But only support:
-c, --channels, {AUTO[0],MONO[1],STEREO[2],SURROUND[6],SURROUNDEX[8]}

I need FL,FR,FC,LFE,SL,SR,TFL,TFR

DEE seems to be quite limited. Not all parameters of the encoders are fully adjustable. MainConcept TotalCode, Adobe Audition (old), Sound Forge, support many more channel layouts. The alogorithms are also different from what is available in other software. If you give a mono input, and select a high bitrate, the resulting stream will have a lot of unused space, while with other software the encoder will increase accuracy to use up all the bits.

You could upmix the file to 5.1 with silent channels, but that would likely be played back inconsistently on different devices. Stereo with blank channels works with AC-4, which requires a 5.1 input, and gives a stereo downmix. A patch through SoX can do an upmix/resample on the fly. AC-4 IMS also seems to be a "modern" pseudo-VBR codec, which doesn't overcode silence, and leaves unused bits.

Can I use this to encode a e-AC-3.5.1ch.192kb/s track to get some gain in the audio (may be 640kb/s)? or use eac3to for better encode? Is there any benefit to uplifting the audi bitrate as when we played this track on the system the aduio felt it bit low except for the voice (not much bass effect).

A change in bitrate won't improve the sound by itself. You can re-encode if you edited the track, for example, boosted the bass with an equalizer. 5.1 @ 192 kbit/s will always have poor quality with muffled high end and transients. That's just not enough data.

Can I do this (equalizer) edit in app like audition or can you please suggest an application for Windows 64bit.

This track has coversations in high volume and background score in low (not sure if its my soundbar outputting like that - like a voice boosting). But audio bitrate is a low for a movie soundtrack.

Here is the DeeGUI.au3 than can be interpreted by Autoit3.exe or use the DeeGUI.exe from here
You, my friend, are a National Treasure!!!

I'm not sure if you can help me with what I'm trying to do.

In the past, I have used DTS Master Audio Suite to replace an LFE channel in an MKV file that has DTS-HD MA audio. Now I want to do the same with an MKV file that has Dolby Atmos. Would you happen to know how I would go about this using your GUI and the steps I would need to take and/or command lines to retain Dolby Atmos in the original surround files?

Sorry but Dolby Encoder Engine can't create Dolby Atmos encodes, and replace a channel (LFE or other) implies decode first and recode to Atmos after.

Also with Dolby Encoder Engine can't create 3D sound only standard 5.1 or 7.1 2D like I say before.
I only know Audition 2017 to create 3D files from a source FL,FR,FC,LFE,SL,SR,TFL,TFR.

If you have an AVR 5.1.2 player you can decode the Dolby Atmos with Cavernize, replace the LFE and after recode it to eac3 3D with Audition.

Is there any reason for using DD+ instead of DD when encoding at higher bitrates (>448 Kbps)? Sound quality is the same to me, but maybe better ears (or equipment) can hear better quality audio from a DD+ stream.

High frequencies need more bitrate than 448 Kb/s for 5.1 channels, but without good equipment or old ears (like mine) maybe is the same.

For audio movies I like use AAC VBR with better quality/bitrate than DD CBR.

Why not opus? Compatibility issues?

AAC offers greater playback compatibility. Especially with televisions...

Yes, for better compatibility.
