Confirmed that the current git head 75147-g9d742d2 fixed the regression.

> As for the L, R, M and S signal/noise ratio, did you test that without
PNS? That could have interfered. Could you tell me if IS sounded better
before or after without PNS?
I have tested {{{-b:a 128k -ar 44100}}}, {{{-b:a 192k -ar 32000}}},
{{{-b:a 320k -ar 48000}}}, {{{-q:a 1 -ar 44100}}}, {{{-q:a 2 -ar 48000}}},
without additional {{{-aac_pns enable}}} nor {{{-aac_is enable}}}
settings.
What optional settings should I test?
