Abstract

The invention provides the improved advanced audio coding / decoding method of a wireless Bluetooth system. The method comprises the following steps that a main audio device carries out AAC partial decoding on the received audio signal of AAC coding; noiseless decoding, inverse quantization processing, and combined stereo decoding are performed on the received audio signal of AAC coding to obtain the audio signal of a decoded intermediate state; one path of the audio signal is selected from the audio signal of the decoded intermediate state obtained through AAC partial decoding to carry out AACpartial coding; quantitative processing and noiseless coding are performed on the one path of the selected intermediate state of audio signal to obtain the audio signal of AAC partial coding; and themain audio device forwards the audio signal of the AAC partial coding to a slave audio device through Bluetooth. The operand of the main audio device can be effectively reduced and the time delay of awhole system is decreased.

Description

technical field [0001] The invention relates to the technical field of bluetooth earphones, in particular to an improved advanced audio encoding / decoding method and system of a wireless bluetooth system. Background technique [0002] With the progress of society and the improvement of people's living standards, earphones and speakers have become indispensable daily necessities for people. Traditional wired earphones are connected to smart devices through wires, which restricts the wearer's movement, especially in sports situations. At the same time, the winding and pulling of the headphone cable, as well as the stethoscope effect all affect the user experience. Ordinary Bluetooth headsets cancel the connection between the headset and the smart device, but there is still a connection between the left and right ears. True Wireless Stereo (TWS) earphones and wireless speakers have emerged as the times require, and true wireless connections are realized through wireless transm...
