How to properly downmix 7.1 track (DTS or FLAC) to stereo?
Hi guys,

I'm a bit at a loss here. I've always downmixed 5.1 tracks using Channel Mixer in Foobar2000, but it seems it doesn't fit here.

I need some tool or a plugin, which can turn 7.1 track into stereo properly. I searched the internet but I haven't found any suitable variants apart from VST plugin from Waves (DTS Neural pack at exorbitant price).

Can anyone help, please?

Use "Downmix channels to Stereo" included with every version of foobar2000.

Trim levels for this component (which can't be changed) are -3 dB for Center and -3 dB for Surround (side & back).  -3dB for LFE.  Works pretty good.

Thanks a lot! I never thought that simple plugin was this advanced.

From my test it seems that "Downmix channels to stereo" in foobar2000 1.3.15 uses 0 dB for LFE. I created 7.1 file with all channels with level 0% (-∞ dB) except LFE  with level 100% (0 dB), then downmixed it to stereo using "Downmix channels to stereo" in foobar2000 1.3.15. Resulted stereo file has peaks 0 dB in both channels.
