Very bad choice.
But, no offence, that's just my personal opinion. I've "trained" my ears so that I am able to notice the difference between
it and
--alt-preset standard.
FYI, in the next version of Lame, --alt-preset and several of the other switches will be merged into --presets.
I won't go into the "r3mix switch and website" are outdated stuff again. Just a link to a list of alternative settings, so that everyone can pick which best suits them. Read
here.
