Abstract: A core having enhanced ID stiffness is provided. The core includes inner, intermediate, and outer wall zones. The intermediate zone is spring-like in that it minimizes deformation of the inner zone from a radial deflection of the outer zone by absorbing at least some of the deformation. Similarly, the intermediate zone minimizes deformation of the outer zone from a radial deflection of the inner zone by absorbing at least some of the deformation. The intermediate zone includes at least first and second intermediate layers and one or more intermediate support layers. The first and second layers include a number of plies and gaps that are offset from each other, i.e. the plies of the first layer are radially aligned with the gaps of the second layer. The intermediate support layers are between the first and second layers and extend radially across the gaps of the first and second layers.

Abstract: A method for determining an acceptacle splice point is provided to facilitate splicing of a first segment of an audio signal to a second segment thereof. According to the method, an audio signal is converted into a sequence of samples and first and second edit points are selected along the sequence. The first edit point represents a nominal ending point of the first audio segment, and the second edit point represents a nominal starting point of the second audio segment. According to the method, a plurality of samples in a correlation window following the first edit point are weighted and correlated with a plurality of weighted samples in a correlation window following the second edit point for each position of the second edit point. The position of the second edit point is then shifted to the next sample in the sequence. After the correlation is calculated for each position of the second edit point, the location of an acceptable splice point can be determined.
