How to load an audio file using Librosa?

[sayantan99]

import librosa as lr

def test():

(signal, rate)= lr.load("heart.wav", sr=None)

return rate

But I am getting this error. Though my audio file and python file are in the same folder.

UserWarning: Could not import scikits.samplerate. Falling back to scipy.signal
