Does the new exporter downmix 5.1 to stereo correctly?

Hi everyone!
I guess this is a question for devs but I have observed that in the new exporter menu you can select directly a “Stereo” output when exporting a 5.1 source.

Previous to this 3.4 update I always made a “Custom mix” export following the tips from this post:

Now I wonder if the new exporter, after selecting “Stereo” output, does the mixdown correctly applying -3 db to the center and rear channels, and discarding LFE.

This would be an interesting feature.
Anybody knows?
:thinking:

Custom Mix is now “Custom Export” in the Export Audio menu. That’s probably the safest way to go. You’ll have to do the -3dB adjustments “manually”.

You can make a test file with different tracks at different times to confirm what’s happening.

I have an old (no longer available) Dolby test DVD that I ripped, and I MIGHT have done a test once where I recorded myself saying “Left”, “Center”, “Right”, etc.

P.S.
In case you don’t have this, the sequence in Audacity is:

1= Left
2= Right
3= Center
4= LFE
5= Left Surround
6= Right Surround

If you want an answer from devs you will be better off posting this question as a Discussion on Muse’s GitHub (as the devs don’t hang out here on the Forum):

You will need a GitHub account for that - but those are free.

Thank you all for the answers.
“Custom Export” is probably the safest way to do it.
However, I did some comparison coding and couldn’t make a difference…
