📦 version 1.0, in ubuntu jammy

💖 JDELAY(1) 💖

okay bestie, welcome to the Jdelay Manual Page — yes that's the whole vibe, we're measuring sound card latency and we're gonna slay it ✨

🌸 NAME 🌸

jdelay — measure sound card latency. that's it. that's the girl. she does one thing and she does it beautifully 💅

🎀 SYNOPSIS 🎀

jdelay

no flags, no args, no drama. just run her. queen behavior honestly 👑

✨ DESCRIPTION ✨

okay so Jdelay is a simple JACK application you can use to measure the latency of your sound card. the way it works?? it does phase measurements on a set of tones to measure the delay from the output to the input. and the accuracy?? about 1/1000 of a sample 😭 that's actually so precise, not me being obsessed with a latency measurement tool fr fr

to actually use Jdelay, here's the lil ritual 🕯️:

  1. first, start a JACK server — she can't do her thing without it, iykyk
  2. then start jdelay in a console 🖥️
  3. it will create an input port and an output port — two lil babies 🫶
  4. connect them in some manner (for instance with the QjackCtl patchbay, iconic tool tbh)
  5. check the output on the console to see the delay, measured in samples 📏✨

and that's the whole flow bestie, no cap. connect the ports, read the number, vibe check passed 🌈
