RuntimeWarning: invalid value encountered in divide

Hey! Thanks again for creating this library :) I'm trying to use it to reduce background noise on 20ms chunks of streaming telephony audio before passing it to a voice activity detector.

To test it out, I ran the provided example code on a local wav file, but am getting the following error:

from scipy.io import wavfile
import noisereduce as nr
# load data
rate, data = wavfile.read("mywav.wav")
# perform noise reduction
reduced_noise = nr.reduce_noise(y=data, sr=rate)
wavfile.write("mywav_reduced_noise.wav", rate, reduced_noise)

noisereduce.py:306: RuntimeWarning: invalid value encountered in divide
  sig_mult_above_thresh = (abs_sig_stft - sig_stft_smooth) / sig_stft_smooth

Am I doing something wrong?

Woops, I forgot to reshape the data as mentioned in #71
