Hello,

--r3mix is now for 3.91 a more or less out-dated presetting. One of the most tweaked setting is now based around the --alt-preset [standard/fast/insane]. The --alt-preset standard delivers 'archiving' quality VBR's around av. 160kbits.

I don't know anymore where to find the exact information, but you can try with google using : r3mix lame --alt-preset

Good luck
