Are you talking about Dolby Surround signals, or are you talking about a normal
stereo signal that just has a lot of separation between L R? As far as I'm aware,
3d-surround information isn't destroyed, but it
| Someone told me, that using -mj will destroy 3d-suround information.
3D surround sound processing alter only "S" surround channel (L-R,
difference signals from both channels), "M" Middle channel (summing signal
L+R ie., mono) is not modified.
Processing is based only at equalizing in +/-
Someone told me, that using -mj will destroy 3d-suround information.
It is caused due switching from m/s to stereo and back.
Using -mf will solves this problem, because it will not switch between
the modes. In the past, i thought only fraunhofers joint-stereo has
a similar problem (phase lost

I was wondering why the mode is set to stereo by default with bitrates higher
than 160 kbit and not to joint stereo. Does it not make sense anymore with such
high bitrates or is there some other reason for this?

Did you noticed than using VBR, joint stereo files are bigger than regular
stereo ones?

Interesting observarion. I just tested this on a 1100 frame sample
and got:
lame -v -V 0: 724k
lame -v -V 0 -m f:679K

FhG uses sometimes intensity stereo, but of course for low bitrates because
it saves a lot of bits, but destroy the stereo image in the upper
frequencies.
Here is what modes FhG uses as default settings:
8,16k: mono
24 to 80k: MS/IS stereo
96 to 128 (160?): MS
from 160 (192?)

The feature list on the website is pretty impressive. Rafael (mpecker
author) seems to be very good at decoding the ISO documents. Maybe he's a
compsci/audio person or something,

Thank you. This explained it well. So are those techniques not implemented
