how to get the pulse width of an audio file in Python?

Question

I read a .wav file using the read function of the soundfile library in Python. I was wondering if there is any function to get the number of pulses of this signal, something like the pulsewidth function in Matlab.

If not, given that I did

[data,fs]=sf.read(wave)

I'm also trying something like this:

y=data2.count(data2>0.5)

but I'm getting this error:

AttributeError: 'numpy.ndarray' object has no attribute 'count'

Isn't pulse width the inverse of sampling rate? `data, samplerate = sf.read('existing_file.wav')` — LMC, Aug 30 '18 at 19:56
@LuisMuñoz each pulse can have a different duration, so nope :) — Contact-us Behind The Sciences, Aug 31 '18 at 07:11

I think scipy.signal.find_peaks can be of use to you.

With a numpy array as input, you can get the indices of the peaks, their widths ... etc
