Exploiting correlations in the audio, several works in the past have demonstrated the ability to automatically match and synchronize User Generated Recordings (UGRs) of the same event. Considering a small number of synchronized UGRs, we formulate in this paper simple linear audio mixing approaches to combine the available audio content. We use data from two different public events to perform a comparative...
The presence of reflecting surfaces inside an enclosure is generally known to have an adverse effect in acoustic source localization and Direction of Arrival (DOA) estimation performance. In this paper, we focus on the problem of indoor multi-source DOA estimation along the horizontal plane, considering a circular sensor array which is placed just in front of one of the vertical walls of the room...
We present a method for real-time detection and classification of impact sounds — relying solely on spatial features — that exploits the difference in the location of each impacted structure. Using a compact sensor array, we formulate the classification problem in terms of an undetermined source separation process where we assume that the linear mixing model can be learned through a training phase...
