An upright microphone.

We’re in the age of endless conference calls. So I decided to spruce up my audio hardware. Sadly, I don’t have the budget for a professional podcaster’s microphone. 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.…

Binary code displayed on a screen.

I’m trying to create some ridiculously tiny audio files. The sort where every single byte matters. I’ve encoded a small sample. But the opusenc tool automatically adds metadata – even if you don’t specify any. Using the amazing Mutagen Python library I was able to completely strip out all the metadata! import mutagen mutagen.File(“example.opus”).delete() It…

Mostly notes to myself, as a follow-up to this older post. This is a 3-step process.

Split the MKV by chapter This…

DVD-Audio (henceforce DVDA) is an unloved and mostly forgotten audio format. Nevertheless, there’s a large back-catalogue of music which is still trapped on ancient discs encoded in the proprietary MLP format.
