I tend to agree with this, and I think we should disable
scalefac_scale for now (it can still be enabled with -q1
for testing) I'm also going to make the "old vbr"
mode the default, and put out a new release today.
scalefac_scale is similar to the new vbr code: it allows the encoder
to get the noise shaping even closer to the output of the psycho
acoustics, so it can make flaws in the psycho acoustics more
noticable.
Naoki's latest work makes a significant improvement to the psycho
acoustics, so you might want to try it with --nspsytune.
(scalefac_scale can still be enabled with -q1). Some of the stuff in
--nspsytune will make it into the default settings soon.
