WMKBD(1)

okay so you literally opened WMKBD(1) — that's the page id, it lives in the General Commands Manual part of the shelf — and it's all about a tiny little tuner app called gtkguitune. no cap, this is the whole vibe. let's go 🎀

🌸 NAME 🌸

• gtkguitune — KGuitune 🎸✨

✨ SYNOPSIS ✨

gtkguitune

🦋 DESCRIPTION 🦋

bestie, this manual page is the quick lil rundown of the gtkguitune program. and real talk — it exists at all because the Debian GNU/Linux distribution needed one: the original program just... didn't ship a manual page. so someone stepped up. main character energy fr 💅

Guitune is a linux program for tuning guitars and other instruments, and the way it does it is Schmitt-triggering — which is just a fancy way of saying it counts the number of triggerings between two trigger levels over a certain amount of time. iconic, honestly 🧚

so here's the tea on why that matters. with FFT you need many samples to archieve the accuracy needed for tuning instruments. you often get times of around 1 second between two measurements, and the computer is quite busy in this second calculating the FFT. 😭 but with Schmitt-triggering you get a measurement every 10th of a second or even less (depending on the sample frequency you use). most of the time the computer is just... sitting there waiting for the samples. not me being a whole tuner for free 💀

the Trigger levels are adjustable, periodt. for a pure sine-wave the trigger levels could be zero. but for a wave wth overtones like the one in the figure above, you need a non-zero triggerlevel. it comes preadjusted to a level of 60% of the current maximum, which should be able to deal with most instruments. lowkey obsessed with that default 🫶
