🌸 NAME 🌸

jackrec — a JACK toolkit client for recording audio 🎀

---

✨ SYNOPSIS ✨

jackrec -f filename -d seconds [ -b bitdepth ] port1 [ port2 ... ]

---

🦋 DESCRIPTION 🦋

okay so bestie, picture this: jackrec is a basic but honestly so useful audio recorder. It grabs audio from 1 or more JACK ports and writes it to a file on disk. periodt. 💅

The file format is always RIFF/WAV, no cap — and the samples get stored as signed integers. You can pick the sample bit depth with the -b option if you're feeling fancy. 🌈

Here's the cute part: your file ends up with as many channels as there are ports you listed on the command line — each channel carries the data recorded from exactly one port. One port, one channel, iconic behavior, no notes. 👑

You should generally specify the duration in seconds using the -d option. And if you don't? jackrec will just keep recording until something terminates it with a signal (eg. from Ctrl-c). literally the energizer bunny of audio recording 🐰

ngl, this app is not meant to be a heavy duty audio recorder. It started life as an example client showing how to handle threading and disk I/O in a JACK client — like, a demo, a lil teaching moment 🧚. But the way that it's actually a useful, simple recorder?? Obsessed. That's literally why it got included in the JACK toolkit. main character energy fr fr 💖

okay that's the whole vibe, bestie — mwah 💋
