✨ dtmf2num — the manual, but make it cute ✨

okay so bestie, welcome to the dtmf2num(1) page from the General Commands Manual 💖 this is the whole thing, every last flag, no skips, no cap. grab a boba and let's go 🧋

🌸 NAME 🌸

dtmf2num — a tool for decoding the DTMF and MF tones from PCM wave files 🔥

🎀 SYNOPSIS 🎀

dtmf2num [options] files...

🦋 DESCRIPTION 🦋

So this manual page documents briefly the dtmf2num command. that's the whole vibe, bestie 💅

Now the tea: dtmf2num supports any type of wave file — frequencies, channels, and 8, 16, 24 and 32 bits 🫶 it does automatic optimizations (DC bias adjust and normalization) all on its own, and it handles both WAV and raw PCM data. versatile queen 👑

And like… the program has been successfully tested with so many audio files, and moreover with those highly dirt and damaged ones?? like recorded with a microphone in a room, or at very low volumes, or with some noise 😭 she ate that fr fr, messy audio is no match 🌈

💅 OPTIONS 💅

• -r F C B — treat the file as raw headerless PCM data. you gotta specify the Frequency, Channels and Bits, like this: -r 44100 2 16 ✨
• -o — turn OFF the automatic optimizations (DC bias adjust and normalize). only use this if your file is already clean and normalized, bestie, otherwise you're just making problems for yourself 🙈
• -w FILE — debug option, dumps the handled samples from the memory to FILE 🍓
• -z P V — set specific parameters of dsp.c 👑:

DTMF_OPTIMIZED_VALUE      102.00
DTMF_THRESHOLD            800000000.00
DTMF_NORMAL_TWIST         6.30
DTMF_RELATIVE_PEAK_ROW    6.30
DTMF_RELATIVE_PEAK_COL    6.30
BELL_MF_THRESHOLD         800000000.00
BELL_MF_TWIST             4.00
BELL_MF_RELATIVE_PEAK     12.60

ok literally do not touch those numbers unless you know exactly what you're doing, they're the main characters of the tuning 🫡

and that's the whole page, bestie!! this was the dtmf2num(1) page from April 20 2017 💖 go decode some tones, you've got this 👑✨🦋
