# Direct MSE mode estimates LPC parameters without using an approximation of
# a Gram matrix using Toeplitz auto-correlation matrix.  As a result, direct
# MSE mode is not affected by a boundary condition so this doesn't necessitate
# a window function, and tuning of it.  As a drawback, the computational cost
# increases even with skipping the computation for window functions.  This
# feature is intended to be used for providing a reference data points when
# tuning window functions.
