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 speed

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).  YMMV.
