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

we can use ffmpeg to get the duration of any video or audio files.

To install ffmpeg follow this link

import subprocess
import re

process = subprocess.Popen(['ffmpeg',  '-i', path_of_wav_file], stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
stdout, stderr = process.communicate()
matches = re.search(r"Duration:\s{1}(?P\d+?):(?P\d+?):(?P\d+\.\d+?),", stdout, re.DOTALL).groupdict()

print(matches['hours'])
print(matches['minutes'])
print(matches['seconds'])
