samples where aps or ape has a problem Options

[2Bdecided]

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.

With the many tests samples I've been trying, I am slowing coming to an even more contraversial conclusion... r3mix is often better than --aps!!!


Sorry - only joking! I should have tried this one on April 1.



Seriously though - I have found something which no-one here has ever said, probably because no one uses 128kbps CBR mp3: --alt-preset cbr 128 is often worse than -b 128 -h (i.e. the lame default). ap cbr 128 is probably better in the majority of cases (though I wouldn't bet my life on it), but there are many many samples where -b 128 -h is actually better than --alt-preset cbr 128.

This isn't a late April fool - try the samples listed in this thread for starters. Much of the time neither command line is transparent, so to some extent it depends on which artefacts you find most annoying; but there are some cases where lame default beats the "tuned" line hands down.


Just thought it was worth mentioning. I've already PMed ff123, who helped develop the command line behind --alt-preset cbr 128. Maybe the fact that it's worth trying other things (even other encoders) at 128kbps should be in the HA FAQ - and/or a subject for further lame tuning?


Anyway, what really interests me is the unanswered aps/e -Z issue - can adding -Z ever decrease quality? Please tell!

David.
