Is it a good idea for me to covert my 190 mp3s to 160 aac? Will the quality suffer? Thanks.

If you need to reduce the size of your files because you're trying to fit more of them in the same disk space, then go ahead. Your quality will probably be about the same, although it would be better re-rip them.

Other than reducing file size, there is no real reason to transcode them.

Quality WILL suffer.

What you're doing is reconstructing full 44kHz/16-bit audio from a stream that's lost vital information through the data reduction inherent in lossy compression, and then re-compressing THAT through a *different* scheme, losing *different* information.

Result: The negative aspects and quality depreciation of BOTH compression methods, combined into one, neat, slightly (but not significantly) smaller package.

Hooray!

Thanks. I guess I'll have to recompress the 1345 songs that I have. (And the metadata!)

If you have the hard drive space, I would rip to Apple Lossless. Then you can later re-encode to any lossy format you want without the generational loss that Spheric Harlot described, for, say, putting on an iPod.

You don't have to touch the metadata, assuming you're ripping with iTunes. It replaces tracks that you re-rip, as long as the tags of the songs on the CD match the tags of the MP3s in your Library. Even your playlists stay intact.
