% Usage SNR = demoAAC2(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
AACSeq2 = AACoder2(fNameIn);
decodedAudio = iAACoder2(AACSeq2, fNameOut);
[audioData, ~] = audioread(fNameIn);
SNR = snr(audioData(1025:end-1378, :), audioData(1025:end-1378, :) - decodedAudio(1025:length(audioData)-1378, :));
