I have two sets of MFCC coeficients which I get with fftExtract utility from two wav audio files.
How can I compare this sets (matrix 271x13 and 551x13) if they are similar ?
Probably I should use EMD distance ... But Im sligthly lost in all this math and I dont know how to interpret its results .
How can I make from this distance matrix if both audio signals are similar or not - (Yes/Not)
I used following code for EMD :
function D = distEmd( X, Y ) Xcdf = cumsum(X,2); Ycdf = cumsum(Y,2); m = size(X,1); n = size(Y,1); mOnes = ones(1,m); D = zeros(m,n); for i=1:n ycdf = Ycdf(i,:); ycdfRep = ycdf( mOnes, : ); D(:,i) = sum(abs(Xcdf - ycdfRep),2); end
