Webb5 apr. 2024 · Then, I looped through audio_files, loaded each mp3 file using librosa.load, and then calculated the MFCC. The issue is whenever I stop the loop before it finishes and try to print out the mfcc1 variable, it only outputs the last MFCC matrix it calculated. I need it to save all the MFCC data for each mp3 file it loops through.
