function SNR = demoAAC1(fNameIn, fNameOut)
%Function that demonstrates usage of the level 1 code
%   Usage SNR = demoAAC1(fNameIn, fNameOut), where:
%       Inputs
%       - fNameIn is the filename and path of the file to encode
%       - fNameOut is the filename and path of the file that will be
%       written after decoding
%
%       Output
%       - SNR is the signal to noise ration computed after successively
%       encoding and decoding the audio signal

    AACSeq1 = AACoder1(fNameIn);
    decodedAudio = iAACoder1(AACSeq1, fNameOut);

    [audioData, ~] = audioread(fNameIn);
