    • Example embodiments disclosed herein relate to a estimation of reverberant energy components from audio sources. A method of estimating a reverberant energy component from an active audio source (100) is disclosed. The method comprises determining a correspondence between the active audio source and a plurality of sample sources by comparing one or more spatial features of the active audio source with one or more spatial features of the plurality of sample sources, each of the sample sources being associated with an adaptive filtering model (101); obtaining an adaptive filtering model for the active audio source based on the determined correspondence (102); and estimating the reverberant energy component from the active audio source over time based on the adaptive filtering model (103). Corresponding system (800) and computer program product (900) are also disclosed.
    • 本文公开的示例性实施例涉及从音频源估计混响能量分量。 公开了一种从有源音频源(100)估计混响能量分量的方法。 该方法包括通过将活动音频源的一个或多个空间特征与多个采样源中的一个或多个空间特征进行比较来确定活动音频源与多个采样源之间的对应关系,每个采样源与 自适应滤波模型(101); 基于所确定的对应关系(102)获得所述有源音频源的自适应滤波模型; 以及基于所述自适应滤波模型(103)估计来自所述有源音频源的混响能量分量。 还公开了相应的系统(800)和计算机程序产品(900)。
