Sorry if this was just posted: I'm looking for this issue but I'm still haven't found anything about it.
Here's the question: how to encode using LAME? or is there something to write MP3 files? I mean something to simply rip a cd ... I don't want to use programs like EAC or similar.
The second question is: what do you think is the best encoder?

Thanks for any help.

Do you want to encode to mp3 with foobar? If yes, then it's very simple:
1.Get CLI encoder from this site:
http://foobar2000.blogsite.org/

2.Download lame encoder and put it somewhere (in foobar's directory for example)
http://www.rarewares.org/files/mp3/lame-3.90.3.zip

3.Go to preferences ->components -> diskwriter and under output presets choose commandline encoder: --alt preset standard.
Click edit and under encoder field choose path where you copied lame.exe

4.Add wave files you want to encode to mp3 to the playlist, select all, right click, choose convert -> run conversion.
That's all!

If EAC is too dificult to you then try CdEx:
http://cdexos.sourceforge.net/
Using EAC or CdEx is recommended if you want to get high quality rips.
You can use foobar to that, but it is not recommended, because foobar do not provide secure ripping.

About your second question:
What's the best encoder? MP3 encoder? you should give more detailed information.
If MP3, then Lame is recommended. It's free and very well tuned.
If in general, then try to use search function. There were made a lot listening tests so you can get answer very easy.

Thanks a lot for your help WILU.
About EAC is not a difficult matter: the thing is that I prefer to find a solution where is possible do almost anything with one only program. Even if your point about quality and secure ripping is very important.
Btw, there's another quite nice and simple free ripping app., xtractor.

Thx WILU!
