Title:
AUDIO PROCESSING METHOD AND APPARATUS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/212880
Kind Code:
A1
Abstract:
The present disclosure provides an audio processing method and apparatus, and a storage medium, which belong to the technical field of communications. The method comprises: determining metadata of each frame of audio data, wherein the metadata comprises at least one among absolute position information of an acoustic object, relative position information of the acoustic object, orientation information of the acoustic object, and a sound emission range of the acoustic object in the audio data; and acquiring an object audio signal on the basis of the metadata of the audio data. By means of using the method provided in the present disclosure, the data volume and transmission bandwidth of the metadata are reduced, the coding efficiency is increased, and it is ensured that a renderer can subsequently correctly render the orientation of an acoustic object and provide a correct spatial audio perception result without affecting a final decoding rendering effect. A hearing difference generated by different actual orientations of the acoustic object can be simulated, so that the rendering effect is improved.
