Segregating Complex Sound Sources through Temporal Coherence
Figure 2
Stream segregation of tone sequences and complexes.
Top row of panels represent the "mixture" audio whose two segregated streams are depicted in the middle and bottom rows. (A) The classic case of the well-separated alternating tones (top panel) becoming rapidly segregated into two streams (middle and bottom panels). (B) Continuity of the streams causes the crossing alternating tone sequences (top) to bounce maintaining an upper and a lower stream (middle and bottom panels). (C) Continuity also helps a stream maintain its integrity despite a transient synchronization with another tone. (D) When a sequence of tone complexes becomes desynchronized by more than 40 ms (top panel), they segregate into different streams despite a significant overlap (middle and bottom panels).
