Audacity is one way. Another real fast way to extract audio from video is to upload it to youtube and use: https://ytmp3.cc/
There are not a thousand of advertisement pop up windows opening and hiding the original website. And there is no need to try to convert file many time till we see something is downloading and no need to press that mp3 button many times. Yes, i mean sites like savido or tubeoffline.
And i did not found any malware on downloaded file. I should check again with virustotal.com site ;-)
