public class ShiftedDelta
extends AbstractDataProcessor

Shifted Delta. Stacked delta features computed across multiple speech frames. The SDC features are specified by a set of 4 parameters, n, d, p and k, where n is the input feature dimension to be used, d represents the time advance and delay for the delta computation, k is the number of blocks whose delta coefficients are concatenated to form the final feature vector, and P is the time shift between consecutive blocks.
