Hi,
Doesn't that boil down to not using joint stereo when the two channels have antiphase signals?
What is the reason for not chosing to use joint stereo in this case?

patrick.

If we have a situation where reduce bits should be taken from the M
channel instead of the S channel, then LAME is supposed to detect that
and encode the frame in regular stereo, not M/S.
If you want to pursue this idea, you might want to try forcing
all frames to be M/S using the "-m f" option.!
