The magnitude of rab[m] is used to discriminate edit points. Note that the correlation coefficient differs from its conventional definition in two ways: First, subtracting the arguments by its mean is omitted, since the prior k-th order difference attenuates the low-frequency contents of the operands sufficiently. Second, normalization by the variance of the signals is not performed. Therefore, it appears sensible to incorporate the power of the audio signal into the determination of discontinuities. The length of the step function used to model the discontinuity as well as the order k of the difference operator influence the performance of discontinuity detection. Cooper states that a best detection can be provided with a second order difference and a step function of length 80.
