Backup your CDDA media to a single-file flac with embedded cuesheet

On Arch Linux, the required packages are readily available:

abcde -1 -o flac -a default,cue

This will produce a couple of files:

A single flac file with an embedded cuesheet (this cuesheet does not include metadata nor track names).
A cuesheet file.

If you use mpd to listen to your audio, the cuesheet file needs a just a small edit to be usable:

sed -i /^FILE/s/FLAC$/WAVE/ cuesheet.cue
