Extracting Reverberant Sound Using a Linearly Constrained Minimum Variance Spatial Filter

Microphone arrays are typically used to extract the direct sound of sound sources while suppressing noise and reverberation. Applications such as immersive spatial sound reproduction commonly also require an estimate of the reverberant sound. A linearly constrained minimum variance filter, of which...
