I hear --alt-preset cbr 192 is the best quality lame can get in a 192kbit mp3 file, but it's joint stereo and I prefer stereo. What's the best command for a CBR 192kbit stereo file?

Ouch

the best command line for LAME, stereo 192kbps will be --alt-preset CBR 192, on the other hand the best command line for mono in 192kbps CBR will be something like --alt-preset CBR 192 -mm (if i recall correctly)

yet another person who hasn't updated her/his knowledge about join stereo for years

Forget stereo it will mostly just ruin you quality

Why would you want to use full stereo? LAME is the first Mp3 encoder to use a type of joint-stereo that will never damage the stereo image. I've tried using the --alt-presets with full stereo, and the quality is much worse then if J-stereo was used (Higher bitrate too). Try encoding using --alt-preset CBR 192 and hear the difference for yourself.
