recbox

suckless audio recording of your modular via an USB interface (e.g. a scarlett) with a raspberry pi, 2 systemd units and a couple lines Rust

  • runs on a raspi laying around anyways
  • starts recording audio after boot, just plug it into the same power strip
  • use syncthing or scp to move recorded audio files
  • or just point the out dir to any external data drive (USB stick, NAS share, etc.)
  • dependencies: jack, cargo, syncthing (optional)
