Steps/Code to Reproduce

y, sr = librosa.load(‘~/PycharmProjects/MA/Roland-JV-2080-PizzicatoStr-C5.wav/’)

hop_length = 512

mfccs = librosa.feature.mfcc(y=y, sr=sr, hop_length=hop_length, n_mfcc=13)

plt.figure(figsize=(10, 4)) librosa.display.specshow(mfccs, x_axis=‘time’) plt.colorbar() plt.title(‘MFCC’) plt.tight_layout()

Expected Results

Plot of MFCCs

Actual Results

Error message and no plot:
