I was wondering if any other alt-presets (besides aps and ape) could benefit from the -Z switch. I know I read that api already uses noise shaping type 1 so you shouldn't use the -Z switch for that. How about using it for some of the abr/cbr presets?

Can --alt-preset cbr 192 be improved quality-wise with the -Z switch added?
