FIG. 9 is an illustration of a reference audio signal 902 edited to add a segment, resulting in a target audio signal 904. For example, a 10-second-long portion is inserted into the reference signal 902 at 1:08 to produce the target signal 904. FIG. 10A is an illustration of the distances between the respective temporally ordered segments of the two audio signals of FIG. 9. FIG. 10B is an illustration of the longest common subsequence identified within the pair of audio signals of FIG. 9. The horizontal line in FIG. 10B represents the insertion into the reference signal 902.

FIG. 11 is an illustration of a reference audio signal 1102 edited to replace a segment, resulting in a target audio signal 1104. For example, a 10-second-long portion from 1:08 to 1:18 is replaced. FIG. 12A is an illustration of the distances between the respective temporally ordered segments of the two audio signals of FIG. 11. FIG. 12B is an illustration of the longest common subsequence identified within the pair of audio signals of FIG. 11. The thin diagonal connecting the two thick diagonals represents the substitution of the portion of the reference signal 1102.
