WINDOWFILTER(1)

💖 WINDOWFILTER(1) 💖

okay bestie, so this one lives in the General Commands Manual section of the Unix manual, and it's genuinely one of those little tools that ate and left no crumbs. let's get into it 🫶

✨ NAME ✨

windowfilter — design an FIR digital filter by the window method

like, that's the whole vibe. window method. FIR. slay.

🌸 DESCRIPTION 🌸

so windowfilter is the program that designs an FIR digital filter for use with the resample program. it's giving sidekick energy but honestly? essential.

here's the thing though — it doesn't take a billion flags on the command line, no no. you literally just run the program and then type ? at its prompts, and it will explain all of its options to you right there. interactive king 👑

not me needing to tell you this: it has options, but you find them out by asking it nicely with a ?. no cap.
