This is the number of sample fames (integer) of delay introduced in
compression and decompression processing. These numbers are usually
different for compression versus decompression. This is caused by filter
operations that convolve a N past input samples with a filter M-
coefficient array to create N+M-1 output samples. The filtered signal
contains more samples than the unfiltered signal. the output signal is
offset by DDDDMMMM____AAAAUUUUDDDDIIIIOOOO____CCCCOOOODDDDEEEECCCC____FFFFIIIILLLLTTTTEEEERRRR____DDDDEEEELLLLAAAAYYYY samples from the first sample thus
