Anyone who knows about ripping/encoding from CD's knows that iTunes is meh, it's got nothing on LAME. There's a
Plug-in for iTunes so you can use LAME. The best setting is -V 0 --vbr-new. I think it keeps the bitrate on an avg of 260 kbps. Remember ya'll..the lower the bitrate, the crappier it sounds. Highest you can have on mp3 is 320, so 260 is'nt too bad.
Here:
This is your bible.
Edit: And heres a quote from my favorite website in the world. Talks about a transcode..
What is transcoding?
Put simply, a transcode is any audio file that wasn't encoded from an original lossless source, such as a retail CD (not created from lossy files) or a properly made lossless rip.
Why is transcoding bad?
Whenever you encode a file to a lossy format (such as mp3, m4a(AAC), ogg, or mpc) information is permanently lost. It doesn't matter what you do, it's impossible to get this information back without making a new rip from the original lossless source
(The original CD). If you re-encode it to a different format or bitrate, all you're doing is reducing the quality. This applies to any lossy to lossy conversion, so even if you convert down from 320kbps to 192kbps (Mp3 to Mp3) the final file will still sound worse than if you had just ripped from the original CD to 192kbps in the first place.
In other words, rip from CD's for best quality.
And to the OP, you wont get 20mb files unless it's a FLAC file(LAME nor iTunes can do this, only EAC). The higher the bitrate, the better it sounds, but unfortunately the bigger the file size. You can't have the best of both worlds.
Cliff notes:
Put in CD > iTunes >Open LAME plug-in > Choose -V 0 --vbr-new = Enjoy good quality mp3 ~260 kbps, and ~ 9 MB.
Put in CD > iTunes encoder > Choose 128kbps (Just like what you buy from iTMS) = Yuck, what a waste of time/space.
Next time listen to the same file thats 128kbps (or even a 192 kbps) vs 260 kbps. You'll thank me later.
When you use LAME, it rips a lot slower. This is the norm.
