where "--alt-preset standard" is placed you can use what ever LAME setting you want......of which there are many

a quick check shows Diana Krall's The Look of Love to be encoded with anything from 163 to 207 VBR - but then that will vary alot depending on the music

there is also a "--alt-preset extreme" setting, not sure of hte exact differance.

depending on how pickie one is one could pick different LAME settings for each type of music....I am sure classical music would be better encoded with different settings to death metal....but then this life thing tends to get in the way :-)
