And important questions is: Are you re-compressing your mp3s to try to make them smaller or ripping your CDs again? (Or compressing your .flac files again?)

Well, you can either use a lower quality in LAME or switch to AAC. Using the Nero AAC encoder with Foobar is far easier than trying to mess with QT Pro.

AAC has better quality for the same bitrates when compared to MP3. As a results it goes transparent at lower bitrates than MP3.

Well, that's not my experience! I did some ABX'ing not so long ago with a few of my favorite tracks with much mid-high freq content which I assume is hard for an encoder. ~128kbit Nero encoding had nasty metallic/smearing artefacts, while I didn't hear a thing in my LAME -V 5 encode.

I'm using LAME 3.98 -V 5 happily and store A LOT of music on my 32G iPhone (using foobar2000 btw). Still haven't noticed an encoding artifact, but yet I don't listen much for those anyway when I'm working smile.gif

Can't wait for a HD-AAC encoder :P
