Fix my matlab code on audio fingerprinting project

Hello Freelancers! I am working on a matlab project specifically on audio fingerprinting. I am interested in some help on the part of fingerprint extraction. I've done some things on the track but unfortunately it's not working properly so I'm looking for someone to help me. For my work, I am based on the paper that I attach to you (pdf file). The part I'm dealing with is III.A. Feature Extraction. I send you also the matlab files. EVERYTHING IS IN THE RAR FILE OR ON THE FOLLOWING LINK: [login to view URL] A little clarification: the error I'm finding is that to get the fingerprints even from a 30s song it takes unjustifiably long, and the most important thing when I get the fingerprints for part of this song (eg 8s) is not recognizable because I do not have the same fingerprints for that part so it does not find a match. Thank you very much for your time, and looking forward to working with you :)
