I am sold on -V 1 --vbr-new; I have a TON of music (300G) ripped from private CD collection. If I now rip those rips to -V 1 --vbr-new, how much will I lose? I will save more than 10% space. I would like to do this without having to get the CDs back out!

How would I do this (what app? ALL2LAME will not write v2tags)? And if I do it, with the re-encoding make a significant difference if I am going down anyway?

Thanks you.

Very bad idea, Lame doesnt transcode its own files well, and transcoding is hazardous in general. Youll probably end up with less than 128 cbr quality files if you transcode V0 to V1. No ones found a way to make pleasing high quality transcodes yet, it might be practical for making medium quality copies for portables or streaming.

Thats such a tiny difference in space. Its not worth compromising your entire collection over. Not when you're talking about saving a few dollars worth of hard disk space.
