Abstract:
We attempt to give an overview of current research in blind separation of convolutive mixing of signals, concentrating on audio signals, and methods applicable thereof. We briefly enumerate some application areas, we present two possible taxonomies of separation methods, one based on system parametrizations, the other on different criteria to solve the problem. We wade through the literature following these taxonomies. We also discuss what might yet be missing in the current research. 1. INTRODUCTION We presuppose familiarity with the concepts of Independent Component Analysis (ICA) and Blind Signal Separation (BSS). If this is not the case the reader is advised to refer to [1, 8, 15, 20, 37]. BSS seemingly has a large number of potential applications in the audio realm. The generic application is, of course, separation of simultaneous audio sources in reverberating or echoing environment, that is, in a natural environment, for example, inside a room. We will enumerate here only a fe...
