Flowchart of the estimation and optimization of the SMC. The first iteration of a new sub-band s will use the globally estimated SMC from the initialization procedure as described in Section 4.2.2 as initial values for the search of its optimal values. The switch ensures that subsequent iterations will use the previously optimized (but not converged) values for a better optimization. When convergence is achieved, the next sub-band s+1 will again use the globally estimated SMC as initial values for the optimization
