function x = iAACoder1(AACSeq1, fNameOut)
%Implementation of AAC decoder
%   Usage x = iAACoder1(AACSeq1, fNameOut), where:
%       Inputs
%       - fNameOut is the filename and path of the file that will be
%       written after decoding
%        - AACSeq1 is an array of structs containing K structs, where K is
%        the number of computed frames. Every struct of the array consists
%        of a frameType, a winType, chl.frameF which are the MDCT
%        coefficients of this frame's left channel, chr.frameF which are
%        the MDCT coefficients of this frame's right channel
%
%       Output
%       - x is an array containing the decoded audio samples

    % Initializes an array to hold the decoded samples
    decodedAudio(1024 * (length(AACSeq1) + 1), 2) = 0;
    % Initializes an array to hold both audio channels
