RuntimeWarning in estnoisems function

[newrlan]

Hi, I found a mistake when run VAD on a single. If the pSpectrum value has only zeroes on first string, the result of estnoisem function return table with np.nan. I added strings

begin = 0
while begin < nFrames and np.all(pSpectrum[begin,:] == 0.0):
        begin += 1
p=pSpectrum[begin,:]  

to redefinition p valuation and run for cycle in range(begin, nFrames).

That improve a crashing of code, but hold that mistake

Voice_Activity_Detector/utils/estnoise_ms.py:108: RuntimeWarning: divide by zero encountered in double_scalars
  acb=(1+(sum(p) / sum(pSpectrum_t)-1)**2)**(-1)    # alpha_c-bar(t)  (9)

Yes, I also think there is a problem on that part. Initial 'p' should be not zero or that big value comparing other frames.

Thank you for your feedback.

@proposition does that fix the crashing of code ??
iam having the same issue

@krupalraj yes, I did this, but I've not saved the code version.

The problem appears when your audio file have zero parts. The simplest way to avoid the problem is to cut off the zero regions.

sure,Thanks @proposition
