Multi-audio-stream sound mixing playing method and system based on main and auxiliary sound channels

The invention relates to the technical field of audio playing, and provides a multi-audio-stream sound mixing playing method and system based on main and auxiliary sound channels, and the method comprises the steps: decoding audio streams corresponding to all applications based on the consistency requirement of sound mixing playing, then uniformly calculating the target output volume of each type of audio streams according to a preset low-voltage strategy and attribute information, so that independent sound mixing of each application is not needed, the application development amount is reduced, the audio processing error rate is reduced, and the sound mixing effect rate is improved; and finally, subjecting all types of audio streams uniformly adjusted to sound mixing, and transmitting the obtained sound mixing data to a DSP module for audio output. Thus, sound mixing is performed at the real playing moment of the audio streams, so that the consistency of mixed audio playing can be further improved, and better
