If you're using lame.exe (sounds like this), you should use a frontent like lamedropXPD if you want other then the default settings. Get it here: http://rarewares.org/mp3.html To change settings (after starting it) use rightclick -> encoding options. You might want to have a look at the related sticky thread here to find lame settings with best quality/size ratio.
Hehe - you didn't say that you want to rip CDs to mp3. For this task there are several good & free programs, e.g. Exact Audio Copy (EAC), CDex, Audiograbber
If all of your CDs are in good condition (no scratches, no fingerprints, no aging CD-Rs) and your drive's internal error correction is good, using lame is definitely more important then using EAC.
In all other cases it'd be hard to decide. (Especially - how do you know your drive does a good job on audio extraction if you've never tried ripping a scratched CD with/without EAC with it? ;) ) Anyway - I'm glad that I don't have to decide, since EAC can encode to mp3 directly using lame :)
I hope I understood your brief question correctly ...
thank you very much!!
I want to know whether there is a software that support convert CD to mp3pro files??
As long as I knew, mp3pro is better than mp3.
Is that right??
Mp3pro is better then plain mp3 for low quality (and bitrate) like 96kbps and lower. The disadvantage is that on hardware players that are only mp3 compatible (and not mp3pro - I don't know any mp3pro compatible hardware player), it will sound worse than mp3s at the same bitrate because the SBR part which is responsible for improved quality is simply not decoded at all.
So using mp3pro only makes sense for usage in PC environment with very limited space - and in such a case there are as good or better alternatives like (HE)AAC or Ogg Vorbis. A good free AAC encoder is the one integrated in itunes, the one that comes with Nero Burning Rom is almost as good, but supports HE-AAC (which is AAC + SBR, comparable to mp3pro = mp3 + sbr) and is probably the best encoder for ~ 32 - 96 kbps bitrates at the moment. Ogg Vorbis is open-source + free (www.xiph.org). Many related audio tools you can get at www.rarewares.org ...
To answer your question directly (finally): There's a free mp3pro encoder by tompson IIRC, but you'll have to search yourself. (Using the search function at www.hydrogenaudio.org you'll have good chances to find a related thread.)
