Webb2.2 Feature Extraction Using the librosa python library, four features of the audio ﬁles were extracted. These features are Mel frequency cepstral coefﬁcients (MFCC), Short-Time Fourier Transform (STFT), Chroma, and Contrast. • Mel frequency cepstral coefﬁcients (MFCC): It is a widely used feature in automatic sound recognition. WebbMFCC is employed in this technique in order to extract features. The MFCC method requires applying a DFT onto every window, taking the logarithm of the amplitude ...
