Luckily, I was sent this cheapo model to review. And, I’m pleased to say, it’s pretty good! Comes with a reasonably long USB cord, and a pop-shield.…

Using the amazing Mutagen Python library I was able to completely strip out all the metadata! import mutagen mutagen.File(“example.opus”).delete() It…
