Get .wav file length or duration

Question

I\'m looking for a way to find out the duration of a audio file (.wav) in python. So far i had a look at python wave library, mutagen, pymedi

Answer 1

Let,T be the duration between 2 consecutive samples. So, we can write t = nT or t = n/Fs.

from scipy.io import wavfile
Fs, data = wavfile.read('filename.wav')
n = data.size
t = n / Fs
