Title:
METHOD AND APPARATUS FOR EVALUATING AUDIO SIGNAL LOSS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/253054
Kind Code:
A1
Abstract:
The present disclosure relates to the field of audio signal processing and provides a method and an apparatus for evaluating audio signal loss, and a storage medium, the method being used in an electronic apparatus, and comprising: performing compression processing on an original audio signal to acquire a compressed audio signal corresponding to the original audio signal (S110); performing decompression processing on the compressed audio signal to acquire a decompressed audio signal corresponding to the compressed audio signal (S120); acquiring the cosine similarity between the decompressed audio signal and the original audio signal (S130); and, on the basis of the cosine similarity, acquiring an evaluation score of the loss of the original audio signal (S140). By means of establishing a general audio signal evaluation rule, the degree of loss of audio signals during processing can be evaluated, facilitating the analysis and determination of audio signals.
