TypeError: time_stretch() takes 1 positional argument but 2 were given

Question

enter image description here

def stretch(data, rate=0.8):
    return librosa.effects.time_stretch(data, rate)

x = stretch(data)
plt.figure(figsize=(14,4))
librosa.display.waveplot(y=x, sr=sample_rate)
Audio(x, rate=sample_rate)

enter image description here

Above is my function and error when I tried to run it

I tried passing the data and rate into the stretch function but returns the error as shown. As you can see, it should take the data and rate then return the stretched file

Answer 1

This error occurs because you need set implicit rate parameter , because the definition of function has additional parameter, then parameter rate

def time_stretch(y: np.ndarray, *, rate: float, **kwargs: Any) -> np.ndarray:

def stretch(data, rate=0.8):
    return librosa.effects.time_stretch(data, rate=rate)
