| description | The invention relates to a method for performing dynamic range adjustment of spatial audio objects and an audio processing system. The method comprises obtaining (step S1) a plurality of spatial audio objects (10), obtaining (step S2) at least one rendered audio presentation of the spatial audio objects (10), and determining (step S3) signal level data associated with each presentation audio channel of the set of presentation audio channels. The method further comprises obtaining (step S31) a threshold value and, for each time period, selecting (step S4) a selected presentation audio channel associated with the highest or lowest signal level, determining (step S5) a gain based on the threshold value and a representation of the signal level of the selected audio channel, and applying (step S6) the gain for each time period to the corresponding time period of the spatial audio object.
本公开涉及用于执行空间音频对象的动态范围调整的方法和音频处理系统。该方法包括获得(步骤S1)多个空间音频对象(10)，获得(步骤S2)空间音频对象(10)的至少一个被渲染的音频呈现，以及确定(步骤S3)与呈现音频通道集合中的每个呈现音频通道相关联的信号电平 |
