses a Bluetooth audio control method and device, and a computer readable storage medium, and the method comprises the steps: monitoring an audio playing request when a terminal device detects that the Bluetooth device is connected; then, if the audio playing request is received, determining a generation scene of the audio playing request; then, obtaining a time delay demand ofaudio playing according to the generation scene, and determining whether the time delay demand is lower than a preset time delay value or not; and finally, if the time delay demand is lower than the preset time delay value, carrying out soft coding processing on the audio to be sent through a Bluetooth protocol stack and sending the audio, and if the time delay demand is higher than the preset time delay value, carrying out hard coding processing through a processor and sending the audio. A user-friendly Bluetooth audio control scheme is realized, the balance problem of power consumption and time delay in the Bluetooth audio transmission process is solved, and the playing experience of the Bluetooth audio is enhanced.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a bluetooth audio control method, device and computer-readable storage medium. Background technique [0002] In the prior art, with the rapid development of terminal equipment technology, users have higher and higher real-time requirements for the sound of mobile games, and the realization of the common encoding format of the Bluetooth headset itself is a delayed sound transmission. The protocol itself is designed for scenarios such as listening to music and calling. These scenarios are not sensitive to sound delay. However, with the popularity of mobile games, users have more and more low-latency requirements for some special applicable scenarios such as game scenarios. high. [0003] Based on this low-latency requirement, if the mobile phone is connected to a Bluetooth headset to achieve low-latency sound effects, it is necessary to adjust the parameters of the Blue...

Problems solved by technology

Most mobile phones now use the ADSP (Advanced Digital Signal Processing) solution. Since ADSP is a hard-coded solution, it is difficult to set parameters for this. Therefore, it is impossible to conveniently perform Bluetooth packet sending interval parameters and packet size in the prior art. adjustment

The soft encoding is to directly hand over the audio data to the Bluetooth protocol stack, encode it by the Bluetooth protocol stack, and then transmit it through Bluetooth, and no longer need to be processed by the ADSP chip, so that all packet sending intervals, packet size, coding methods, etc. The parameters can be adjusted through the Bluetooth protocol stack, but the problem brought about by this is that the power consumption is high

[0004] Therefore, in the prior art, there is no suitable solution that can simultaneously solve the balance problem of power consumption and delay in the process of Bluetooth audio transmission.
