Wondering what the best way to make backups of Enhanced Audio CD’s is

I have been backing up all of my CD’s recently, using fr:ac to convert them to .flac files. I’ve encountered Enhanced Audio CD’s, where they now contain both data and audio tracks. For my dvd collection I have used dvd decrypter to convert all of them into .iso files, as I want to be able to emulate inserting the disk, but I’m not sure how to back up this type of CD. I would prefer for it to end up as something like an iso file, but I haven’t been able to find much about the best way to rip these.

Any help is greatly appreciated.
