I, and I know a few of you, have long been looking for an equivalent tool under Linux to Windows’ Exact Audio Copy. I just stumbled upon a new (to me) possible contender: Whipper. Source at: GitHub - whipper-team/whipper: Python CD-DA ripper preferring accuracy over speedhttps://github.com/whipper-team/whipper Binaries appear to mostly be in your distro’s repos? Or so the github page reports, at least. It does use the new-ish libcdparanoia to do the ripping, under the hood – it seems that product has matured and more or less reached parity with EAC.
I have not tried this yet, so I can’t vouch for its quality relative to EAC, but it’s apparently popular enough that MusicBrainz’ Picard has specific support for its logfiles.
For proprietary-Darwin fans, the equivalent there now appears to be X Lossless Decoder: Lossless audio decoder for Mac OS X (undo.jp)https://tmkk.undo.jp/xld/index_e.html. YMMV.
