Update to ICASSP 2013 benchmark

function [H1H2, H2H4] = func_GetH1H2_H2H4(H1, H2, H4, Fs, F0, F1, F2, B1, B2)
% [H1H2, H2H4] = func_GetH1H2_H2H4(H1, H2, H4, Fs, F0, F1, F2, B1, B2)
% Input:  H1, H2, H4, vectors
%         Fs - sampling frequency
%         F0 - vector of fundamental frequencies
%         Fx, Bx - vectors of formant frequencies and bandwidths
% Output: H1A1, H1A2, H1A3 vectors
% Notes:  Function produces the corrected versions of the parameters. They
% are stored as HxHx for compatibility reasons. Use func_buildMData.m to
% recreate the mat data with the proper variable names.
% Also note that the bandwidths from the formant trackers are not currently
% used due to the variability of those measurements.
