transqsh

a music transcoder to 96k opus and a few other codecs. it just does the thing.

todo

• fix the memory leak
• metadata
• [-] cover art copy
• really fix the memory leak
• get to 0 fails on our library (at 35 fails @ 2024-10-12)
• makes "./out.opus"??
• sync deletions

usage

well hi there!

• theres a nix flake, you can install that.
• if you can't install that you could cargo build --release and copy the output to a /usr/local/bin.
• you could also just clone the repo and cargo run --release -- --help
  • you need ffmpeg 6, ideally with fdk_aac if you plan to use that.

poke me if you need help, see my website for how

syncthing that shit

you can get the transcoded files onto your phone with a systemd timer and syncthing folder.

it's pretty simple. see my nixos module for reference.

my stack:

• desktop: transqsh, syncthing, systemd.{service,timer}
• iPhone: mobius sync, doppler
