Not sure what you mean by RAW?
If you want to rip from an Audio CD to MP3, one of several freeware audio rippers will do it - If you want to encode an existing WAV file as MP3, there's a good many choices for that also.

http://www.google.co.uk/grphp?hl=en To be going on with, I'll cut/paste a recent rant of mine - freeware rippers versus Audiograbber
There's PLENTY of good freeware, 2 of which have SECURE extraction -
Audiograbber's one excellence is the noise reduction plugin.
(and THAT comes from elsewhere too)
www.exactaudiocopy.de EAC - The BENCHMARK in secure ripping, which also allows you to
quickly sample any uncorrevted errors, and maybe de-glitch them as
well!
Supports CD WRITING on many writers - YMMV!
(Postcardware, + donations welcome)
www.cdex.n3.net CDEX - Secure ripping by CD-Paranoia in the 1.40x betas
Nicer look than EAC, also reasonable interface for converting WAV-MP3
and Riff/WAV MP3 coded
(open-source)
http://www.zlurp.com/ ZLURP Ripper - take a look at the sreenshots - THIS is a strong
challenger indeed, though it lacks the secure ripping technology of
the other two.
(Donations requested, but not required)
There is also DBPowerAMP - but the interface is an acquired taste!

function

WHY ever pay for CD ripping software - and I DON'T mean WAREZ.
Want the best RIP at any cost (easy... EAC)
Drive doesn't like EAC? (try CDEX - Paranoia mode)
Want it FAST - if your drive is good enough then take off the
resync/correction modes.
