💖 LV2APPLY 💖

okay bestie, welcome to the lv2apply(1) page from the General Commands Manual — yes that's the manual name, she's fancy like that ✨

✨ NAME ✨

lv2apply — apply an LV2 plugin to an audio file 🎧🦋

🌸 SYNOPSIS 🌸

lv2apply [-Vh] [-c symbol value] [-i in_file] [-o out_file]
         [--control symbol value] [--help] [--version] plugin_uri

👑 DESCRIPTION 👑

so basically lv2apply runs an LV2 plugin on an audio file, and then writes the processed output to another file. that's the whole vibe. in → glow up → out 💅✨

The options are as follows, and yes we're going through every single one, no skipping:

  • -V, --version — print version information and exit. short and sweet, she just tells you who she is and dips 🎀
  • -c, --control symbol value — set control port symbol to value. this is how you turn the knobs from the command line, no GUI required, main character energy fr fr 🔥
  • -h, --help — print usage information and exit. your girl's got a whole tutorial for you 🫶
  • -i in_file — input file path. this is the audio you're feeding in, the before picture 🍓
  • -o out_file — output file path. this is where the processed audio lands, the after picture 💖

and of course there's plugin_uri — the plugin you wanna run, identified by its URI. iykyk ✨

🌈 ENVIRONMENT 🌈

  • LV2_PATH — a list of directories to search for LV2 plugin bundles, in the style of PATH. literally it's the same colon-separated situation as PATH but for LV2 bundles, so your plugins can be found wherever they're chilling 🧚

⭐ EXIT STATUS ⭐

lv2apply exits with a status of 0, or non-zero if an error occurred. so 0 = we ate, non-zero = something went sideways 😭

ngl if you're scripting this, check that exit status. it's giving "trust but verify" 💀
