I'm sure this has been asked before, but I can't find it, and it's not in the FAQ (it should be - please!)

On which samples is --alt-preset extreme audibly better than --alt-preset standard.
On which samples is --alt-preset insane audibly better than --alt-preset extreme.
On which samples is --alt-preset insane not transparent?

Cheers,
David.

I was searching for info on how -Z worked and found this old thread.

It seems to indicate that there are samples where using -Z to force use of that particular scalefactor can produce problems too, so the specific problem samples you tried, where -Z was no worse, might not be representative of the whole spectrum of music.

Of course, in the present thread, Dibrom has noted that certain samples (like those you tested) weren't known about then, so perhaps his opinion is now revised.

--alt-preset standard is well tested and lacks transparency only on rare cases. I don't think --alt-preset standard -Z has been tested anywhere near as much and shown to be OK, so I won't be using it, but I might try it if I notice a specific problem with APS (which won't be too often, now I mostly encode in Musepack mppenc --quality 5 --xlevel).
