FM_DEMOD(1)

💖 FM_DEMOD — okay bestie, let's talk ✨

so like. fm_demod is the moment. it's a diagnostic tool for the codec2 library and its whole entire job is making an audio file out of signal samples. that's it. that's the girl. 🎀

---

🌸 SYNOPSIS 🌸

fm_demod usage: InputFMRawFile OutputSpeechRawFile

two arguments, no flags, no drama, we love a low-maintenance icon 💅

---

🦋 DESCRIPTION 🦋

okay so here's the vibe: you hand her an input raw file — and listen, the specs matter, no cap:

• 44.4 kHz
• 16 bit shorts
• and the FM signal is centered at 11.1 kHz

give her all that and she hands you back a file of demodulated audio samples. that's the whole trade. input FM samples in, speech-ish audio out. slay. 🔥

---

✨ OPTIONS ✨

ngl there aren't any actual flags here, it's just two positional arguments and they're both doing main character work:

• InputFMRawFile — the first argument, bestie. it's the file name of a file with FM signal samples. 🍓 and if you pass - instead of a name? the input gets taken from stdin. iconic.
• OutputSpeechRawFile — the second argument. this is the file name of a file that's gonna get created and filled with audio data. 🌈 and yep, if you pass - here too, the output gets sent to stdout. pipe it, redirect it, do whatever, she's flexible. 👑

fr fr: that's the entire option list. no hidden flags, no surprises, just two args and a dream. 🫶
