WitrynaModified Discrete Cosine Transform (MDCT) The MDCT is a linear orthogonal lapped transform, based on the idea of time domain aliasing cancellation (TDAC). It was first introduced in [ 7 ], and further developed in [ 8 ]. MDCT is critically sampled, which means that though it is 50% overlapped, a sequence data after MDCT has the same … http://ftj.agh.edu.pl/~stegowski/rozne/m_skrypcik.pdf
