I am starting to run out of drive space. My music folder is 19gigs (legal, cds, bought from iTunes, ect...) I've heard that .ogg files are pretty good quality. Also smaller than other file types. Is this true? Or is there something better I should try?

.ogg does a pretty good job. With the stuff that you bought off of iTunes, you're pretty much not going to be able to do anything about those songs file size.

What format are the audio CD's you ripped in?

Most are mp3 while a hand full are m4a. I ask because ut2k4 soundtrack uses ogg and have small file sizes. Would it be a good idea to convert from mp3 to ogg? Or would I need to convert all my music to stereo if I wanted a file size difference?

You should convert to Ogg Vorbis because it's open source.

Or not. But it is a better standard than MP3, and was designed to decompress easily (in theory, portable devices enjoy longer battery life due to this). But you won't see a massive size difference, track-by-track.

FLAC is the all-time greatest, though. Except it only compresses to about 60% of the original size; my 350-some albums take up about 114GB in FLAC.

Why do you say that ? There are other lossless formats, some even compress better than FLAC, such as Monkey's Audio (.APE)...

Monkey's Audio is slower to en- and decode and doesn't compress much more than FLAC in the end. But the real reason I prefer FLAC to Everything Else is because FLAC isn't proprietary. The other (major) lossless formats are.

Well Monkey's Audio is not much slower than FLAC... as for being proprietary format, well then why is it written on the main page of their website :

Freely available source code, simple SDK and non-restrictive licensing - other developers can easily use Monkey's Audio in their own programs -- and there are no evil restrictive licensing agreements

? :hmm:

Anyway, I believe most users don't care about lossless audio, MP3 or OGG is enough for a lot of them, and the file sizes are much lower... then it's mainly a question of (variable) bitrate and sampling frequency.

You can only license proprietary technology. Just becuase they gave out an SDK and instructions on how how manipulate the file doesn't stick it in the OSS domain.

And FWIW, some of us can hear the difference. To us, it matters.

Have you heard of WavPack? It is lossless and keeps filesizes sane. A CD I was given had WavPack tracks which I converted to MP3 (to save space - I don't care about lossy compression when it comes to music, but the person who gave me the CD does) had an average size of about 15MB where MP3 would use about 5MB. Pretty damn good, considering it manages to pack the same information as a WAV file into 15MB. Not sure if it is open-source, but it's available for foobar2000.

That sounds quite stupid. GPL is a License too ...
