Yes, that's right. Moreover, you're converting between two lossy formats. The Ogg conversion is guaranteed to be of slightly lesser quality than the MP3 original (although I doubt you'd notice it). The space savings can be amazing, though. It is not uncommon for people to have several gigabytes of MP3s nowadays; converting it all to Ogg will enable one to store twice as much audio in the same space. > BTW, I've been testing wav-ogg compression.

I'm astounded at this performance. Ogg Vorbis is great, particularly when encoding from a non-lossy source (e.g. an uncompressed WAV file or a CD). As has been mentioned above, the benefits of converting from MP3 are less, but I beleive it is still worth it. Since most audio on the Internet right now is in MP3 format, the best thing to do is to try to get files encoded at a sample rate higher than the standard 128Kb/s (I aim for 160Kb/s or preferably 192Kb/s myself). Then you have a 'buffer' of quality that can be lost without compromising the audio too much when converting to Ogg (a lossy process). > Sox is the absolute bomb, btw.
