👑 JCONV(1) — bestie edition 👑

okay so this is a page from the General Commands Manual section, and it's about jconv, and honestly? she's iconic. let's get into it 💖

✨ NAME ✨

jconv — it's a Convolution Engine for JACK, using FFT-based partitioned convolution with multiple partition sizes. that's the whole vibe. 🦋

🌸 SYNOPSIS 🌸

jconv [options][config-file][connect-file]

💅 DESCRIPTION 💅

so this manual page documents jconv briefly. that's the assignment. 💖

jconv is a Convolution Engine for JACK, based on FFT convolution, using the convolution engine for reverberation processing. the way it works is it distributes the calculation over up to five threads — one for each partition size — and those threads run at priorities just below the one of JACK's processing thread. no cap, that's the architecture. ✨

to run this program you need a config file and a wav file for convolution. demo config files? you can find them in the /usr/share/jack-jconv/config-files directory. 🎀

(you have to edit the path to your convolution wav file. yes literally you. go do it. 🙈)

a set of wav files you can download from Fons Adriaensen's web pages at http://www.kokkinizita.net/linuxaudio/downloads/index.html (jconv-reverbs.tar.bz2) — or you can use another convolution files which are supported by libsndfile. slay, options. 💜

some other info can be found in README and README.COFNFIG files in /usr/share/doc/jack-jconv. (yes, README.COFNFIG, that's not a typo on my part, that's literally what it says, i love her for it 💀)

🌈 OPTIONS 🌈

a summary of options is included below. here we go bestie, pay attention 📋

  • -h — display short help ✨
  • -v — print partition list to stdout. default: [off]
  • -L <nframes> — try to compensate <nframes> latency
  • -M — use the FFTW_MEASURE option. default: [off]
  • -N <name> — name to use as JACK client. default: [jconv]
