Lame Advanced Stereo Setting "-m s"

[istraw]

There as been much discussion on "stereo settings" for LAME, but dMC isn't sending the correct parameters to LAME.

I can recreate a 192CBR STEREO file:

via the command line: lame.exe -r -m s -b 192 --CBR 10.wav s.mp3

Within dMC, CHANNEL = STEREO creates "Joint Stereo" files. Given there is a CHANNEL = "Joint Stereo" setting - why is dMC not sending "-m s"

-m <mode> (j)oint, (s)imple, (f)orce, (d)dual-mono, (m)ono
default is (j) or (s) depending on bitrate
joint = joins the best possible of MS and LR stereo
simple = force LR stereo on all frames
force = force MS stereo on all frames.

Can anyone provide a way in dMC to run "-r -m s -b 192 --CBR"?

I got it. I don't know why the "forced stereo" option is now available. I did update to 13.2, so let's assume that's it.

Sorry for wasting electrons.

I assume you are aware that forcing stereo can negatively affect your mp3 quality.

Here is one of probably many threads regarding stereo/joint-stereo.

I will summarize it for you, lame is smart enough to know when to apply joint-stereo or full stereo.

You should not have any real reason to to force stereo, doing so will lose quality for the same bit-rate at joint stereo, simply because the same information will be duplicated in both channels, lowering the available bits for real data.

The reason for the requirement of "hard stereo" is because I need to ensure this mp3 "sounds" similar to the source wav file. We don't want any deviation from the channels. Compression flaws are fine (ironically).

Yes, and contrary to your belief, joint-stereo will improve the sound making closer to the source.
