rip.sh — CD Ripper to Opus

Rips an audio CD to high-quality Opus files with a single command. Album metadata is fetched automatically from MusicBrainz — no typing required for well-known releases. Output filenames are sanitised to be safe on Windows, macOS, and Linux.

Two output modes:

Mode	Best for	Result
Single file	Audiobooks, audio dramas, live recordings	One .opus file, fully tagged
Individual tracks	Music albums	One .opus per track, tagged via MusicBrainz

Encoding uses all available CPU cores in parallel (via abcde + cdparanoia), so ripping a typical 70-minute album takes around 8–10 minutes including error correction.

Requirements

Manjaro / Arch Linux. Install all dependencies at once:

sudo pacman -S abcde opus-tools cdparanoia cd-discid wget eject python python-mutagen

For individual-track mode only, two additional AUR packages are needed (MusicBrainz track tagging inside abcde):

pamac install perl-musicbrainz-discid perl-webservice-musicbrainz
# or: yay -S perl-musicbrainz-discid perl-webservice-musicbrainz

The script checks all dependencies on startup and prints exact install commands for anything missing.

Usage

./rip.sh [OUTPUT_DIRECTORY]

Insert a CD, run the script, answer three short questions, done.
OUTPUT_DIRECTORY is optional — defaults to the current directory.

---

Example: audiobook / audio drama (single file)

Insert the CD, then:

$ ./rip.sh ~/audiobooks

When MusicBrainz doesn't know the CD

For obscure or self-produced CDs, the lookup simply falls back to a manual prompt:

⚠ WARNING: No MusicBrainz entry found (no network, unknown CD, or timeout).

  CD title: My Band - Live in Hamburg 2019
→ Title adjusted for filename: My_Band_-_Live_in_Hamburg_2019

Everything else works exactly the same.
