Irregular Circular Array Results (Real Measurements)

Home

In this page we show results corresponding to reproduction of a single source when using the deep learning-based model presented in [1], denoted as CNN, the Model-based rendering technique presented in [2] denoted as MR, the pressure-matching approach [3] denoted as PM and the adaptive wavefield synthesis technique[4], denoted as AWFS. We also present results related to an adaptive version of MR denoted AMR. We consider a regular loudspeaker array of 64 elements and randomly remove 16,32, and 48 loudspeakers, ending with a 48,32,16 element array, respectively. The data presented here is generated through real measurements of Room Impulse Responses contained in [5].
