ESDFILT(1)

💖 ESDFILT(1) — the Enlightened Sound Daemon filter 💖

okay so bestie, we're in section 1 of the manual (that's the user commands girlies ✨), and this one lives in the Enlightened Sound Daemon family. Say hi to esdfilt.

🌸 NAME 🌸

esdfilt — the Enlightened Sound Daemon, but make it a filter 🎀

---

🦋 DESCRIPTION 🦋

So esdfilt is an EsounD filter. It's the sample esd filter program — like, the little demo one that shows you how filtering works — and what it does is implement halving and doubling. Optionally it can write the new data out to a separate file instead. That's the whole vibe. 💅

---

✨ USAGE ✨

Here's how you summon it:

esdfilt [OPTIONS] [FILE]

And here are the options, one by one, no skips, no cap:

• -s, --server=HOSTNAME — set which EsounD server you're talking to. You give it a HOSTNAME, bestie. 🫶
• -b — the output file should be 8-bit. Yes queen, downgrade that bit depth.
• -m — the output file should be mono. One channel and it's thriving.
• -r RATE — set the output rate to RATE. Whatever number you hand it, that's the rate now. 🌈
• -half — halve each sample. Cut it in two, periodt. ✂️
• -double — double each sample. Make it bigger, make it louder, main character energy. 🔥

🍓 what happens to FILE tho

If FILE is specified, the filtered output gets written there. That's it, that's the destination.

Otherwise — and this is the fun part — it gets written back to esound, so it changes the output going to the sound device. Not me casually rerouting audio through the daemon 😭✨

ngl bestie, if you don't name a file, your filtering is going straight at the actual sound output. That's the design, that's what it says, go off. 💀
