%Implementation of WHAT?? //TODO!!

% 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);

SNR = sum(10*log10((sum(audioData(1:length(decodedAudio), :)) .^ 2)./ ...

|
(sum(audioData(1:length(decodedAudio), :) - decodedAudio) .^ 2)));
