Rubyripper and OggOpus: Difference between revisions

This page describes how to securely rip audio cds to the lossy compression format Opus on GNU/Linux operating systems.

rubyripper: may be the most mature secure cd ripping application for GNU/Linux systems. See rubyripper#Installation for installation instructions.
opus-tools: 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.)
cdrdao: 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 lshw may 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" %i in 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.
