- W77698045 abstract "ABSTRACTBlind source separation algorithms typically involve decorrelat-ing time-aligned mixture signals. The usual assumption is that allsources are active at all times. However, if this is not the case, weshow that the unique pattern of source activity/inactivity helps sep-aration. Music is the most obvious example of sources exhibitingrepetitive structure because it is carefully constructed. We presenta novel source separation algorithm based on spatial time-time dis-tributions that capture the repetitive structure in audio. Our methodoutperforms time-frequency source separation when source spec-tra are highly overlapping.1. INTRODUCTIONSource separation techniques attempt to decompose a set of time-aligned mixture signals (e.g., a song) into their constituent sourcesignals (e.g., instrument tracks). The usual assumption is that allsources are active at all times. However, many sources exhibitrepetitive structure in the form of activation patterns. We utilizethis structure in order to separate sources.As a motivating example, consider a repeating source such as abell tower or public address system that obscures the separation ofother local signals such as people talking. Because the bell towerchimed an hour ago among a different mix of sounds, we expect tobetter separate it in the current instance, e.g., either by producing acleaner recording of the bells or by removing their contribution tothe mixture. A bell tower sounds very similar every time it chimeswhether or not the exact melody is duplicated. We identify when asource repeats itself and use this to separate it from a mixture. Thisis in contrast to blind source separation (BSS) techniques that uti-lize correlations between mixtures computed globally on an entiresignal or locally at different time or time-frequency points. Thesetechniques decorrelate time-aligned mixture signals, whereas wedecorrelate between mixtures at different points in time.In general, BSS attempts to separate N source signals from Mmixtures by estimating the sources and mixing matrix according tothe following:x(t) = As(t), (1)where x = [x" @default.
