Audio file formats????? MP3, AAC, MP3pro???

[imported_alex007]

(i didnt know into what categorie MP3 and audio files fell so if im in the wrong section, sry!!)

ok i recently bought an IPOD nano. my first mp3 player. SO im new with the handling of music files

with that said...........

I have a library of abou 150 music files, there all .mp3. I recently discovered that the musicmatch jubebox can convert .mp3 to .mp3pro. But what is the advantage here? Will the quality of sound still be the same or will the less file size also sacrifice music quality?

Also, Apple/itunes gives me an option to convert my .mp3 files to AAC, i did a couple of test, and the file size didnt change, and i didnt hear a change quality so whats the purpose for converting files?

Also some of my mp3's are 128 kbps, others are 192 kbps, are the 192 kbps better quality in sound, is the extar size in file worth it?

You shouldn't convert from one lossy format to another, it will just make it sound worse. If you want, you could rip your CDs to either MP3 or AAC for your new Ipod. AAC would probably sound better at a lower bitrate compared to MP3.

the problem is that dont usually but cd's, i just download the individual tracks

There's no way you're going to improve the quality of tracks you've already downloaded. You might possibly be able to reduce filesize with no other loss in some situations, but it's probably not worth the hassle, considering that you have so few songs.

192kbps is better than 128 in theory, but the only thing that matters is if you can hear the difference.
