算法通过引人双层结构分层评估，第一步得到基本音质和空间声像得分，第二步

The algorithm uses an attractive two-layer structure for layered evaluation. The first step is to obtain the basic sound quality and spatial sound image scores, and the second step is to map the two indicators into the overall score, which not only improves the accuracy of the algorithm, but also makes the three-dimensional audio quality to be tested The situation is more clear, and the tester can understand the different effects of the audio processing technology on the basic sound quality and spatial sound image.

The first step is to get the scores of the basic sound quality and the spatial sound image, and the second step is to map the two indicators into the overall score, which can not only improve the accuracy of the algorithm, but also make the situation of the 3D audio quality to be tested more clear, so that the tester can understand the different effects of the audio processing technology on the basic sound quality and the spatial sound image.<br>

By introducing two-tier hierarchical evaluation, the algorithm obtains the basic sound quality and spatial sound image scores in the first step, and maps the two indicators into the overall score in the second step, which can not only improve the accuracy of the algorithm, but also make the situation of 3D audio quality to be tested clearer, so that testers can understand the different effects of the audio processing technology on the basic sound quality and spatial sound image.
