This page describes how to securely rip audio cds to the lossy compression format Opus on GNU/Linux operating systems.
- may be the most mature secure cd ripping application for GNU/Linux systems. See rubyripper#Installation for installation instructions.
- Get it via package manager from your distributor's standard repositories if you're using something like Ubuntu 12.10 or later already. Otherwise install from source. (You'll have to install opus first.)
- Not strictly necessary but you may want to be able to rip to images with cue sheet and detect pregaps and pre-emphasis. cdrdao should be available from your distribution's default package repositories.
- Look up the read offset of your CD-ROM drive in AccurateRip offset database. (Command line tool
lshwmay help you find out what cd drive you have.)
- Click "Preferences" and insert the drive offset.
- Go to the "Codecs" tab and tick the "Other" box (and maybe untick other boxes like the preselected "Vorbis" box). Enter the path to the Opus encoder followed by
--bitrate 128 -o "%o.opus" %iin the field behind the "Other" box.
- Enter a cd into the drive
- Optionally enter metadata or edit automatically fetched metadata
- Click the button "Rip cd now!".
After the ripping process is finished you'll find the files in a subfolder inside your home directory.
