CDex is a free open source CD ripper. This has been my go-to CD ripper for years now.
- It has a no-nonsense interface.
- It supports ripping into several formats, including FLAC.
- It has support for CDDB for easy tagging.
- It has pretty good jitter correction, and was able to salvage songs that my CD player couldn't read.
- When selecting the meta tag for genre, you're forced to pick from their pre-defined list. So, unless you have basic taste, you'll have to change the tag after the fact.
