Webb28 okt. 2024 · You can either keep the MFCCs as a 1-d vector of size (a*b,1) or as a 2-d vector/matrix of size (a,b) depending upon how you want to compute the correlation among them. Then you can proceed with computing the correlation using corr or corrcoef. Please have a look at this thread if you want to compute the correlation between two matrices. … Webbför 2 dagar sedan · So I'm trying to replicate the process of obtaining MFCC from an audio file. So far I have obtained the Mel Spectrogram, and the last step is to perform Discrete Cosine Transform to the Mel Spectrogram. I've tried using scipy's dct() function to the spectrogram but it's still not quite what I'm looking for.
