Abstract
Localization of audio sources is an important research problem, e.g., to facilitate noise reduction. In the recent years, the problem has been tackled using distributed microphone arrays (DMA). A common approach is to apply direction-of-arrival (DOA) estimation on each array (denoted as nodes), and then map the DOA estimates to a location. In practice, however, the individual nodes contain few microphones, limiting the DOA estimation accuracy and, thereby, also the localization performance. We investigate a new approach, where range estimates are also obtained and utilized from each node, e.g., using time-of-flight cameras. Moreover, we propose an optimal method for weighting such DOA and range information for audio localization. Our experiments on both synthetic and real data show that there is a clear, potential advantage of using the joint audiovisual localization framework.
