%RELANOIBORRA2019 Modulation filterbank (based on DRNL)
%
%   Usage: out = relanoiborra2019(insig_clean, insig_noisy, fs, varargin)
%          out = relanoiborra2019(insig_clean, insig_noisy, fs, flow, fhigh, varargin)
%          [out, clean, noisy] = relanoiborra2019([..])
%
%   Input parameters:
%     insig_clean  :  clean speech template signal
%     insig_noisy :  noisy speech target signal
%     fs         :  Sampling frequency
%     flow       :  lowest center frequency of auditory filterbank
%     fhigh      :  highest center frequency of auditory filterbank
%     N_org      :  length of original sentence. Will be double the length 
%                   of 'insig_clean' if not provided. 
%     sbj        :  subject profile for drnl definition. default: 'NH' 
%
%   Output parameters:
%     out           : correlation metric structure
%
%   This script builds the internal representations of the template and target signals
%   according to the CASP model (see references).
%   The code is based on previous versions of authors: Torsten Dau, Morten
%   Leve Jepsen, Boris Kowalesky and Peter L. Soendergaard.
%   The model has been optimized to work with speech signals, and the
%   preprocesing and variable names follow this principle. The model is
%   also designed to work with broadband signals. In order to avoid undesired
%   onset enhancements in the adaptation loops, the model expects to recive a
%   prepaned signal to initialize them.
%
%
%   The out structure has the following fields:
%
%     .dint       correlation values for each modulation band
%
%     .dsegments  correlation values from each time window and mod. band
%
%     .dfinal    f inal (averaged) correlation
