Newbie questions about OGG Vorbis...

I am interested in OGG Vorbis since I am trying to find the best way to shrink music file sizes. All my music are currently in MP3s and I'm starting to run out of disk space. Just a small decrease in file size would save me alot of space.

I have some questions about VORBIS:

What's the easiest and best encoder for converting MP3s to OGG?

I have heard that converting MP3s to OGG loses quality, so would converting an MP3 to WAV, then converting the WAV to OGG improve the quality?

How does OGG's Bitrate settings work? What is OGG's equivalent for a high quality VBR MP3?

Thanks!

If you really want to do so, it's possible even with Winamp. And I think I saw in some thread here that Oggmachine does that too.

No, these two are actually one and the same thing.

I'm not too familiar with Ogg, but my quess is that settings -q 5 and higher gives what you need.

So, does this mean that converting mp3 to ogg would be a bad idea? I want to keep the quality intact if possible.

Thanks!

In this case, it's a bad idea. Any kind of transcoding is a bad idea.

Yes, quality would suffer. Unless you wrap the mp3 in Ogg container

Ok. I guess I'll keep them in MP3 Format.

Thanks.

how do they come about?  I grabbed a few of your torture test files: tamsjam, rushing, duel, wait, queen (another 1...)  I encoded them with Oggdrop (with Roberto's latest DailyVorbis) at the quality setting that had resulted in kbps reports of 90 to 101 from WinAmp 2.79 when I encoded and then played Sade's "Paradise" yesterday.  All these examples had lower encoding rates.  Is the problem these samples pose that the encoder doesn't "recognize" their complexity so as to use higher rates?  I'm really puzzled :confused: by this matter -- today I also encoded "The Infernal Dance" from Stravinsky's Firebird, and even that piece, seemingly complex, was encoded at significantly lower rates than "Paradise."

to make this mroe clearly

you cant never restore the loss of quality you have done with encoding into mp3 or any other format..

if you coulde it would be lossles compression.


yuo can NEVET get better quality than you source under cmopression of anykind


so as using you mp3 an converting into ogg then the ogg compresis WILL not try to encode the data from you cd but tha data from you mp3 which allredy contains loss of quality.

now re-encoding it agian will result in further  loss of quality



to put it clear any step of compressin will losse quality..you cann't never GAIN quality by compression

that sounds like downgrade the file, not to compress it, true compression would be like rar

If you want lossless audio compression, use Monkey's Audio. It's much better (and faster!) than RAR.

my suggestion would be to burn a lot of your mp3 files onto cd-r; this way you can free up some of your hard drive space.  But keep the mp3 files as is, and just do your new encodes from now on in ogg vorbis.
