[MP3 ENCODER] mid/side stereo at 160kbs?

[Anonymous]

I recently got an email from Tero Auvinen pointing out that the
FhG encoder does not use joint stereo at bitrates above 160kbs.

Should we mimic this in LAME?  Make the default "-m s" for bitrates
160 and higher?  (jstereo could still be turned on by specifing
"-m j".)

And what about VBR frames?  Turn off jstereo for 160kbs & higher frames?

I'm tempted by this because LAME's mid/side stereo switching criterion
has some flaws as compared to FhG's.  I have been trying a new
algorithm from that Johnston & Ferreira paper, but it still needs
a lot of work.
